Backend Developer - Django Fast API/PostgreSQL

We're building a next-generation SaaS platform for the UK education sector.

You'll work alongside our senior full-stack developer, building the APIs, data layer, and integrations that power the platform.

• *What you'll work on: Django/Fast API, PostgreSQL with row-level security for multi-tenancy, Celery for async task processing, Redis caching, AI API integrations (Anthropic Claude), Microsoft 365 OAuth/SSO, and vector search with pgvector. You'll also help shape CI/CD pipelines and deployment workflows.
• *We're looking for:
• Solid Django and Django Fast API experience
• PostgreSQL — not just basic queries, but indexing, query optimisation, and ideally row-level security or multi-tenant patterns
• Experience with Celery and Redis for background processing
• Familiarity with pgvector or Elasticsearch for search
• Git, code reviews, and CI/CD (we use Google Cloud Run)
• Understanding of API design, authentication flows (OAuth 2.0, JWT), and data privacy considerations
• SOLID and DRY principles to ensure code maintainability; reusable component libraries and shared logic hooks.
• Modular systems that handle complex data flows efficiently; scalable state management and data caching strategies.
• Bonus: Experience with AI/LLM API integration, UK GDPR or working with children's data
• *The role: Full-time, remote with 1–2 days per week in the office in Chatteris, Cambridgeshire. Agile team, 2-week sprints, and a codebase that's being built properly from the start.
• *Why join: You'll be one of the first engineers on a product with a genuine social mission, working with cutting-edge AI technology in an area of education, where getting the engineering right actually matters. Pilot school already lined up, clear roadmap, and real commercial traction ahead.
