Description

We are seeking a highly skilled Full Stack Developer to join our team in a high-impact, client-facing capacity. You will be instrumental in architecting and deploying robust, scalable applications for a diverse range of clients across the UK and EMEA. This isn’t just a coding role; you are a consultative partner—capable of translating complex business requirements into secure, serverless architectures and presenting best-practice improvements directly to customer stakeholders.

Key Responsibilities

  • Cloud-Native Development: Architect and build high-performance web applications using React, Node.js, and TypeScript. Own the full lifecycle, from frontend UI components to backend business logic.

  • Serverless Architecture: Design and deploy event-driven solutions leveraging AWS Lambda and other AWS services. Be adept at managing serverless state, permissions (IAM), and performance tuning.
  • AI-Accelerated Workflow: Proactively utilise AI-assisted development tools (e.g., GitHub Copilot, Cursor, Claude) to accelerate delivery, automate testing, and refactor legacy code while maintaining strict manual oversight for security and quality.
  • Automation & CI/CD: Build and manage automated pipelines that bridge the gap between application code and infrastructure deployment, ensuring a seamless “push-to-deploy” experience.
  • Consultative Leadership: Act as a subject matter expert in client pods, mentoring junior engineers and confidently presenting architectural roadmaps to customer stakeholders.

  • Experience with REST APIs and third-party APIs.
  • Strong working knowledge of containerisation technologies (Docker) and orchestration platforms (Kubernetes, ECS).
  • Automated testing experience.
  • Excellent communication and interpersonal skills, with a proven ability to engage with technical and non-technical stakeholders.
  • A consultative mindset with strong problem-solving and analytical skills and ability to communicate technical concepts to non-technical stakeholders.
  • Comfortable working in agile, client-facing environments with autonomy and ownership.
  • Able to commute when required for client or team sessions (occasional).

Benefits

  • Remote-first working with flexibility around client needs.

  • Projects with global brands & public sector leaders, working on real-world impact.
