- Integrating Claude AI (Anthropic API) to deliver features such as document summarisation, semantic search, and conversational assistants
- Designing and building RESTful and GraphQL APIs to support real‑time, dynamic user experiences
- Creating responsive, accessible UI components using modern React patterns (hooks, context, server components)
- Implementing secure authentication and authorisation using JWT and OAuth, including role‑based access control
- Optimising application performance, improving page load times through code‑splitting, caching, and backend tuning
- Building scalable data pipelines and prompt orchestration layers to improve AI response quality and reduce token usage
- Collaborating closely with product, design, and data teams in an agile delivery environment
- Owning CI/CD pipelines and cloud infrastructure across AWS and Vercel
- Frontend: React, Next.js, TypeScript
- APIs: REST, GraphQL
- AI: Claude (Anthropic API)
- Auth: JWT, OAuth
What we’re looking for
- Strong experience building production‑grade full‑stack applications
- Solid knowledge of React/Next.js and Node.js ecosystems
- Experience working with APIs (REST and/or GraphQL)
- Familiarity with cloud platforms (AWS preferred) and modern deployment practices
- Exposure to AI/LLM integrations is highly desirable
- A pragmatic engineer who can move between frontend, backend, and infrastructure
