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 such as Palantir and 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. This is a true founding-level opportunity as the 3rd engineering hire.
You’ll work directly on:
- Building high-performance, real-time AI-native interfaces
- Crafting intuitive UX for complex autonomous workflows
- Developing beautiful, responsive frontend systems in TypeScript & React
- Creating product experiences users genuinely love using
- Influencing product direction, interaction design, and frontend architecture
They’re particularly interested in engineers who have:
- Worked on developer tools, web-based IDEs, or highly interactive products such as Gitpod, GitHub, or Cursor-style environments
- Built customer-facing or prosumer applications
- Strong product intuition and a sharp eye for UX/UI
- Experience operating in fast-moving startup environments
- A desire to own frontend strategy, not just implement tickets
Tech stack:
- TypeScript
- React
- AI-native workflows & tooling throughout engineering
Bonus points for:
- Some backend experience for optionality
- Experience with PLG or consumer-style products
- Design sensibility and ability to bridge engineering and product experience
What we’re looking for:
- Strong commercial & product mindset – you care deeply about user experience and outcomes
- Comfortable in ambiguity and zero-to-one environments
- Proven ability to ship quickly and iterate with users
- High ownership mentality and startup pace
- AI-native way of working (LLMs are tools, not toys)
Why join now?
- Real founding-level ownership and influence
- Small, elite team that ships fast
- Well‑funded with long runway
- Opportunity to define the frontend experience of a next‑generation AI product
- Not another boring B2B SaaS platform – this is something people will genuinely want to use
