What you'll do

  • Contribute to Migration Work: Help execute the brownfield-to-greenfield React Native migration within our white-labeled, multi-brand application ecosystem.

  • Support Monorepo Scaling: Work within our React Native monorepo to support concurrent development across multiple squads, and help maintain shared npm packages used across mobile and web.

  • Strengthen CI/CD: Help maintain and improve our CI/CD pipelines in Bitrise, and contribute to the team's ongoing evaluation of a future Expo migration.

  • Build Test Automation: Design and extend end-to-end test coverage using Maestro, helping raise the bar for release quality and confidence across the app.

  • Improve Observability: Build and maintain tracing and dashboards in Honeycomb to help the team make data-informed decisions about app health.

  • Collaborate Across Squads: Partner with your Engineering Manager and teammates to review technical solutions and bring good engineering practices into your day-to-day work.

What they're looking for

  • Support Application Health: Help investigate and resolve production issues, contributing to a culture of stability and reliability.
  • Document Decisions: Write clear technical documentation — design proposals, ADRs, or lightweight write-ups — appropriate to the scope of the work.
  • Hands-on experience working with AI tooling (e.g., Claude Code, Cursor,: Copilot) beyond casual experimentation. You use AI agents every day. You have a practical sense of how the context you provide to AI tools shapes output quality, and how to set boundaries on AI-generated work.
  • React Native & Native Mobile Expertise: Deep, production-tested expertise in React Native, combined with strong knowledge of both iOS and Android. You understand React Native's internal mechanics, performance profiling, native code bridging, platform-specific features and constraints, as well as the respective app store release processes. You are comfortable working across the full mobile stack to build and scale enterprise-grade applications.
