Responsibilities
- Shape architectural direction and contribute to the execution of brownfield-to-greenfield React Native migration within a white-labeled, multi-brand application ecosystem.
- Design and evolve the long-term scalability and developer experience of the React Native monorepo, enabling seamless concurrent development for 50+ mobile engineers across multiple squads.
- Maintain and scale the monorepo to host shared npm packages designed for future cross-platform code sharing with web repositories.
- Maintain and optimize current CI/CD pipelines in Bitrise while helping shape future migration to Expo.
- Enable product teams to make data-informed decisions by building robust tracing and dashboards in Honeycomb. Help establish and scale end-to-end testing frameworks using Maestro.
- Partner with Engineering Managers and Product stakeholders to review technical solutions, provide architectural guidance, and promote engineering best practices.
- Lead technical efforts to improve application health and reliability by designing observability tooling, performance reporting, incident response practices, and operational guardrails.
- Facilitate architectural decision-making, choosing the appropriate level of documentation—from lightweight design proposals to formal RFCs and ADRs.
- Contribute to the app experience, owning metrics that reflect quality for mobile customers (retention, crash-free sessions, conversion).
- Work beyond specialization when the problem demands it.
- Operate what you build: instrument, monitor, and improve systems in production.
Requirements
- Hands-on experience working with AI tooling (e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. Use AI agents daily.
- Deep, production-tested expertise in React Native, combined with strong knowledge of both iOS and Android. Understand React Native's internal mechanics, performance profiling, native code bridging, platform-specific features and constraints, and app store release processes.
- Hands-on experience using AI coding agents in production or near-production work. Think beyond prompts to context engineering—structuring specifications, tool configurations, and information flow so agents produce reliable output.
- Proven track record of managing and optimizing workflows, linting, caching, and build times for large engineering teams.
