About the role

Key responsibilities & impact

Design, develop, test, and deploy features across responsive web and React Native (including React Native Web) mobile applications used by pet parents.
Own end-to-end delivery of product areas, including technical design, implementation, code review, deployment, and post-release monitoring.
Translate product requirements and UX designs into clean, performant, accessible, and maintainable front-end code.
Work day-to-day in the team's foundational toolchain — Git/GitHub for version control and CI/CD triggers, Node.js, VS Code, GitHub Codespaces for containerized development, GitHub Copilot Enterprise for AI-assisted coding, Expo CLI, Azure CLI, Postman for API testing, React DevTools, and BrowserStack for cross-device/browser validation.
Build and maintain reusable, accessible UI components using a utility-first styling approach (e.g., Tailwind/NativeWind) and component patterns adapted for React Native (e.g., shadcn/ui-style component libraries), and manage typography/font loading consistently across web and mobile.
Integrate with backend APIs, manage application state effectively, and optimize for performance on web and mobile.
Implement secure authentication and identity flows, and handle customer data in line with security and privacy standards.
Write unit, integration, and end-to-end tests; participate in code reviews to uphold engineering standards.
Contribute to CI/CD pipelines, mobile release processes, and incident response for customer-facing services.
Partner with designers and product managers to refine requirements, evaluate trade-offs, and shape the user experience.
Mentor mid-level and junior engineers through pairing, code reviews, and design discussions.
Identify technical debt and performance issues, and lead targeted improvements with measurable customer impact.
Stay current with the React and React Native ecosystem and apply new tools and patterns where they add value.

Strong skills in modern styling and UI development — utility-first CSS frameworks (Tailwind/NativeWind), component patterns (shadcn/ui-style libraries for React Native), and managing fonts and typography across platforms.
Solid understanding of modern state management patterns, RESTful API integration, and component-driven architecture.
Experience with the mobile app lifecycle, including build configurations, app store submission, and over-the-air updates.
Proficiency with CI/CD tools and automated testing frameworks (unit, component, and end-to-end).
Experience implementing authentication flows (OIDC/OAuth2 or equivalent) and handling tokens securely.
Familiarity with accessibility, performance tuning, and modern web/mobile security practices.
