Backend Developer (Python/FastAPI) – AI Agent & API Integrations

We’re looking for a backend developer to integrate AI agents with our API layer and ensure reliable, secure, and scalable data flow across the system.

What You’ll Do

- API Engineering: Design, build, and maintain RESTful services using FastAPI (or Django REST/Flask with willingness to transition).
- Agent Integration: Connect AI agents to backend services, orchestrate inputs/outputs, and standardize response handling.
- Database & Persistence: Design schemas and write efficient queries for PostgreSQL (or similar relational databases).
- Caching & Queues: Implement Redis for caching, rate-limiting, and message queuing where needed.
- Async & Background Jobs: Build background workers for long-running tasks and event-driven processing.
- Real-time Status: Implement WebSockets for live progress updates and status streams.
- File & Document Pipelines: Handle uploads, storage, retrieval, and metadata management for documents.
- Observability & Reliability: Build robust error handling, logging, monitoring hooks, and safe retry patterns.
- Documentation: Maintain clear API specs, integration notes, and internal guides.
- Testing: Write unit and integration tests to ensure stable releases and confident refactors.

What We’re Looking For

Must Have

- Robust Python fundamentals (async/await, type hints, clean architecture).
- Experience building APIs with FastAPI (or Django REST/Flask and ready to learn FastAPI quickly).
- Solid PostgreSQL / relational database experience.
- Hands-on Redis experience (caching and/or queues).




- Strong REST API design practices (versioning, validation, pagination, auth patterns).
- Comfortable with Git, code reviews, and maintainable code standards.
- Ability to read, debug, and improve existing codebases.

Nice to Have

- AWS experience (e.g., S3, ElastiCache, cloud networking basics).
- WebSocket implementation experience.
- Background processing frameworks (Celery/RQ/Arq/Temporal, etc.).
- Third-party API integrations and webhook design.
- UK property domain familiarity (a plus, not required).

What Matters Most (How We Evaluate)
- Impact > tenure: What you shipped, improved, or scaled matters more than years.
- Curiosity & craftsmanship: You’ve built something meaningful outside of tutorials.
- Debugging strength: You can trace issues across services and logs systematically.
- Learning agility: You ramp up quickly on unfamiliar systems.
- Integration mindset: You understand how APIs, databases, workers, and agents connect end-to-end.

Not a Fit If...
- You need step-by-step handholding for core backend work.
- Your experience is mostly tutorial-level with little production application.
- You struggle to work with existing codebases or explain your past work technically.
