Staff Full Stack Engineer

As a Full Stack Staff Engineer on the Applications and SDK Development team at Polygon Labs, you'll step into a mission-critical role where code meets creativity. You won't just be writing software—you'll be engineering the connective tissue of web3 experiences. From building intuitive bridge and staking interfaces to architecting powerful multi-chain SDKs, your work will power seamless interactions across the Polygon network. Think of this as your chance to shape the future of blockchain usability. You'll thrive here if you're energized by technical challenges, obsessed with UX in the decentralized world, and eager to mentor a team of sharp minds. If you get a rush from delivering secure, scalable systems that millions rely on—this is the adventure for you. Your Responsibilities: - Architect and build full-stack applications that talk to smart contracts and EVM chains—delivering snappy, intuitive web3 experiences. - Take the reins on system design for dApps, multi-chain SDKs, and smart contract indexers spanning multiple Layer 2 networks. - Champion best practices in code quality, scalability, and performance while tackling tech debt like a boss. - Mentor a dynamic team of engineers and collaborate across disciplines—from Product to Security—to deliver resilient, future-ready solutions. - Contribute to planning, sizing, and de-risking of complex projects with many moving parts. - Keep a pulse on performance, security, and observability to ensure smooth sailing in production.
