About the company
Polygon Labs develops Ethereum scaling solutions for Polygon protocols. Polygon Labs engages with other ecosystem developers to help make available scalable, affordable, secure and sustainable blockchain infrastructure for Web3. Polygon Labs has initially developed a growing suite of protocols for developers to gain easy access to major scaling solutions, including layer 2s (zero-knowledge rollups and optimistic rollups), sidechains, hybrid chains, app-specific chains, enterprise chains, and data availability protocols. Scaling solutions that Polygon Labs initially developed have seen widespread adoption with tens of thousands of decentralized apps, unique addresses exceeding 225 million, over 1.2 million smart contracts created and 2.56 billion total transactions processed since inception. The existing Polygon network is home for some of the biggest Web3 projects, such as Aave, Uniswap, and OpenSea, and well-known enterprises, including Robinhood, Stripe and Adobe. Polygon Labs is carbon neutral with the goal of leading Web3 in becoming carbon negative.
Job Summary
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. 📍Relentless commitment to quality – You champion a testing-first mindset and implement unit, integration, and end-to-end tests.
What You'll Need
📍6–8+ years of hands-on full-stack engineering experience, with deep roots in both frontend and backend. 📍At least 4 years steeped in web3—building with blockchain protocols, smart contracts, and decentralized tooling. 📍Mastery of modern JS/TS frameworks like React, Next.js, or Vue.js—your frontend skills should be second nature. 📍Deep knowledge of databases, both SQL (Postgres) and NoSQL (Mongo, Firestore), and when to use which. 📍Backend prowess with Node.js, REST APIs, and microservice architectures; experience with containers (Docker, Kubernetes) is a must. 📍A solid grasp of Intent-Based Bridging and Solver Networks—bonus points if you’ve worked on them in production. 📍Ability to read, understand, and integrate Solidity contracts into real-world applications.
If this role isn’t the perfect fit, there are plenty of exciting opportunities in blockchain technology, cryptocurrency startups, and remote crypto jobs to explore. Check them on our Jobs Board.
