What is Polygon Labs?

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.

About the Polygon Miden Team

Polygon Miden is a zkRollup focused on facilitating high-throughput and private applications. Our platform allows users to create zero-knowledge proofs of their own state changes, which are only verified by Miden. Our public testnet is scheduled to launch in Q4 2023. Currently, our focus is on constructing the rollup, recursive verification, and refining the developer experience.

Job Description

We are seeking a Senior Protocol Engineer to join our team. In this role, you will be responsible for the design and implementation of core components of the Miden rollup. You will contribute to the R&D efforts surrounding rollup architecture, which includes the state model, transaction model, execution model, etc. Your tasks will also involve the development of the Miden Node and the Miden Client. We provide you with the opportunity to work on cutting-edge technology, utilize advanced tools and modern programming languages, and gain in-depth knowledge about zero-knowledge proving systems.
