Senior Product Engineer, Front-End

Role: Senior Product Engineer, Front-End

Senior front-end engineer responsible for taking product work from idea to production. You’ll own real product outcomes—defining the problem, making tradeoffs, building the UI, and continuously improving after launch.

Responsibilities

• Build and improve customer-facing product experiences in a large SPA.
• Partner with product and backend engineers to define solutions and shape GraphQL APIs.
• Turn complex B2B workflows into clear interfaces (e.g., pricing, approvals, permissions, integrations).
• Write maintainable, accessible front-end code with a strong focus on performance and usability.
• Create reusable components and patterns to keep UI consistent across the application.
• Improve quality using testing, observability, and better front-end tooling.
• Investigate and resolve production issues when they arise.
• Support other engineers via code reviews, pairing, and constructive feedback.
• Measure and improve performance using profiling, bundle analysis, route-level loading strategies, and real-user metrics (Core Web Vitals).

Examples of Work

• Migrate legacy Web Forms features into a modern React + TypeScript SPA using Vite and TanStack Router.
• Build and maintain a shared component library using Panda CSS and React Aria (accessible primitives, tokens, documentation).
• Standardize GraphQL query/mutation patterns, code generation, caching, and error handling.
• Ship features integrating external systems (e.g., payments, notifications, shipping updates).
• Triage customer-reported bugs: reproduce, fix, add test coverage, and close the loop.
• Build internal tools for support/account teams to diagnose issues and take safe administrative actions.

Requirements

• Experience shipping frontend-heavy SaaS products in production.
• Strong JavaScript and TypeScript skills; deep experience building large React SPAs.
• Hands-on modern frontend tooling/architecture, ideally including Vite and TanStack Router/Query.
• Strong CSS and component architecture experience (e.g., Panda CSS, React Aria).
• Solid GraphQL experience: queries, mutations, code generation, and client-side state/caching.
• Frontend testing experience (e.g., React Testing Library, Playwright).
• Familiarity with CI/CD and modern frontend delivery practices.
• Practical cloud experience, ideally AWS.
• Clear communication, sound judgment, and collaborative style.
• Familiarity with secure front-end patterns for permissions/authentication/data handling and safe admin tooling.

Nice to Have

• GraphQL schema design and/or performance tuning.
• Experience with design systems or shared component libraries.
• Strong accessibility knowledge (including WCAG 2.2 AA, semantic HTML, keyboard accessibility).
