What We're Looking For

• 0–4 years of experience
• Product-oriented full-stack mobile development experience
• Experience with React Native, Swift, Kotlin, or similar technologies
• Experience with Next.js and Tailwind
• Experience with backend-as-a-service platforms; Supabase is strongly preferred
• Familiarity with authentication, payments, database design, and APIs
• Strong product and design intuition
• Strong first-principles problem solving
• Ability to work independently and own the mobile product end to end
• Comfortable working with modern development practices and AI coding tools
• Strong ability to move quickly from specifications and designs to production

Nice to Have
