About the Role

ServiceCore builds the software that runs the portable sanitation and liquid waste industry. Our field technicians — drivers, service crews, route runners — live in our mobile app. It’s how they receive jobs, complete inspections, capture signatures, and communicate issues back to the office in real time. The Senior Software Engineer (Mobile) owns the technical quality and direction of that experience.

You’ll be the mobile authority on a small, cross-functional pod — setting the architecture, leading React Native development, mentoring less experienced engineers, and partnering closely with Product and Design to build something field workers actually want to use. You’ll participate in customer discovery so your technical decisions stay grounded in how real people work in the field, not just what looks clean in a spec.

Our mobile stack is React Native running in Expo. The backend is PHP Laminas Framework with MySQL on AWS. We work fully remote, come together once a year as a company, and do quarterly planning as a team. Hybrid option available if you’re near Denver, CO.

What You'll Do

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.

What We're Looking For

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

Who Thrives Here

ServiceCore’s values are: Love Our Customers, Give a Shit, Deliver Results, Be Real, and Keep It Fun. The mobile app is the most visible product to our field workers — when it’s slow or broken, someone’s job gets harder. Engineers who do well in this role take that personally. They care about UX not as a concept but because a driver using the app at 6am in the cold deserves something that just works. They give direct feedback, own outcomes without being asked twice, and make the team around them better. If that’s how you approach the work, you’ll fit right in.
