Job description

Responsibilities

• 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.

Requirements

• Bachelor’s degree in Computer Science, Software Engineering, or related field (equivalent experience considered)
• Engineering experience building production web or mobile applications.
• Strong proficiency in JavaScript and TypeScript, with hands‑on production experience in React; React Native (including React Native Web) experience strongly preferred.
• Hands‑on proficiency with the foundational developer toolchain: Git/GitHub, Node.js, Next.js, VS Code, React DevTools, Postman, Expo CLI, Azure CLI, and BrowserStack.
• Hands‑on experience building Backend‑for‑Frontend (BFF) services and Web APIs in .NET (C#) to support customer‑facing web and mobile experiences.
• Comfort working in containerized development environments (e.g., GitHub Codespaces) and using AI‑assisted development tools (e.g., GitHub Copilot Enterprise).
• 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.
• Strong collaboration skills and the ability to work effectively with product, design, and back‑end engineering partners.
