Founding AI Engineer at EF-backed pharmaceutical AI startup

Join an elite, EF-backed startup as a Founding AI Engineer to automate competitive intelligence for the multi-billion dollar pharma industry. Based in London, you'll work alongside Cambridge founders to build LLM-driven systems that replace manual clinical trial monitoring for enterprise clients. With a £100k-£150k salary and founding equity, this is a rare opportunity for a high-agency engineer from a top-tier university to own the technical roadmap of a company moving from pre-seed to scale. Skip the incremental updates at Big Tech and build the future of life sciences intelligence from day one.
