Senior Frontend Engineer, Blockworks

• You’re a frontend native who obsesses over both pixels and performance. You build intuitive interfaces with craft and care - balancing speed, polish, and maintainability without sacrificing one for the other
• You don’t wait for a designer to hand you a Figma file - you sketch things yourself, ship fast, and polish in prod
• You’re energized by ambiguity and love shipping v1s. You’re relentlessly curious and always exploring what’s next in frontend: AI copilots, frameworks, build pipelines, performance tricks, p75 optimization
• You know when to use Tailwind and when to write raw CSS. You don’t just write React - you bend it to your will
• Experimentation is frequent at Blockworks. Comfortability with being uncomfortable is a must
• You’ve built and shipped multiple frontend-heavy products at scale - ideally in SaaS or data-heavy domains. You know the pitfalls of bloated JS bundles, stale queries, and layout thrashing - and you know how to avoid them. You’ve made tough architectural decisions before and can defend them
• You have at least 5 years of professional experience focused on frontend engineering, with deep experience in React and ideally Next.js. You’ve worked with component libraries, SSR/SSG strategies, and modern bundlers. You’ve owned projects and aren’t afraid to push back or run with vague requirements
• 5+ years experience in frontend engineering
• Deep expertise with React and production-grade Next.js apps
• Experience deploying to Vercel or similar JAMstack platforms
• Strong grasp of async data fetching, caching strategies, and rendering performance
• Fluent in modern TypeScript

Desirable

• You’ll join the frontend team at Blockworks and help us ship best-in-class user interfaces across our crypto research platform, data dashboards, and public media sites. You’ll work closely with design, product, and backend to own complex frontend projects end-to-end—from architecture and data fetching to accessibility and animation
• We ship fast, we ship often, and we love people who can take an idea and bring it to life without hand-holding
• Build and ship React/Next.js apps to Vercel with high-performance and great UX
• Create beautiful, intuitive interfaces without relying on detailed specs
• Use Tailwind, Chakra, or raw CSS to build reusable and accessible UI components
• Optimize rendering performance using techniques like memoization, lazy loading, web workers, etc
• Write clean, maintainable code that scales across multiple frontend apps
• Own data-fetching layers with TanStack Query (React Query), including caching, pagination, prefetching
• Leverage AI tools to accelerate coding, testing, refactoring, and UI prototyping
• Collaborate directly with backend engineers, data engineers, data analysts, and leadership to shape the product
• Contribute to static builds and SSR/ISR pipelines on Vercel
