Senior Software Engineer, Mobile (React Native)

The Role

We're looking for a Senior Software Engineer to become the primary owner of our mobile application, the core experience used by thousands of workers every day. You'll inherit a mature, production React Native codebase and take responsibility for its architecture, quality, and direction.

This is a high-ownership role. You won't be the only person touching mobile, but you'll be the one setting the standard: defining best practices and raising the bar in code review. You'll work across the stack where it helps you ship, partnering closely with product, design, and backend.

What You’ll Do

• Own the architecture, quality, and direction of our React Native apps.
• Hold the technical bar for mobile through code review, standards, and mentoring.
• Run the release process end-to-end, including App Store and Play Store listings.
• Turn ambiguous product problems into intuitive, high-quality experiences alongside product and design.
• Ship features from architecture through deployment and iteration.
• Drive improvements in performance, reliability, observability, and developer experience.
• Contribute across the stack, including React web and backend services.

We’re Looking For

• 5+ years building and shipping production software.
• Deep React Native expertise, including apps you've taken to scale in production.
• Strong command of React and TypeScript.
• A track record of raising the bar on a team: setting standards, reviewing code, mentoring engineers.
• Comfort working across the full stack and designing/consuming APIs.
• Strong product instincts and a bias toward shipping.
• A clear communicator who collaborates well and thrives in startup ambiguity.

Bonus Points

• Experience with marketplace, logistics, scheduling, or consumer products.
• Experience with mobile performance optimization and observability.
• Familiarity with Django, GraphQL, PostgreSQL, or AWS.
• Startup experience and a track record of owning products from zero to one.

Why Reflex?

• Real ownership: you'll own the mobile surface outright, not a slice of it.
• Early-stage upside: meaningful equity and a seat at the table as we scale.
• A team worth joining: high-ownership, low-ego, and serious about craft
