Senior Mobile Engineer — React Native + AI-Driven Dev

Jobtailor; Denver (CO); On-site; USD 120,000 - 180,000; Full time

Job summary

ServiceCore is seeking a senior mobile engineer to own the architecture and implementation quality of our mobile apps, focusing on offline-first data handling, performance, and UI responsiveness.

You will drive testing strategy, reduce mobile tech debt, mentor junior engineers, and partner with Product and Design on UX decisions while advancing AI-assisted development with Cursor and Copilot.

Qualifications

• 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: 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.

Responsibilities

• 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; raise the team’s mobile capability, not just your own.
• Partner with Product and Design on UX decisions that have technical implications — be 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.
