Full Stack Engineer London (Oxford Circus) Hybrid: 2 days per week Reports to: Head of Mobile About Monument: We're building something genuinely rare: a financial brand designed for the mass affluent, the professionals, entrepreneurs and ambitious savers that traditional banks have systematically underserved for decades. We exist to make managing wealth simpler, smarter and more human, treating every client's wealth with the same care as if it were our own. We have over £7 billion in client deposits, a fresh funding round and a place on the Future Fifty, the UK's top pre IPO companies. The momentum is real. The Opportunity This is a build role for an engineer who wants to own their work end to end. You will design, develop and ship digital products that directly shape how Monument's clients manage and grow their wealth, working across the full stack from polished front end interfaces to resilient back end services. For the right engineer, this is a rare opportunity: meaningful ownership on a product that matters, at a pre IPO challenger bank, working with modern tooling and an AI first engineering culture that prioritises outcomes over process. What You'll Do Build, deploy and scale high-quality, secure and maintainable mobile applications across front-end and back-end systems, with full ownership of your code from architecture through to production monitoring. Collaborate closely with Product, Design and Data colleagues to define problems, shape hypotheses and ship working solutions at pace. Apply an AI-first approach to engineering, using tools such as Claude, GitHub Copilot and AI agents to accelerate development, testing and ideation without compromising quality or security. Instrument everything you build, tracking performance, behaviour and conversion to inform data-driven decisions on what to build next. Contribute to product strategy by identifying opportunities for technical innovation and automation across Monument's digital experiences. Ensure operational excellence across your work, building for reliability, scalability and compliance in a regulated financial services environment. Help define and evolve engineering standards, architecture patterns and development best practices as the team scales. Champion simplicity in design and implementation, building systems and interfaces that are intuitive, elegant and frictionless for clients. The Challenges You'll Tackle Monument's clients are discerning and have high expectations. Building experiences that feel genuinely premium, not just functional, requires craft as much as capability. Speed and quality must coexist. Shipping fast in a regulated environment means knowing where to move quickly and where to apply rigour. The full stack is genuinely full. You will be expected to contribute meaningfully across front end, back end and infrastructure, not camp in one layer. AI tooling is evolving fast. The challenge is not to use it for the sake of it, but to build the judgement to know when and how it genuinely improves your output. The Mindset Bias to Action. Make decisions with the information available. Do not wait for perfect conditions. Ship, learn, iterate. Radical Ownership. Accountable for the quality, performance and reliability of what you build, not just the code you commit. Challenge with Intent. Push for better solutions through evidence and technical rigour, even when the easier path is available. Intellectual Humility. Let data and results guide architectural decisions. Adapt when evidence changes, even when it means revisiting previous calls. Low ego, high standards. Confident in technical convictions, collaborative in approach, focused on outcomes. What You Bring Proven full-stack engineering experience, delivering production-ready applications using React, Node.js and AWS on web and mobile platforms. Hands on experience with iOS or Android native development, or React Native for mobile first product work. Strong working knowledge of RESTful and GraphQL APIs, serverless architectures and CI/CD pipelines. Comfortable in TypeScript and JavaScript, with experience in cloud native ecosystems and modern tooling. A track record of using data and experimentation to guide technical and product decisions. Demonstrable experience with AI powered engineering tools, with a considered approach to where they add genuine value. Experience working in agile, product led teams where speed, collaboration and ownership are the norm. Familiarity with UK GDPR data handling obligations and an understanding of what it means to build in a regulated environment. Experience with event driven systems and database technologies such as PostgreSQL or DynamoDB is advantageous. Exposure to financial services, fintech or other regulated environments is a plus but not a requirement. What's In It For You Build products that real clients use at a pre IPO challenger bank with genuine commercial momentum. No legacy constraints, modern tooling, an AI first engineering culture and the autonomy to own your work end to end. Be measured by what you ship and its impact, not by ticket velocity or meeting attendance. Our Values At Monument, our values shape how we make decisions, how we treat each other when things get hard, and how we show up for clients who expect more than standard banking. We set ambitious goals and hold ourselves to them, not because it looks good, but because our clients' outcomes depend on it. When something isn't working, we say so early, learn from it, and move. We don't wait for perfect conditions, and we don't protect egos over progress. We work as a genuine team, which means real collaboration, honest conversations when we disagree, and shared accountability when things go wrong. We know better decisions come from different perspectives, so we actively value the range of experiences and backgrounds our people bring. We're always asking whether there's a smarter way to do what we do, not for the sake of change, but because standing still isn't an option in the market we're in. Benefits 28 days annual leave plus 8 bank holidays Performance related bonus structure Equity after probation Enhanced pension (9% employer contribution + 1% match when you contribute a minimum of 1%) Private health insurance with family cover Optical and dental cover Online GP service for you and your family Life assurance Flexible hybrid working, including options to work from abroad Enhanced parental leave Equal Opportunities Monument Bank is an equal opportunities employer. We are committed to creating an inclusive environment for all employees and applicants. We welcome applications from individuals of all backgrounds and do not discriminate on the basis of age, disability, gender reassignment, marriage or civil partnership, pregnancy or maternity, race, religion or belief, sex, or sexual orientation.

Openr is transforming how the hospitality industry manages and shares data. By centralising recipe, product, and pricing information, we help hospitality businesses seamlessly connect to platforms like Deliveroo and Just Eat, as well as EPOS and other customer touch points. We've recently closed a significant funding round and are backed by Azzurri Group, one of the UK's most successful hospitality investment platforms. With strong market traction, we're now looking for a Principal Engineer. About the Role We're looking for a senior backend focused engineer to join our engineering team. This is a hands on role where you'll be designing and building the systems that power our platform, while helping set the technical direction for how we grow. You'll be a go to person for architectural decisions and a mentor to engineers around you. We're after someone who's as comfortable pairing with a junior developer as they are making calls on system design. We invest heavily in each other's development here, and that applies at every level. What You'll Be Working With Our backend runs on AWS Lambda, TypeScript, Node.js, and PostgreSQL, with infrastructure managed in AWS. On the frontend we use TypeScript, React, and React Query. While this role is firmly backend focused, having a working understanding of the frontend helps when collaborating across the stack. You don't need to have used every one of these technologies before. What matters most is that you're an experienced engineer who picks things up quickly and enjoys getting stuck into new problems. What You'll Be Doing Technical Leadership You'll play a key role in shaping how we build things. That means owning architectural decisions, identifying the right trade offs between speed and sustainability, and ensuring our systems are reliable and performant. You'll contribute to our product roadmap from a technical perspective and help the team navigate complex dependencies and risks. Building This isn't a role where you stop writing code. You'll be hands on daily, delivering high quality backend solutions, improving our development workflows, and tackling the harder problems that come with a growing platform. Growing the Team You'll mentor engineers across the team, helping them develop their skills and confidence. You'll also be involved in recruitment, from screening candidates and reviewing code challenges to helping shape how we onboard new joiners. Communicating You'll regularly translate technical concepts for non technical stakeholders. Being able to explain the "why" behind decisions clearly and calmly is a big part of this role. What We're Looking For You're an experienced backend engineer who is confident designing and building systems in production. You have strong experience with TypeScript, Node.js, SQL, and relational databases. You've worked with cloud infrastructure, ideally AWS and serverless architectures. You've led the delivery of complex technical projects and know how to bring others along with you. You think carefully about system design, making pragmatic choices that balance quality with pace. You communicate well and enjoy working with people across different disciplines. Nice to have, but not essential (we're happy to support you in growing into these) Experience building or scaling SaaS products. Familiarity with event driven architectures. Background working with integration heavy platforms. An interest in security best practices. What We Offer Flexible hybrid working. Two days a week in our Central London office in Farringdon, the rest from wherever works for you. No out of hours support. We believe great work happens when people have balance. Real influence. You'll have direct input into architectural decisions and the technical direction of a growing SaaS platform. This isn't a role where decisions are made above you. A learning culture. Dedicated time and support for developing new skills, working with modern cloud native technologies. A collaborative team. We genuinely enjoy working together and supporting each other's growth. 25 days holiday per year plus Bank Holidays Life Assurance (4x salary) Income Protection (75% salary after 26 weeks) Access to WeCare Employee Assistance Programme Cycle to Work Scheme Annual eyecare voucher with Specsavers Wrkit Savings & Benefits platform We encourage applications from people of all backgrounds. If you're excited about this role but don't tick every box, we'd still love to hear from you. Curiosity and a desire to learn matter more to us than a perfect checklist.
