Join a stealth startup using AI to revolutionise how people shop online

We're partnered with a well-funded startup building out their Founding Engineering Team. They're combining AI and commerce to eliminate the overwhelm of multi-item purchasing decisions.

Backed by notable investors and angels their personal shopping assistant is tackling real consumer pain points - think preparing for a baby, setting up for university, or any complex buying journey where choice paralysis kicks in.

With an MVP already testing with users and launch planned for July/August, they're at that sweet spot of proven concept with serious funding to scale.

We're looking for Senior level Software Engineers with the ambition to join a Founding team and help build the future of AI-powered commerce from the ground up.

You'll be instrumental in building consumer-facing AI products that actually work, shaping their architecture, tooling, and culture from day one. This is a unique opportunity to work hands-on with conversational AI, recommendation systems, and collaborative shopping experiences in a fast-moving, mission-driven environment.

Why this role stands out:

• You'll be foundational team member with extensive funding runway
• Direct impact on product development from prototype to product-market fit
• Combine cutting-edge AI with real consumer commerce problems
• The tech challenges are greenfield: ML-driven personalization, collaborative features, and scalable commerce infrastructure

The early stage means huge room for career progression with opportunities to lead technical decisions, define system architecture, drive experimentation, and work closely with real users providing feedback. The founders are experienced operators who've been through the 0-1 journey before and know how to build products people love.

Tech Stack: Primarily C#/.NET and Azure, Python for data work, Go microservices, React Native/TypeScript mobile frontend. They're open to engineers from any language background, especially if you have strong opinions about the stack, and want to influence technical decisions.

Package: £90k-£120k + equity worth 80% of salary (1-year cliff, 4-year vesting).

Location: Central London, 2-3 days a week, core hours 10am-4pm with lunch provided on office days.
