• Solid grasp of async programming (Promises, async/await, event loop, queues)
• Strong knowledge of API design (REST, GraphQL, WebSockets) and integration
• Skilled in data structures and modeling for web-scale applications
• Deep understanding of performance optimization (caching, load balancing, profiling)
• Experience with concurrency in JS (worker threads, clustering, async queues)
• Ability to debug across layers (frontend, backend, database, network)

• World-class codebases – Condense years of learning into months by working on some of the most advanced and technical JavaScript projects in the world.
• Become AI-native – Get early access to cutting-edge AI dev tools, from GPT-4 to autonomous agents that create tickets based on your PR comments.
• Fully remote + async – Work when, where, and how you want. No micromanagement.
• Gain OSS experience – Build your open-source profile and contribute to important JavaScript and Node.js repositories.
• Build lasting connections – Collaborate with people from 15+ countries through game nights, hackathons, and local meetups.
