Future - Senior or Staff Frontend Software Engineer

• Engineering Excellence- Set the standard for frontend code quality, component architecture, and design system usage across the team. Build for scale — write code that the next engineer can pick up, extend, and ship with confidence. Instrument the frontend for performance and reliability. Know when things break before members do. • Engineering Excellence- • AI as a Force Multiplier- Use AI to accelerate prototyping, code review, and documentation — then apply your judgment to sharpen the output. Bring a perspective on how AI can be woven into the member experience itself — personalization, intelligent UI, adaptive coaching flows. • AI as a Force Multiplier- • 5+ years of frontend engineering experience, with significant time on consumer-facing mobile or web products. • Deep expertise in React Native or React, TypeScript, and modern state management. • Strong design sensibility — you can work from a Figma file and know when something is off. • Production experience with Next.js (App Router, SSR/CSR tradeoffs, caching) • Solid understanding of rendering patterns (SSR/SSG/client), performance (memoization, avoiding unnecessary renders) state management (server vs client state separation) • Comfortable building clean UI from designs (spacing, layout, accessibility) • You've operated at the Senior or Staff level — or functioned at that altitude regardless of title. • Experience in a fast-moving startup where you've made smart tradeoffs between polish and velocity. • Use AI tools and coding AI Agents (Claude, Cursor, Codex) • Domain Passion You care about health, fitness, and the idea that great coaching can change people's lives. • Domain Passion • Working Style • High craft. You see the difference between good and great and you care about it. • Collaborative with design — you push back when something doesn't work and propose alternatives, not just problems. • Low ego, high ownership. You do what needs to be done. • Experience with health or wellness consumer apps. • Deployment experience on Vercel or Amazon Web Services. • Experience with monorepos (e.g. Turborepo/Nx) and multi-app setups • Familiar with BFF patterns (frontend talking to its own backend layer) • Strong testing habits (unit + e2e as part of delivery) • Experience building AI-powered or personalized product experiences. • Familiarity with performance optimization for mobile apps at scale.
