About the role

Key responsibilities & impact

Own the architecture and implementation quality of ServiceCore’s mobile application — from offline-first data handling through device performance through UI responsiveness.
Set the testing strategy for mobile: device coverage, integration points with the API, and how to keep the suite maintainable as the app grows.
Drive mobile-specific technical debt reduction — identify what’s slowing the team down, make the case, and lead the fix.
Mentor SE1s and SE2s on your pod through code review, pairing, and direct feedback; you raise the team’s mobile capability, not just your own.
Partner with Product and Design on UX decisions that have technical implications — you’re an active voice in what gets built and how, not just an implementer.
Lead AI-assisted development on your team using tools like Cursor, Copilot, and agentic workflows to increase throughput and help your teammates do the same.

Requirements

What you’ll need

5+ years of professional mobile development experience — this is the hard floor; we need someone who has shipped and maintained real mobile apps at scale.
Strong proficiency in React Native — you’ve built and shipped production React Native apps, not just prototypes.
Solid TypeScript and React fundamentals; you write clean, maintainable component and state management code without leaning on magic.
Solid understanding of mobile-specific concerns: offline sync, push notifications, device performance, background tasks, and app store deployment.
Hands-on experience with AI-assisted development tools (Cursor, GitHub Copilot, or similar) as a real part of your workflow.
Demonstrable ability to architect mobile systems: you’ve made hard decisions around data sync strategies, caching, and state management — and you can explain the tradeoffs.
Track record of mentoring more junior engineers and improving the technical quality of the team around you.
Comfort engaging with the ‘why’ behind features — you participate in product conversations, not just sprint tickets.
Bonus points for: Experience with Expo or bare React Native workflow in a production app
Native module bridging experience (iOS/Android)
Experience building field service, logistics, or operations apps used in low-connectivity environments
Familiarity with the backend stack: PHP, MySQL, AWS
Experience with agentic AI workflows or building LLM-powered tooling.
