What they're looking for

• Strengthen Application Health & Reliability: Lead technical efforts to improve application health and reliability by designing observability tooling, performance reporting, incident response practices, and operational guardrails that improve system stability.
• Pragmatic Technical Governance: Facilitate architectural decision-making, choosing the appropriate level of documentation—from lightweight design proposals to formal RFCs and ADRs—based on the scope and impact of each initiative.
• 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.
• Agentic Engineering: Hands-on experience using AI coding agents (Claude Code, Cursor, Copilot) in production or near-production work. You think beyond prompts to context engineering—structuring specifications, tool configurations, and information flow so agents produce reliable output. You can decompose complex workflows across agentic components, identify unreliable outputs, and introduce the appropriate guardrails where needed.
