Senior AWS Cloud Engineer Abingdon £75,000pa plus bonus & benefits 1 day onsite per week: MARS has partnered a global consultancy to hire in a Senior AWS Cloud Engineer to join a talented IT function. This strategic delivery partners work, spans both private and public enterprises on a global basis, delivering real impactful change, improvements and transformation for their clients. With an amazing company culture and values, this business really puts its staff at the forefront of what they do. My client is building multi-cloud platform department, and their estate today is Microsoft Azure; but they're establishing a presence in Amazon Web Services (AWS) next, with Google Cloud Platform (GCP) to follow. Therefore, they are looking for an engineer whose deepest expertise is in AWS the AWS expert who will lead the design and build of the AWS landing zone and set the standards we carry into it. Because that AWS environment does not exist yet, your day-to-day work will initially be in Azure, and you will need to be fully willing to design, build and support in Azure while the AWS platform is established. This is not a people management role. rather, the Senior Cloud Engineer is the go-to expert: the person who solutionize complex requirements, leads on architecture decisions, represents the cloud function in project and client conversations, and sets the technical benchmark for the rest of the team. Our client is looking for an AWS Cloud Engineer with the following skills: SME-level experience designing, building and operating production workloads in Amazon Web Services (AWS), ideally including the foundation of a new AWS environment (landing zone, multi-account structure, identity, networking and guardrails). Willingness to learn and gain the ability to deliver in Microsoft Azure. Our AWS environment is not yet built, so a significant share of early work will be designing, building and supporting Azure workloads. Prior Azure experience is a strong advantage, but a clear commitment to working across both platforms is essential. Infrastructure-as-Code: strong, hands-on proficiency in Terraform and/or AWS CloudFormation or CDK for provisioning and managing AWS resources, with the ability to work in Bicep for our Azure estate. IaC must be the default approach, not an occasional tool. CI/CD pipeline expertise: proven experience building and maintaining pipelines in Azure DevOps and/or GitHub Actions, ensuring automated, repeatable infrastructure deployment. Scripting proficiency: Python, PowerShell and the AWS and Azure CLIs used regularly for automation, operational tasks, and reducing manual intervention. Integration services: proficient in AWS integration services (EventBridge, SQS, SNS, Step Functions, Lambda and API Gateway) and able to work with Azure Integration Services (Logic Apps, Service Bus, Event Grid and API Management) for integration design and implementation. AWS platform foundations: experience with multi-account design using AWS Organizations and Control Tower, IAM and IAM Identity Center, VPC networking, and security services such as GuardDuty, Security Hub and CloudTrail. API Development: solid experience with SOAP and REST APIs, including design, development, and secure management. Experience with GitHub version control, including branching strategies and code review practices. Any AWS certifications will enhance your application: AWS Certified SysOps Administrator - Associate (or AWS Certified Solutions Architect - Associate); AWS Certified Solutions Architect - Professional; AWS Certified Security - Specialty or demonstrable equivalent security engineering experience with a commitment to achieve this certification. Our client is offering a highly competitive salary and generous benefits package includes: Life Assurance, Income Protection, pension contributions and 27 days holiday (not including bank holidays). They also operate a profit share scheme so that our people share in the success of the business. The profit share bonus is based on company performance and typically paid out in March and September. Joining this impressive business also brings many social benefits. They have a full social calendar with Spring activity days, Christmas events, a 2-day Summer event and 4 sponsored weekends a year.

Lead Overhead Catenary System Engineer, High Speed Rail Our client is recruiting a Lead OCS Engineer to take technical ownership of the overhead catenary system on one of the most complex railway infrastructure programmes ever delivered in the UK. The standards that govern high-speed rail are not the same as those applied on the conventional network, and the person they are looking for will understand that distinction from direct experience. Your day-to-day purpose is to lead the technical assurance of the OCS design, provide professional leadership across the discipline, and make sure that what the contractor specifies and installs genuinely meets the programme's requirements. This is a client-side role. You will be the technical authority for OCS Engineering on the programme, setting the standards that the contractor works to, assuring the design against those standards, and working through issues where the two do not align. You will provide technical advice across the wider programme and to external stakeholders, coordinate with colleagues in other engineering disciplines to ensure that OCS does not sit in isolation, and contribute to governance processes including peer reviews and stage gate assurance. You will also develop best practice and look for opportunities to drive consistency and efficiency across delivery, drawing on engineering innovation where it adds genuine value. The role sits at the intersection of several complex engineering interfaces. Prior to contract award, the team acts as system specifier and carries responsibility for railway systems integration as civil design progresses. That responsibility does not go away after contract award: your team retains accountability for successful integration throughout. The programme environment is fast-moving and the demands on it change, so the ability to stay focused and effective in a shifting landscape matters as much as technical depth. The role can be based in London, or Birmingham What you need to bring Your background is in overhead catenary or overhead line engineering on programmes of genuine scale and complexity, and that background must include high-speed rail. Experience gained only on the conventional UK network is likely not sufficient for this role in isolation. Our client needs someone who understands how high-speed standards differ from Network Rail standards, and who has applied those differences in practice, most likely through experience on comparable programmes in other countries or across international systems. Interoperability is central to the work. You will need to understand OCS and OLE in the context of the wider railway system, not as a self-contained discipline. That means a working knowledge of interoperability standards and how they sit alongside national technical specifications and applicable legislation. You will have led engineering on large, multi-disciplinary infrastructure programmes, managing competing technical and commercial demands where cost and schedule are live pressures. Experience of the Common Safety Method for risk evaluation and assessment, and familiarity with UK construction regulations including CDM, are expected. You will be able to communicate clearly with contractors, colleagues and senior stakeholders, and you will have the confidence to hold a technical position under scrutiny. Useful to have Experience on programmes of comparable scale and ambition to HS2, particularly where you have worked across the full lifecycle from requirements and design through to construction assurance. A background that spans more than one railway system or national context, giving you the breadth to apply standards critically rather than by rote. Experience of value engineering and whole-life cost thinking on major infrastructure programmes. If this looks right for you, please send your CV across and we will be in touch.
