Senior Frontend Engineer

### Who you are
- 3+ years building production web applications in React and TypeScript
- Strong understanding of rendering models (CSR, SSR, SSG, hydration)
- Experience working on performance-sensitive surfaces
- Working knowledge of Core Web Vitals and frontend performance fundamentals
- Familiarity with technical SEO concepts (indexability, structured data, crawl behavior)
- Comfort navigating existing codebases and shipping independently
- Experience directing AI agents for frontend-specific work (rendering strategies, SEO patterns, Core Web Vitals optimization) is a strong signal
- Willingness to work across web and mobile surfaces when needed
- Experience with Astro or other mixed-rendering frameworks (Next.js, Remix, etc.)
- Experience with React Native
- Exposure to native iOS or Android development
- Marketplace, e-commerce, or high-traffic consumer product experience
- Experience working in experimentation-heavy environments

### What the job involves
- We are looking for a web-first Frontend Engineer who cares deeply about performance, rendering strategy, and building fast, discoverable user experiences
- This role is primarily focused on React web development within a mixed-rendering environment (React SPA + Astro)
- You'll contribute to improving Core Web Vitals, search performance, and feature velocity — while operating in an AI-augmented development environment (L3+/AI-first) where agents are part of daily workflows
- Web (Primary Focus):
- Build and ship production features in React (legacy SPA) with TypeScript
- Contribute to our Astro-based static and mixed-rendering architecture
- Implement performance optimizations that improve Core Web Vitals (LCP, CLS, INP)
- Apply technical SEO best practices within features (rendering behavior, metadata, structured data, crawl-safe patterns)
- Work within SSR, SSG, and hydration constraints — understanding tradeoffs and execution details
- Cross-Platform Contribution:
- Contribute to shared features in React Native when functionality overlaps with web
- Move features cross-platform when appropriate rather than relying on handoffs
- Collaborate with mobile engineers on platform-specific adjustments
- Contribute to performance-sensitive areas, including occasional native integrations as our tooling evolves
- Engineering Culture:
- Use AI agents for component generation, test writing, and performance optimization — our mixed-rendering architecture involves a lot of SSR/SSG scaffolding and rendering validation that benefits from agentic coding
- Participate in code reviews and architectural discussions
- Ship iteratively with a strong bias toward measurable performance impact
