Senior Full Stack Javascript Engineer, WalletConnect

• This is a great opportunity for someone who thrives in a fast-moving, product-driven environment and enjoys working across the stack — from UI to API — to deliver developer-facing products used across the Web3 ecosystem
• This role suits an engineer who enjoys shipping quickly and seeing their work used by thousands of developers
• 5+ years of experience as a Full-Stack or Frontend Engineer building production-grade applications and/or SDKs
• Strong expertise with TypeScript, React/Next.js, and Node.js
• Proven experience designing, maintaining, and publishing frontend SDKs/libraries used by other developers (semantic versioning, changelogs, API stability)
• Hands-on experience with serverless/edge environments such as Cloudflare Workers, Vercel, or AWS Lambda
• Solid understanding of API design, HTTP fundamentals, and performance optimization
• Familiarity with build and packaging tools (Vite, Rollup, esbuild) and module systems (ESM/CJS)
• Testing experience with Jest/Vitest, Playwright, or Cypress
• Excellent written and verbal communication — capable of producing clear documentation and async updates
• Comfortable working in a remote, autonomous, and async-first team

Desirable

• We’re looking for a Senior Full-Stack JavaScript Engineer (Frontend SDK Focus) to join our Web team, reporting to Luka (Web Team Lead)
• You’ll take ownership of end-to-end delivery for our Reown Dashboard (our customer-facing control panel) and Reown AppKit (the SDK powering developer integrations)
• The role has a frontend-heavy focus (≈60% React/Next.js) while contributing to backend development (≈40%) using TypeScript and serverless runtimes like Cloudflare Workers
• You’ll be joining a high-performing, senior engineering team where autonomy, craftsmanship, and collaboration are key
• You’ll work on a production-level dashboard and SDK that powers integrations across the entire Web3 ecosystem — from small builders to major dapps
• You’ll have ownership over feature delivery from ideation to deployment
• Every engineer at WalletConnect writes technical design docs, contributes to architecture, and helps define best practices — it’s a place where your technical voice genuinely matters
• You'll own delivery for new features across Reown Dashboard and Reown AppKit, contributing both to UI and SDK logic
• Partner with Product and Design to conceptualize, scope, and build new experiences for developers integrating WalletConnect
• Build and maintain frontend SDKs and component libraries in TypeScript (framework-agnostic where appropriate) with clear APIs, strong documentation, and great DX
• Extend and optimize Cloudflare Worker–based APIs, as well as other serverless endpoints powering our products
• Translate Figma designs into accessible, performant, and reusable React/Next.js components
• Ensure reliability and quality through type-safe code, automated testing (unit/e2e), and CI/CD pipelines
• Monitor, debug, and optimize production systems using Grafana, Sentry, and related tools
• Drive performance optimizations — tree-shaking, code-splitting, bundle-size reduction, and build-time improvements
• Collaborate cross-functionally, writing technical design docs and reviewing peers’ work to maintain high engineering standards
