About the Company
Our client is a scaling, product-led technology business building modern cloud-native platforms at the core of its global growth strategy. Their platforms are central to revenue, scalability, and long-term product delivery. With disciplined engineering practices and a high-calibre team, this is an environment where quality, clean architecture, and technical ownership are genuinely valued.
The Role
This is a senior engineering position for someone who wants architectural influence, technical ownership, and the opportunity to shape how a platform operates. You'll join a platform engineering team responsible for systems that directly underpin global product delivery, working across the full stack with modern tooling and cloud-native infrastructure. The expectation at this level is clear: strong fundamentals, clean architecture, and confident decision-making. You will operate as a senior individual contributor with meaningful influence over design, quality, and technical standards, without heavy management layers getting in the way.
Key Responsibilities
- Design and evolve core platform systems with scalability and long-term maintainability in mind.
- Deliver full-stack features using TypeScript / Node.js on the backend and React on the frontend.
- Architect and deploy cloud-native solutions on AWS across application and infrastructure layers.
- Define and manage infrastructure through Terraform and Infrastructure as Code practices.
- Own CI/CD pipelines and release processes end to end.
- Apply test-driven development and strong automated testing principles throughout delivery.
- Contribute to architectural decisions and long-term platform direction.
- Troubleshoot complex production issues across the full stack.
- Collaborate closely with product and delivery stakeholders to shape technical solutions.

- Solid database fundamentals across relational and NoSQL (PostgreSQL, DynamoDB or similar).
- Proven experience operating within modern CI/CD environments.
- Clear understanding of scalable system design and cloud-native architecture.
- Right to work in the UK.
Nice to have
- Experience writing backends in Rust.
- Exposure to AI-powered developer tooling and agentic workflows.
Why Apply?
- Senior-level ownership without heavy management layers.
- Modern tech stack and disciplined engineering practices; clean architecture is a genuine standard here.
- Real architectural influence over a platform central to global growth.
- £60,000 to £70,000 base salary plus performance-based bonus.
