Job description

Established in 2021, Independence Pet Holdings is a corporate holding company that manages a diverse and broad portfolio of modern pet health brands and services, including insurance, pet education, lost recovery services, and more throughout North America.
We believe pet insurance is more than a financial product and build solutions to simplify the pet parenting journey and help improve the well-being of pets. As a leading authority in the pet category, we operate with a full stack of resources, capital, and services to support pet parents. Our multi-brand and omni-channel approach include our own insurance carrier, insurance brands and partner brands.
Job Summary
We are seeking a Senior Engineer to design, build, and ship high-quality features across our customer-facing web and mobile platforms. Reporting to the Senior Director, Customer Web and Mobile Experience, this role is a senior individual contributor who partners with product, design, and platform teams to deliver delightful pet parent experiences using React and React Native. The Senior Engineer takes ownership of meaningful product areas, mentors mid-level engineers, and contributes to the technical direction set by the Principal Engineer and engineering leadership.
Job Location: Chicago
Reports To: Senior Director, Customer Web and Mobile Experience
Main 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.

Required Qualifications
  • 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.

Preferred Qualifications
  • Experience with the Expo ecosystem (Expo SDK / Expo CLI) and unified mobile + web codebases.
  • Experience contributing to or maintaining a shared design system or component library.
  • Experience working with cloud platforms and the Microsoft ecosystem (Azure, Dynamics 365) and/or EIS Suite.
