Own the AI backbone of a regulated bioprocess SaaS platform — end to end. Chesham, Buckinghamshire (hybrid — 3 days in office) Biopharm Services builds analytics software used by the biopharma industry to predict manufacturing cost, performance and sustainability in regulated pharma environments. Our 18-year proprietary bioprocess dataset is the moat. We're now moving it into an AI-native SaaS platform — and we need a Senior Python / AI Engineer to own that transition from the inside. What you’ll own:

• EcoInsight and DataAgent — Python/FastAPI services, LLM orchestration pipelines and data infrastructure, accountable for reliability and security.
• Directing AI agents (Claude Code, Copilot, DevOps MCP) — reviewing and hardening what they produce, not just prompting.
• Observability across LLM features using Langfuse-style tooling so behaviour is explainable and audit‑ready.
• Cross‑stack integration with JS/TypeScript engineers — designing APIs that keep Python and browser services loosely coupled but coherent.
• Contributing to the canonical data model across products — architecture decisions that matter, not just tickets.

In 18 months, success looks like: EcoInsight and DataAgent are stable, observable and contractor‑independent. 80%+ of new Python work flows through the agentic SDLC with clean QMS‑traceable provenance. Small expert team. Real ownership. AI‑native from day one — not as a future aspiration.

• Confidence using AI coding tools and owning the output.
