Senior Frontend Engineer

Blockworks is an information platform that sits at the center of the crypto industry. We transform raw, complex data and facts into actionable research, trusted news, alpha-driven insights, and world-class events. The result is transparency and confidence. We enable investors, operators, and institutions to see past the noise, make better decisions, and drive the industry forward.

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.

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

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.

Minimum qualifications:

• 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

You’ve built an open-source UI library, framework, or CLI tool. You write about frontend ideas, contribute to community projects, or tinker with new frontend infra before it’s mainstream. You treat performance like a feature and know how to debug jank, memory leaks, and hydration mismatches.

You’ve worked with web workers, service workers, or fine-grained performance optimizations in the browser. You understand how the frontend interacts with backend systems and enjoy tweaking data models when needed. You’re the person other engineers come to when they want to make their app “feel better.”

• You’ve built or contributed to an open source frontend framework or tool

• You’ve worked on high-performance, data-heavy UIs (e.g., dashboards, tables, charts)

• You know how to measure and improve Core Web Vitals

• You’ve used TanStack Query extensively (or similar libraries like SWR, Apollo)

• You’ve worked with design systems, component libraries, or headless UI

• You’ve shipped a product with web workers or did serious perf debugging
