Agentic AI Engineer (life sciences)

About Healx

Healx is an AI-powered tech bio company that is redesigning drug discovery. With 10,000 rare diseases affecting 400 million people globally, 90% of which have no approved treatment, Healx is on a mission to pioneer the next generation of drug discovery to help rare disease patients in need. We combine data, artificial intelligence and deep pharmacology expertise to develop treatments more quickly and cheaply than traditional drug discovery.

Diversity and inclusion sits at the heart of our mission to help people with rare diseases, and we believe that attracting and empowering a diverse team is critical to achieving this goal. We welcome applications from people from all backgrounds and walks of life.

Below we have included the qualities that we feel are required for you to excel in this role; however we appreciate that people can apply transferable skills and experience. If you think you have what it takes, love our mission and resonate with our values but are worried you don't tick every box – we still want to hear from you and encourage you to apply!

Our values

• Care for Rare – Rare disease patients are at the heart of what we do

• Grow as individuals – We are learners always seeking to enhance our expertise

• Win as a team – We strive to remain inclusive and diverse and we celebrate successes and lessons together

• Innovate and deliver – Our mission requires rapid innovation and calculated risks that won’t compromise our high standards

The role

• Build and refine AI-agentic workflows on our internal framework to help drug discovery scientists generate the best testable therapeutic hypotheses to progress.

• Translate discovery problems into agent designs, working out where an agentic approach genuinely adds value, and where it doesn’t
• Integrate agents with our knowledge graph, proprietary methods, scientific literature and other sources so they reason over the right evidence for each problem
• Expand and maintain our existing genAI tools so they keep pace with the team’s needs and a fast-moving ecosystem
• Contribute to how we evaluate agentic workflows, helping shape sensible evals, testing and quality standards as the practice matures
• Write clear, maintainable, well-documented code that others on the team can build on

• You've built and shipped LLM-agentic systems that deliver real value — agents that use tools, orchestrate multi-step workflows and behave reliably in production. We care more about what you've built than how long you've been at it.

• Strong software engineering fundamentals — you write clear, tested, maintainable code that others can build on
• Fluency with the modern LLM/agent toolkit — model APIs, prompting, tool use, RAG, and the patterns this fast-moving ecosystem is converging on (MCP, agent frameworks, evals).

• A pragmatic sense of where an agentic approach genuinely helps and where it doesn't, and you enjoy working closely with non-engineers — the kind of person who'll sit with a scientist to understand what they actually need.

It’s a bonus if you have:

• Experience in drug discovery, biology, or another life scientific domain — or simply a real appetite to learn one

• Familiarity with knowledge graphs or reasoning over structured or heterogeneous data
• Experience building evaluation harnesses or testing strategies for LLM systems
• A track record of picking up unfamiliar domains quickly and becoming useful fast
• Interest in or experience with biotech / techbio and its impact on patient outcomes
