Senior AI-First Mobile App Developer (Contract, Remote)

We are hiring a senior mobile app developer to lead the build of a new consumer mobile product from MVP through launch. This is a hands-on contract role for someone who can move quickly, work independently, and use modern AI-assisted development tools as a core part of their workflow. Because this role will involve confidential product information, shortlisted candidates will be required to sign a non-disclosure agreement before full product details, workflows, and technical specifications are shared. Role Overview This role is ideal for a builder who is comfortable owning execution across frontend, backend integration, and release preparation for a mobile app. We are specifically looking for a developer who already uses AI coding tools such as Cursor, Claude Code, and similar platforms to accelerate development, debugging, refactoring, documentation, and testing. The right candidate should be able to take a product from scoped requirements to a functional production-ready application, using AI tools intelligently without sacrificing code quality, architecture, security, or maintainability. Key Responsibilities Build and ship a full mobile application for iOS and Android. Own day-to-day implementation across core app features, API integrations, data flows, and release readiness. Use AI coding tools in a practical, high-output way to speed up development while maintaining strong engineering judgment. Translate product requirements into clean technical architecture and execution plans. Write production-quality, maintainable, well-structured code. Set up and improve development workflows, including debugging, code reviews, testing, and documentation. Collaborate with product and stakeholder teams to clarify scope, timelines, risks, and tradeoffs. Identify blockers early and propose solutions quickly. Help define the MVP build path, technical decisions, and launch priorities. Support deployment, bug fixing, QA handoff, and app store submission readiness. Required Qualifications Strong experience building and shipping full mobile applications from scratch. Ability to develop a complete app, not just isolated tickets or UI components. Proven proficiency with AI-assisted coding tools such as Cursor (main tool), Claude Code, GitHub Copilot, or similar. Strong judgment around when to rely on AI-generated code and when to manually architect or refine solutions. Experience working across frontend application logic, backend/API integration, authentication, state management, and performance optimization. Solid understanding of software architecture, debugging, version control, and testing practices. Ability to read, evaluate, and improve code generated through AI workflows. Strong communication skills and comfort working in a fast-moving, async remote environment. Preferred Background Experience building cross-platform mobile apps using frameworks such as React Native, Expo, or Flutter. Experience shipping consumer subscription apps or data-driven mobile products. Familiarity with analytics, push notifications, third-party integrations, and production monitoring. Experience building secure applications with privacy-conscious engineering practices. Previous experience as a lead developer, founding engineer, or highly autonomous senior contractor. Recommended Tech Stack The stack below reflects our current preferred direction. Candidates do not need deep expertise in every tool listed, but should be comfortable working within a modern TypeScript-based mobile stack and making sound technical decisions across the full product lifecycle. Mobile: React Native + Expo, TypeScript, Expo Router, Zustand + TanStack Query, NativeWind or Tamagui, React Hook Form + Zod, Victory Native or similar charting libraries, React Native Reanimated, Expo SecureStore + MMKV, WatermelonDB or SQLite-based local storage, Expo Notifications, Expo Linking, Sentry React Native, and PostHog React Native. Backend / API: Node.js, Next.js API routes or Hono, TypeScript across the full stack, tRPC, Supabase Auth, PostgreSQL, Drizzle ORM, Zod for shared validation, Inngest or Trigger.dev for background jobs, Supabase Storage, and Resend, SendGrid, or similar transactional email tooling. AI / Developer Workflow: Cursor (main tool), Claude Code, GitHub Copilot or comparable AI-assisted development tools, Anthropic Claude and OpenAI APIs or comparable LLM integrations, plus prompt/version management and AI observability tooling where appropriate. Infrastructure / DevOps: Render, Supabase, GitHub Actions, Expo EAS Build / Submit, Sentry, Better Stack or similar monitoring tools, and Cloudflare or a comparable CDN / security layer. Product / Operations: RevenueCat, PostHog, ClickUp, Slack, Figma, and Notion or equivalent documentation tooling. What We’re Looking For Fast execution without sloppy code. Strong product instincts, not just technical output. Comfort using AI as a serious development multiplier. Someone who can turn ambiguous requirements into shipped software. Someone who understands how to balance speed, quality, and pragmatism in an MVP environment.
