Python / Django Developer

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

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)
