We are exclusively recruiting for a health-tech AI startup in London that is building the AI infrastructure that makes LLMs safe, transparent, and reliable - so it can actually be used in clinical settings. They are backed by Google DeepMind, HuggingFace and one of the leading VC funds globally.

We're looking for a Founding Product Engineer to join the team of Oxford Scholars, doctors, and ML Interp Researchers to help build the company from the ground up; someone who thrives in ambiguity, cares deeply about users/customers, and is excited to shape both their product and engineering culture from day one.

The Role

• Design, build, and ship features across the stack—frontend, backend, and infrastructure.
• Work primarily with [e.g., TypeScript, React, Node.js, Postgres, Python, and AWS/GCP]; help evolve the stack as the product scales.
• Build intuitive user experiences with modern frontend frameworks and tools.
• Architect backend systems, APIs, and services with scalability, performance, and simplicity in mind.
• Set up and maintain CI/CD pipelines, monitoring, and automated testing.
• Collaborate closely with the founders, product, and design to prioritise and rapidly iterate on features.
• Talk to end user/clients directly, gather feedback, and translate it into product improvements.
• Make pragmatic tech decisions balancing speed, quality, and long-term maintainability.
• Lay the foundation for engineering best practices i.e. code quality, documentation, security, and testing.
• Help build and shape the early engineering team and culture.

What They Offer

• Meaningful equity. You’ll be treated like a true co-founder.
• A say in what they build, how they build it, and who they hire.
• Opportunity to shape a product from 0-1 with real-world impact.
• Flexibility, autonomy, and a culture of trust.
• Top of the range compensation & comprehensive health insurance.
