About Kiki Club London
Kiki is an invite-only sublet club helping people who’ve never sublet before earn money from their home while they travel. We’re not really a property company. We’re solving a deeply human problem: how do you trust a stranger enough to let them stay in your home? Our answer is community. Everyone on Kiki is a friend of a friend, and we show you exactly how you’re connected.
Over 7 years and 4 countries (New Zealand, Sydney, New York and now London), we’ve matched over 13,000 people and earned hosts over $6.3M USD. We raised our seed from Blackbird, the biggest VC in Australasia, plus angels who were execs at Airbnb, Facebook Marketplace, Uber, Turo, Bumble and Canva. After being the first startup in our space to get sued by New York, we moved to London in 2025, and it’s now our fastest-growing city ever: 2,650+ matches in 13 months, $4.7M gross ARR, and all of it through word of mouth.
Next, we’re building an AI-centric marketplace that acts like your mutual friend, surfacing every connection between two people so they can trust each other, powered by 10,000+ real conversations with our users that no one else has.
We’re a small, close-knit, AI-first team working in person 5 days a week in Shoreditch. We work hard, celebrate every win, and look after ourselves along the way.
What you will do
- Ship core features for the recently launched React Native iOS app, including interactive map searching, in-app messaging, and a complex trust-visualization layer.
- Collaborate directly with the founding engineering team to architect an AI-centric marketplace powered by proprietary social data to facilitate seamless subletting.
- Maintain a high-velocity output across the full stack while utilizing AI coding tools to optimize the software development lifecycle from writing to testing.
Who this is a fit for
- Strong generalist with deep full-stack experience in React Native, TypeScript, and Node.js, prioritizing rapid shipping and high-quality output over years of tenure.
- First-principles thinker who treats AI coding tools as a core part of their architecture and review process, aiming for maximum productivity and efficiency.
- Independent operator who can navigate unfamiliar codebases quickly, communicate effectively in async environments, and turn vague product ideas into polished user experiences.
