Founding Engineer (Frontend) - AI-native Workspace

Salary: Up to £170k + equity Location: London, onsite Experience: 5-10 years (startup or customer-facing product background are a bonus)

I'm excited to be continuing our partnership with a pre-seed AI startup building agentic AI systems that radically improve how knowledge workers think, decide, and get work done. This is not another chatbot. This is an AI-native product being built from first principles by engineers from elite technical environments (e.g. Palantir, Citadel).

As the company evolves into a more product-led, consumer-style experience, they're now looking to hire their first dedicated Frontend Engineer, someone who can own and shape the entire user experience from the ground up.
