Senior Front End Engineer

Wagmo•New York, NY

7d•$180,000 - $210,000

About The Position

We are hiring a Senior Front End Engineer to help us modernize and consolidate our front end stack at a pivotal moment. You’ll play a hands-on role completing our migration to a Turborepo-based architecture, building shared component libraries, porting our mobile app to React Native, and integrating our CMS — all while shipping features that directly improve the lives of pet parents and the employers who support them. You bring deep expertise in React and TypeScript, care about component quality and developer experience, and thrive in a fast-moving environment where you can make meaningful architectural calls. You’ll partner closely with Product, Design, and Back End Engineering, and you’ll help raise the bar for how we build across web and mobile.

Requirements

5+ years of front end engineering experience, ideally at a high-growth SaaS or consumer tech company
Expert-level React and TypeScript skills
Experience with monorepo tooling (Turborepo, Nx, or similar) and building shared component libraries
Familiarity with React Native and a willingness to own cross-platform mobile development
Comfort working with headless CMS tools (builder.io experience a plus)
Strong understanding of modern front end architecture: routing, state management, API integration, performance optimization, and error handling
Experience with CI/CD, Git, and automated testing
Strong communicator who can lead projects, collaborate cross-functionally, and work with Product and Design without hand-holding
Autonomous and high-ownership; comfortable making calls under ambiguity in a fast-moving environment

Responsibilities

Complete and own the migration of our logged-in dashboard (webclient) to our monorepo architecture, including page routing, component migration, form mutations, and phased cutover.
Build and grow a shared component library that works across web and mobile surfaces, enabling faster, more consistent product development.
Lead the port of our mobile app from Flutter to React Native, establishing a unified codebase and significantly improving cross-platform feature velocity.
Integrate builder.io more deeply into our stack to enable CMS-managed content across dashboard pages, the quiz, and FAQs — reducing the need for engineering involvement in content changes.
Implement robust error handling, idempotency patterns, and Sentry hygiene across the front end to improve reliability and reduce noise.
Partner with Back End Engineering to migrate the front end off V1 API endpoints onto clean V2 APIs as we modernize our back end.
Drive front end best practices: code quality, testing, CI/CD, and documentation.
