Company Description
Kiki Club is a London-based, invite-only sublet marketplace that has raised $5.5M from Blackbird and executives from Airbnb and Facebook.

Job Description
As the third founding engineer, you will own the entire tech stack alongside two others, building an AI-centric marketplace that optimizes trust over transactions. You'll ship critical iOS features using React Native and architect systems powered by proprietary social data, directly impacting Kiki’s mission to unchain one billion people from their rent.
Location
London, UK
Why this role is remarkable
- Join a high-growth startup backed by Blackbird and world-class angels from Airbnb, Uber, and Canva, with two years of runway and $4.7M gross ARR.
- Experience true founding-level ownership, setting the technical foundations for a product growing 3x faster in London than its previous NYC market.
- Work in a culture that treats AI as a core productivity multiplier, allowing a small team of six to achieve outsized global impact.
What You Will Do
- Own the end-to-end development of the iOS app using React Native, shipping features like in-app messaging and interactive map search.
- Architect and build an AI-driven "mutual friend" layer using a proprietary dataset of over 10,000 social conversations to verify user trust.
- Collaborate directly with the founders in-person at Shoreditch Exchange to evolve the tech stack across React, TypeScript, Postgres, and AWS.
The ideal candidate
- A senior full-stack engineer with high shipping output and a deep proficiency in TypeScript, React Native, and modern cloud infrastructure.
- An engineer who treats AI coding tools as a central, indispensable part of their development workflow to maximize speed and quality.
- A first-principles thinker who can navigate vague requirements to build real products, possessing strong design judgment and a low attachment to specific implementations.
