Staff Frontend Engineer

Role Overview

Staff Frontend Web Application Engineer (Staff Frontend Engineer) at TeamSnap, joining a fully distributed engineering team to build and optimize high-performance web applications for youth sports workflows.

Responsibilities

• Design, build, and optimize high-performance TypeScript & React SPAs backed by RESTful APIs
• Collaborate with Product and Design to extend and evolve a design system (reusable, accessible components, theming, tokens, responsive patterns)
• Advocate modern frontend practices: type safety, component-driven architecture, responsive layouts, performance (e.g., lazy loading, caching)
• Partner cross-functionally (backend, mobile, QA, product) to define API behavior, specs, architecture, and ensure end-to-end quality
• Mentor and level up engineers via code reviews, pairing, leading the web guild, and improving frontend craft
• Ensure reliability through unit, integration, and E2E testing; integrate with CI/CD; rotate on-call to resolve incidents
• Lead projects to improve coding practices/principles, build performance, test infrastructure, and CI/CD workflows
• Evaluate and adopt AI-driven tooling (code generation assistants, refactoring bots, LLM-based test generation) to boost velocity and quality
• Explore emerging frontend technologies (e.g., micro-frontends) and provide data-driven recommendations

Requirements

• 8+ years building production-scale web applications with React and advanced TypeScript (modern toolchains like Vite/Webpack)
• 2+ years in a Staff/Tech-Lead role shaping frontend vision, driving standards, and mentoring senior engineers
• Strong experience integrating REST services and managing complex UI state with tools such as Context API, Redux, Zustand, or equivalent
• Experience architecting/extending component libraries/design systems with responsive, mobile-first emphasis and design tokens/theming
• Proven delivery with automated tests (unit/snapshot/E2E), CI/CD configuration, and use of observability to measure performance/error rates
• Comfortable shaping RESTful APIs with backend teams (type-safe data contracts, async state handling)
• Strong communication skills: constructive feedback, mentoring, influencing cross-team alignment, articulating technical trade-offs

Bonus / Nice to Have

• Micro-frontend architectures and/or SSR frameworks
• Performance profiling (Lighthouse, Web Vitals) and advanced caching/CDN strategies
• Experience using AI assistants/code-generation/LLM services to streamline development tasks
