Do you have experience building and shipping exceptional UX at an early-stage startup or customer-facing product?
Are you excited by real ownership, product influence, and shaping the frontend experience of a genuinely category-defining AI product?, 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.
