Our client is a well-funded stealth startup within the Life Science area and are 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 front end and API layers, with the range to go deeper when the product demands it.

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 with experience with Python/Java on the backend.
  • 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.

How to prepare for a job interview at Foundation Partners

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Foundation Partners uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Showcase Your Projects

Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
