We're building Folio AI — the next generation commerce engine for millions of businesses. This is a core engineering role. Your first mission: own our mobile apps. But this isn't a siloed mobile role — you'll work across the stack, from mobile clients to backend systems and APIs, wherever the hardest problems are. We're a small team, so boundaries between roles are thin. What matters is that you can go deep on hard technical problems and ship production systems that work. You'll: → Own and evolve our mobile apps — iOS and Android → Work across backend systems, APIs, and infrastructure as the product evolves → Design systems that are reliable, fast, and ready to scale → Work closely with the team to evolve the product architecture We're looking for someone who: → Is a strong engineer first — can think in systems and reason about architecture → Has solid mobile development experience across iOS and Android → Swift experience is a plus — our iOS app is already in production → Has shipped real products, ideally across mobile and backend → Has adopted AI into their workflow — and actually enjoys it You won't just be a "mobile developer." You'll be an engineer on a small team where what you build defines the product. Early team, London-based. High ownership. Real impact. If this sounds like you — reach out.
