Circuit Medical is transforming how pharmaceutical companies generate educational and marketing content. Our leading platform is already being used at numerous leading pharmaceutical companies. We're looking for leading AI Engineers who can take real-world customer and market requirements and turn them into working, scalable products; fast. You'll own the full journey from prototype to scalable, production-grade systems. The level of role e.g. Principal, Senior will be dependent on candidate experience.

What we need

Someone who is equally comfortable whiteboarding an agentic architecture, scaling prototypes, and shipping the code behind it. You live at the intersection of R&D and product delivery, and you're motivated by building products and features that scale and demonstrate returns, and not just those that demo well.

Your job

Translate customer and market requirements into AI-powered product features, swiftly moving from concept to working software

Design and build agentic architectures using LLMs: from single-agent workflows to multi-agent systems

Lead on R&D cycles: research new approaches, prototype rapidly, evaluate rigorously, and ship what works in a rapid timeframe

Build scalable, production-ready systems: not throwaway prototypes

Collaborate across product, engineering, and commercial teams to ensure what you build solves real problems

Ship improvements continuously, driven by data and user feedback

Someone who can demonstrate experience with LLMs, AI agents, and agentic design patterns e.g. tool use, RAG, planning, orchestration

Able to translate requirements into clear technical direction, and then execute on it

Genuinely curious: you read papers, run experiments, and stay close to the frontier

Entrepreneurial: you treat each challenge as an opportunity to shine and are tenacious

Motivated by building unique, scalable products that demonstrate impact in a real-world setting

Resilient and comfortable operating with ambiguity; you don't wait for perfect specs, but continuously ask questions and offer improvements

Independent and self-driven, and a strong collaborator

Driven by customer feedback and customer centricity

Able to demonstrate at least 5 years' experience in similar roles

Stack

Python, React, data engineering pipelines, implements evals to drive robust product performance understanding, API integrations, CI/CD, AWS cloud infrastructure experience

Bonus: experience deploying models in different languages, working to ISO27001 ISMS standards, experience with biotech/pharma

You need a fully defined roadmap before you start building

You prefer deep specialisation in one narrow area over breadth and ownership

You're looking for a slow, predictable environment

What we offer

Competitive salary and benefits

Opportunities for professional growth

Flexible work hours and remote work

Collaborative, inclusive work environment

Chance to work on cutting-edge AI technologies with real-world impact
