Senior Developer, Python, Django.

Senior Python / Django Developer (Contract)

Remote (from the UK) | Initial 3‑month contract with strong extension potential

Build high‑impact data products in a real production environment

We're working with a London‑founded cloud software company building data‑driven tools for the fresh produce sector. Their platform combines ETL pipelines, analytics, optimisation models and planning capabilities to help organisations reduce waste, protect margins and make faster, better‑informed decisions.

They're now looking for a Senior Backend‑leaning Developer to join on a 3‑month contract to accelerate delivery of a new Sales & Operations Planning (S&OP) module, already live as a working React + TypeScript prototype.

This is a hands‑on build role, ideal for a senior developer with deep data‑pipeline expertise and enough full‑stack exposure to add real value in a small, highly technical team.

The Role

You'll be working on a production Django application used by real customers, connecting sophisticated data logic to a modern frontend.

What you'll be doing:

• Shipping a new S&OP module within an existing Django platform
• Connecting a React 18 + TypeScript 5 frontend to real customer data
• Orchestrating complex pandas DataFrames, including:
• Stock projection logic
• Gate filtering
• Attribute resolution
• Debugging and validating data pipelines against real business logic - not just happy‑path execution
• Collaborating closely with a strong technical team using clear specs and robust tooling

What We're Looking For

Essential experience

• Strong Python backend development
• Deep hands‑on experience with Django and pandas
• Proven delivery of data‑heavy, customer‑facing products
• Methodical, structured approach to data pipeline debugging
• High standards for correctness, validation and self‑QA

Nice to have

• Ability to read and review React & TypeScript
• Experience with SSE or WebSocket streaming
• PostgreSQL JSONField and multi‑tenancy patterns
• Familiarity with agentic AI development tools (e.g. Claude Code)
• Exposure to supply‑chain concepts (FEFO, stock projection, service‑level KPIs)

What's Provided

• Company laptop
• Dedicated staging environment with demo customer data
• A working React / Django prototype
• Integration guides and transform library references
• Weekly technical syncs
• Claude Code access for AI‑assisted development
