What We're Looking For

We’re hiring a hands-on Senior Engineer with deep React Native experience to own and evolve high-impact mobile features across iOS and Android. You’ll be a TypeScript expert focused primarily on our React Native application, contributing to mobile architecture, performance, and reliability.

This is a senior individual contributor role - you’ll write production code daily, mentor engineers within the mobile team, and partner closely with Product and Design to deliver high-quality customer experiences.

What You'll Do

End-to-End Delivery

  • Own and deliver complex React Native features from technical design through production release across iOS and Android that support a growing user base, evolving product requirements, and real-world mobile constraints.
  • Write clean, maintainable, and well-tested TypeScript code with strong attention to performance and user experience.
  • Troubleshoot and resolve production issues, including crashes, regressions, and platform-specific edge cases.

Mobile Architecture & Technical Design

  • Contribute to scalable mobile architecture decisions, including state management, navigation, API and tool integrations, and feature modularization.
  • Improve codebase maintainability by reducing technical debt and promoting reusable, well-structured components.
  • Apply performance, accessibility, and platform best practices to deliver smooth, consistent user experiences.

Developer Experience & Reliability

  • Improve team-level mobile workflows, testing practices, and release processes.
  • Instrument applications with meaningful logging, monitoring, and crash reporting.
  • Participate in incident response and contribute to root cause analysis and preventative improvements.

Collaboration & Technical Leadership

  • Mentor junior and mid-level engineers through thoughtful code reviews and design discussions.
  • Partner closely with Product and Design to translate requirements into scalable mobile solutions.
  • Identify technical risks early and communicate clear tradeoffs between speed, quality, and long-term maintainability.

What You Bring

  • 8+ years of professional software engineering experience, including 3+ years of hands-on React Native mobile development.
  • Strong expertise in TypeScript and modern React patterns.
  • Deep experience shipping production React Native apps across iOS and Android.
  • Experience with state management libraries (e.g., React Query, Zustand or similar).
  • Proficiency in working within the Expo ecosystem
  • Experience in building and integrating custom native modules.
  • Proven ability to optimize mobile performance (rendering, memory usage, startup time).
  • Experience with mobile CI/CD pipelines, app store release processes, and crash monitoring and observability tools.
  • Strong understanding of UI/UX best practices, mobile security fundamentals, error handling, logging, and data persistence.
  • Demonstrated mentorship experience and strong communication skills.

Nice to Have

  • Experience with Kotlin, Compose Multi Platform
  • Experience contributing to web frontends (e.g., Next.js, TypeScript).
  • Experience working in retail or marketplace platforms with real-time inventory, store-level operations, and high-volume, rapidly changing data.

What We Offer

  • Competitive salary, equity, and comprehensive benefits.
  • 100% remote work with flexibility and trust.
  • Mission-driven work that reduces food waste and expands access to affordable food.
  • A fast-growing, collaborative team with big ambitions.
  • Real opportunities for career growth and professional development.
