We're working with an early-stage, AI-native SaaS company building intelligent agents for some of the world's largest enterprises, operating in a huge industry that AI has barely touched. Global organisations are already customers, the team is small and high-performing, and they move quickly.
This is a Founding TypeScript Engineer role for someone who wants very high ownership. You'll work directly with the VP Engineering on the core product, owning features end to end: understanding the problem, deciding how to solve it, shipping it and making sure it works. AI sits at the centre of the product.
Responsibilities
- Build and ship frontend and backend product features across a TypeScript stack
- Develop APIs, data models and integrations into complex enterprise systems
- Build agentic workflows, including prompting and tool use
- Turn ambiguous problems into simple, working solutions and fix issues without waiting to be asked
- Own your work from design through to production, using AI heavily in how you build
Key Requirements
- 5+ years' software engineering experience, ideally building SaaS products
- Strong TypeScript, which is non-negotiable
- A track record of shipping products end to end, across frontend and backend
- Hands‑on experience with agentic engineering
- High agency, sharp attention to detail and strong product judgement
- Startup or early-stage experience
- Experience integrating with enterprise systems
- Comfort working in ambiguity and shaping product direction
Details
- Office-first, 3/4 days per week in central London
- Founding seat
- High ownership and direct influence over product and technical decisions
- AI at the heart of the product and engineering environment
A strong opportunity for a Founding TypeScript Engineer who wants full end-to-end ownership, real influence over product and technical decisions, and the opportunity to build at an early-stage AI company.
