Senior Product Engineer - Frontend

Overview

Our client is a well-funded stealth startup within the Life Science area and is building the groundbreaking AI operating system for drug discovery software.

They’re hiring a Senior Product Engineer to own the interfaces where scientists interact with the platform. The stack is React and TypeScript on the front end, with Java and Python services behind it. You’ll live mostly in the frontend and API layers, with the range to go deeper when the product demands it.

Salary and Location

Salary: £120,000-£150,000 + equity
Location: London - Hybrid 2-3 days a week onsite

What you’ll own

• The product surfaces where scientists interact with the platform, end-to-end through to production
• Trust surfaces (provenance, citations, confidence) rendered so a scientist can check the work behind any answer
• The component systems and frontend architecture that let a small team ship polished product quickly
• Close work with founders, customers, and domain experts, turning ambiguity into shipped product

What they’re looking for

• 4+ years of engineering experience, with deep React/TypeScript expertise and solid full-stack range
• You’ve shipped product experiences people rely on, and you can point to them and a strong product taste .... you sweat interaction details, performance, and polish
• A background that held a high bar: FAANG, a top AI lab, or a startup/scale-up with a great product engineering function
• Nice to have: genuine curiosity about building with AI, or experience shipping AI-powered features

This is a high-ownership role at a company of roughly a dozen people and it is fast-moving, direct, and high-stakes, with responsibility that will outrun your title.
