  • A good eye for UI/UX, with experience in Figma or similar tools
  • Experience publishing and maintaining apps on the App Store and Google Play
  • Comfortable working independently in a fast-moving startup, with lots of ownership
  • A clear communicator who enjoys working with non-technical foundersExperience with in-app subscriptions, paywalls and tools like RevenueCat
  • Experience with analytics and A/B testing (Firebase, Mixpanel, Amplitude)
  • Experience with AI or LLM integrations
  • Familiarity with Islamic practices, or an interest in faith-based products


What you get


  • £38,000 - £42,000 per annum, depending on experience
  • Real ownership of the product and technical direction from day one
  • The chance to build something that matters to millions of people
  • Visa sponsorship for the right candidate
