Member of Technical Staff / Product Engineer | AI Start-up

JBG/MTECHSTAFF AI & Machine Learning United Kingdom - Greater London £100K - £160K / Year

I'm working with a highly ambitious, well-funded AI startup that's building intelligent software to transform an enormous, traditionally underserved industry.

Already backed by leading international VC investors, with its technology deployed into major enterprise customers, the business is scaling its engineering team and looking for outstanding engineers who want to make a real impact.

The Technology

- Frontend: TypeScript, React, Next.js

- Backend: Python, Node.js, Go

- AI: LLMs, Generative AI, AI-powered workflows and production AI systems

- Infrastructure: AWS, cloud-native architecture

You'll own complex product features end-to-end, from intuitive frontend interfaces through to backend services and data models, working directly with the founders and customers.

This isn't about building prototypes. It's about developing sophisticated, AI-powered software that solves difficult real-world problems and is already being used in production.

Who am I looking for?

- Strong full-stack engineering experience, with excellent frontend skills and the ability to work deeply across the backend.

- Experience building, shipping and scaling complex software products used by real customers.

- Exposure to AI/LLM-powered applications or a genuine interest in building production AI systems.

- Engineers who thrive in early-stage, high-growth environments, take ownership and enjoy solving difficult technical challenges.

- Founding Engineers, Product Engineers and Software Engineers who want to influence both the product and its technical direction.

If you're an ambitious engineer who wants genuine ownership, difficult technical problems and the opportunity to help build something significant, I'd love to hear from you.
