Full Stack Engineer

JOB SUMMARY As a Full Stack Engineer, you'll be a key set of hands helping build out internal AI applications. You'll work closely with the Head of Engineering, taking well-defined requirements and turning them into highly available, reliable, secure, and performant APIs, microservices, and internal web portals. This is a pure delivery role. Our client needs a self-starter who can pick up tickets, write clean code, and integrate standard web technologies with modern LLM APIs to help the business run smarter and faster. JOB RESPONSIBILITIES - Hands-on development: focus primarily on writing production-grade code, building out specific features for internal platforms. - Full-stack execution: build robust backend services and integrate them with clean, functional front-end interfaces for internal teams. - API integration: work with the Head of Engineering to connect proprietary data with cutting-edge LLMs using established APIs and emerging agent development frameworks. - Testing and deployment: ensure delivered code is well-tested and plays nicely within existing cloud infrastructure. QUALIFICATIONS Technical Stack: - Backend: Python and/or Node.js. - Frontend: modern JavaScript/TypeScript frameworks. - Infrastructure: general experience with GCP (Cloud Run, Vertex AI) and basic Infrastructure as Code (Terraform). Experience and Skills: - Solid full stack experience: proven experience writing and deploying robust services using Python or Node.js, alongside modern frontend frameworks (e.g. React, Vue, or TypeScript). - Cloud familiarity: comfortable working within modern cloud platforms (preferably Google Cloud Platform) and understand containerized deployments (e.g. Docker, Cloud Run). - API & integration skills: strong experience building and consuming REST or GraphQL APIs. - Self-starter: comfortable picking up tasks and working independently to deliver them on time, asking for unblockers when necessary. - AI interest: you don't need to be an AI researcher, but you should be excited to work with LLMs and basic agentic systems. - UK time-zone overlap: able to commit to at least 4 hours of daily overlap with UK business hours (09:00–17:00 GMT/BST). - English proficiency: professional working proficiency in written and spoken English (CEFR C1/C2).
