4C Strategies in Warminster is looking for a Senior Backend Engineer to lead integration and development of backend services on the Exonaut platform. This role involves designing and implementing robust backend solutions while working collaboratively within the engineering team to enhance overall system performance. The ideal candidate should have strong skills in Java and SQL, a deep understanding of integration patterns, and a genuine excitement for tackling complex engineering challenges in a hybrid work environment that supports flexible arrangements.
Who we are 4C Strategies builds organisational readiness and military training management software for clients in over 70 countries. Our flagship product, Exonaut , is used by NATO and allied forces to plan, run and evaluate exercises in real time. Our consultants and engineers work alongside armed forces across the UK, Europe, North America and beyond to deliver training and exercise management solutions. Your Role Much of this hasn't been designed yet - and that's the point. We're connecting Exonaut to a fast-growing landscape of systems (a data lakehouse, customer ERP platforms, optimisation engines, partner platforms) on one of the most significant training transformation programmes in UK defence, and a lot of the hard problems are still open. We want a senior backend engineer who's energised by that kind of ambiguity: someone who can take a vaguely defined need, work with the team to figure out the right shape, and build it. You'll own and evolve parts of the Exonaut platform itself, not just wire systems together - real product engineering at the seams of several moving parts. Scope will shift, requirements will surprise you, and - with the support of a strong team around you - you'll have the autonomy to make the calls that matter. This sits within a large, multi year MoD programme - one of the most significant training transformation efforts in UK defence today. This is a Senior role with real ownership. You'll lead substantial pieces of work end to end - designing, choosing the right patterns, and seeing them through to production - and help shape how the wider team works: the standards we hold ourselves to, the tools we reach for, and how we test and observe what we build. Day to day you'll collaborate with other engineers, project managers and designers on the programme, with senior stakeholders on the customer side, and with peers across the wider 4C engineering organisation - where the IC track is treated as a first class career path alongside management. What you'll do Figure out and build how Exonaut talks to everything around it - a data lakehouse, customer ERP systems, optimisation engines and partner platforms - often from a rough idea rather than a finished spec, reading and writing data reliably with maintainability, observability and security designed in from the start. Work across a modern data and backend stack - built around Java and SQL databases - alongside pipeline orchestration and transformation tooling, choosing the right tool for the problem rather than the other way round. Big parts of the stack are still ours to decide - you'll make real architecture calls, not inherit someone else's, so judgement and pragmatism matter more than experience with any one tool. Introduce event driven and change data capture (CDC) patterns where they help us keep data flowing in near real time across systems. Help raise our engineering standards around code quality, automated testing, CI/CD and observability - building the pipelines and test automation that let us ship changes safely and often, with quality and operability treated as first class engineering concerns, not an afterthought. Mentor and coach engineers across the team - not just juniors - and help grow our backend and integration engineering practice inside 4C. Extend and modify the existing Exonaut platform, building the backend services and APIs that connect it to surrounding systems - owning integration contracts, performance and security. Work directly with stakeholders on both sides - our own project managers, designers and engineers, and the customer's technical and non technical people - drawing out what's really needed, explaining technical trade offs in plain language, and making sure what we build genuinely serves the people who use it. About you A capable engineer with backend and data experience who has independently led substantial pieces of integration, backend or data work - connecting systems together and seeing it through to production - and who still likes being close to the code. Comfortable building backend services and APIs (REST and/or event based) and integrating with third party systems such as ERP platforms, data stores and external engines - with a good grasp of integration patterns, authentication and performance. Strong in Java (or a comparable backend language you can bring across) and solid SQL - we value the engineer over the exact language. Comfortable with version control, code review, automated testing and CI/CD pipelines - you treat test automation and safe, repeatable delivery as part of building, not a separate phase. Energised rather than unsettled by ambiguity: you can pick up a new stack quickly, you're happy to define the problem rather than only solve a specified one, and you make sound calls when requirements are still moving. We care more about that than any specific technology you already know. Sound judgement around system and data design - including integrating with a data warehouse / lakehouse - and good instincts for when to use streaming or event driven approaches versus batch. Pragmatic about quality: you instrument what you build and care as much about how it runs in production as how it looks in code review. A strong communicator who can hold a technical conversation with engineers and a plain language one with project managers, designers and senior customer stakeholders - internal and external, including in regulated environments. A mentor by instinct who lifts the people around you and helps spread good practice. Fluent written and spoken English, as required for security cleared defence work and for clear communication with UK customer stakeholders. This role requires the successful candidate to be a UK national and eligible to obtain UK Security Clearance (SC). Candidates who already hold current UK SC clearance will be at an advantage; however, we also welcome applications from individuals who meet the eligibility requirements and are willing to undergo the SC clearance process. A genuine interest in our mission - software that helps armed forces, public safety and resilience organisations train, prepare, and respond. Research shows some people only apply when they meet every requirement - if you don't tick every box but recognise yourself in much of the above, please apply anyway. We'd genuinely like to hear from you. What you can expect from 4C Strategies Warminster based, with hybrid working - typically around three days a week on site at our office or a customer site. Some of the work needs to be done on site, and the exact pattern can vary with the programme's needs, but we're supportive of flexibility where the work allows. Easily commutable from Bath, Salisbury, Trowbridge and the surrounding area. Competitive salary, reviewed annually Pension Scheme with 5% employer contribution Private healthcare including dental Enhanced family leave (maternity, paternity and adoption) 25 days holidays (plus bank holidays) Life Assurance Cycle to work scheme Work Extras Discounts at over 80 retailers Company social events Why Join 4C Strategies If you're happiest when the path isn't drawn yet, this is a rare chance to own hard, open problems on a large, multi year programme - real scale, real production systems, and the freedom to shape how they're built - with a collaborative team to figure the hard parts out alongside you. You'll work alongside experienced engineers and military specialists, with the individual contributor track valued as highly as management, so you can grow without leaving the code behind. The work matters: what you build helps armed forces, public safety and resilience organisations train, prepare, and respond. If you want senior level ownership on systems that are used in earnest - not a backlog ticket factory - this is that role. 4C Strategies is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.

We're connecting Exonaut to a fast-growing landscape of systems - a data lakehouse, customer ERP platforms, optimisation engines and partner platforms - on one of the most significant training transformation programmes in UK defence, and many of the hard problems are still open. We want a Staff Engineer to act as technical lead for the team: a full-stack engineer whose centre of gravity is backend and integration work, who is energised by that ambiguity and can take a vaguely-defined need, shape it with the team, and build it across the stack. You'll lead through influence rather than formal authority, partnering closely with our Engineering Managers and Product Managers. You'll own and evolve parts of the Exonaut platform itself, not just wire systems together - product engineering at the seams of several moving parts, from the services and APIs underneath to the interfaces people use. There's a clear programme direction and a strong team around you; within that, scope will shift and you'll have the autonomy to make the calls that matter. This is a Staff role with real ownership. You'll lead substantial pieces of work end-to-end - designing, choosing the right patterns, and seeing them through to production - and steward the technical direction across the team: the architecture, the standards, the tools, and how we test and observe what we build. You'll still spend meaningful time hands on in the code, with the balance gradually tilting toward leadership - your impact growing through the design sessions you lead, the engineers you mentor, and the architecture you shape across data, integrations and APIs. Day to day you'll collaborate with other engineers, project managers and designers on the programme, with senior stakeholders on the customer side, and with peers across the wider 4C engineering organisation - where the IC track is treated as a first class career path alongside management. What you'll do Hold the technical vision for our work on the programme, in close partnership with Engineering Management, Product and Delivery - and stay close enough to the code to lead by example. Figure out and build how Exonaut talks to everything around it - a data lakehouse, customer ERP systems, optimisation engines and partner platforms - often from a rough idea rather than a finished spec, reading and writing data reliably with maintainability, observability and security designed in from the start. Build full stack features on the Exonaut platform - the backend services and APIs, and the user facing interfaces on top of them - so the systems you connect are matched by interfaces people can actually use. Work across a modern stack - Java and SQL on the backend, Angular on the front end, plus pipeline and data tooling - making real architecture calls rather than inheriting someone else's, so judgement and pragmatism matter more than experience with any one tool. Introduce event driven and change data capture (CDC) patterns where they keep data flowing in near real time.

Mentor and coach engineers across the team - not just juniors - mentoring Senior Engineers toward Staff level scope, and help grow our full stack and integration engineering practice inside 4C. Represent engineering thoughtfully with customers, partners and 4C peers - presenting technical work externally and making sure the engineering perspective has a strong voice in cross functional and customer settings. Work directly with stakeholders on both sides - our own project managers, designers and engineers, and the customer's technical and non technical people - drawing out what's really needed, explaining technical trade offs in plain language, and making sure what we build genuinely serves the people who use it. About you An experienced full stack engineer who still enjoys writing code, with several years operating at Senior Engineer level or above and a track record of guiding non trivial technical work across a team or cluster of teams. Your centre of gravity is backend and data, and you're comfortable working up the stack into the user facing layer - so this suits a backend leaning full stack engineer rather than a front end specialist. Comfortable building backend services and APIs (REST and/or event based), integrating with third party systems such as ERP platforms, data stores and external engines, and building the front end on top - with a good grasp of integration patterns, authentication and performance. Strong Java and SQL, with working familiarity with Angular (or a comparable modern front end framework). We care more about depth and judgement than about an exact match - if you're strong in a neighbouring backend language and willing to work in Java, we'd still like to hear from you. You treat version control, code review, automated testing and CI/CD as part of building, not a separate phase. Comfortable being a team's technical point of reference - you lead through influence, partnership and consistently good judgement.

Our consultants and engineers work alongside armed forces across the UK, Europe, North America and beyond to deliver training and exercise management solutions. Your Role Much of this hasn't been designed yet - and that's the point. We're building new parts of Exonaut and connecting it to a fast-growing landscape of systems (a data lakehouse, customer ERP platforms, optimisation engines, partner platforms) on one of the most significant training transformation programmes in UK defence, and a lot of the hard problems are still open. We want a senior full stack engineer who's energised by that kind of ambiguity: someone who can take a vaguely defined need, work with the team to figure out the right shape, and build it end to end - from the user interface down to the data layer. What you'll do Build Exonaut end to end - the user facing screens, the backend services behind them, and the data that flows through both - often from a rough idea rather than a finished spec, with maintainability, observability and security designed in from the start. Figure out and build how Exonaut talks to everything around it - a data lakehouse, customer ERP systems, optimisation engines and partner platforms - reading and writing data reliably across systems. Work across a modern full stack - a component based web front end, backend services built on Java, and SQL databases - alongside pipeline orchestration and transformation tooling, choosing the right tool for the problem rather than the other way round. Big parts of the stack are still ours to decide - you'll make real architecture calls, not inherit someone else's, so judgement and pragmatism matter more than experience with any one tool. Introduce event driven and change data capture (CDC) patterns where they help us keep data flowing in near real time across systems.

Mentor and coach engineers across the team - not just juniors - and help grow our full stack engineering practice inside 4C. Extend and modify the existing Exonaut platform, building the front end features, backend services and APIs that connect it to surrounding systems - owning the user experience, integration contracts, performance and security. Work directly with stakeholders on both sides - our own project managers, designers and engineers, and the customer's technical and non technical people - drawing out what's really needed, explaining technical trade offs in plain language, and making sure what we build genuinely serves the people who use it. About you A capable engineer with full stack experience who has independently led substantial pieces of work - building both front end and backend, connecting systems together and seeing it through to production - and who still likes being close to the code. Comfortable building modern web front ends (a component based TypeScript framework, specifically Angular) as well as backend services and APIs (REST and/or event based), and integrating with third party systems such as ERP platforms, data stores and external engines - with a good grasp of integration patterns, authentication and performance. Solid SQL and strong Java (our backend language). Comfortable with version control, code review, automated testing and CI/CD pipelines - you treat test automation and safe, repeatable delivery as part of building, not a separate phase. Energised rather than unsettled by ambiguity: you can pick up a new stack quickly, you're happy to define the problem rather than only solve a specified one, and you make sound calls when requirements are still moving. We care more about that than about any specific technology you already know. Sound judgement around system and data design - including integrating with a data warehouse / lakehouse - and good instincts for when to use streaming or event driven approaches versus batch. Good product and user experience instincts - you care how the interface feels for the people using it, not just how the code reads. Pragmatic about quality: you instrument what you build and care as much about how it runs in production as how it looks in code review. A strong communicator who can hold a technical conversation with engineers and a plain language one with project managers, designers and senior customer stakeholders - internal and external, including in regulated environments. A mentor by instinct who lifts the people around you and helps spread good practice. Fluent written and spoken English, as required for security cleared defence work and for clear communication with UK customer stakeholders. Requirements This role requires the successful candidate to be a UK national and eligible to obtain UK Security Clearance (SC). Candidates who already hold current UK SC clearance will be at an advantage; however, we also welcome applications from individuals who meet the eligibility requirements and are willing to undergo the SC clearance process. A genuine interest in our mission - software that helps armed forces, public safety and resilience organisations train, prepare, and respond. Benefits Warminster based, with hybrid working - typically around three days a week on site at our office or a customer site. Some of the work needs to be done on site, and the exact pattern can vary with the programme's needs, but we're supportive of flexibility where the work allows.

Who we are 4C Strategies builds organisational readiness and military training management software for clients in over 70 countries. Our flagship product, Exonaut , is used by NATO and allied forces to plan, run and evaluate exercises in real time. Our consultants and engineers work alongside armed forces across the UK, Europe, North America and beyond to deliver training and exercise management solutions. Your Role Much of this hasn't been designed yet - and that's the point. We're building new parts of Exonaut and connecting it to a fast-growing landscape of systems (a data lakehouse, customer ERP platforms, optimisation engines, partner platforms) on one of the most significant training transformation programmes in UK defence, and a lot of the hard problems are still open. We want a senior full stack engineer who's energised by that kind of ambiguity: someone who can take a vaguely defined need, work with the team to figure out the right shape, and build it end to end - from the user interface down to the data layer. What you'll do Build Exonaut end to end - the user facing screens, the backend services behind them, and the data that flows through both - often from a rough idea rather than a finished spec, with maintainability, observability and security designed in from the start. Figure out and build how Exonaut talks to everything around it - a data lakehouse, customer ERP systems, optimisation engines and partner platforms - reading and writing data reliably across systems. Work across a modern full stack - a component based web front end, backend services built on Java, and SQL databases - alongside pipeline orchestration and transformation tooling, choosing the right tool for the problem rather than the other way round. Big parts of the stack are still ours to decide - you'll make real architecture calls, not inherit someone else's, so judgement and pragmatism matter more than experience with any one tool. Introduce event driven and change data capture (CDC) patterns where they help us keep data flowing in near real time across systems. Help raise our engineering standards around code quality, automated testing, CI/CD and observability - building the pipelines and test automation that let us ship changes safely and often, with quality and operability treated as first class engineering concerns, not an afterthought. Mentor and coach engineers across the team - not just juniors - and help grow our full stack engineering practice inside 4C. Extend and modify the existing Exonaut platform, building the front end features, backend services and APIs that connect it to surrounding systems - owning the user experience, integration contracts, performance and security.
