Senior Golang Engineer

Polygon is a popular Layer-2 solution on the Ethereum blockchain. It functions as a side-chain, letting Dapps on Ethereum operate with low fees and almost instant settlements.

Polygon is highly scalable and already supports upcoming Ethereum features such as Scaling and Interoperability. As one of the most popular Layer-2 solutions for Ethereum, there are many Polygon Jobs that are always available.

Using Polygon, one can create Optimistic Rollup chains, ZK Rollup chains, stand-alone chains or any other infrastructure required by the developer. Polygon effectively transforms Ethereum into a full-fledged multi-chain system (Internet of Blockchains). This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc., with the advantages of Ethereum’s security, vibrant ecosystem and openness. With Polygon, new features are being built around the proven technology to expand the ability to cater to diverse needs from the developer ecosystem.

Job Description

What is Polygon?Polygon is the leading platform for Ethereum scaling and infrastructure development. Its growing suite of products offers developers easy access to all major scaling and infrastructure solutions: L2 solutions (ZK Rollups and Optimistic Rollups), sidechains, hybrid solutions, stand-alone and enterprise chains, data availability solutions, and more. Polygon’s scaling solutions have seen widespread adoption with 37,000+ applications hosted, 1B+ total transactions processed, 140M+ unique user addresses, and $5B+ in assets secured.

What does the zkEVM Team do?Polygon zkEVM is the first zero-knowledge (ZK) scaling solution that’s fully compatible with Ethereum: all existing smart contracts, developer tools, and wallets work seamlessly. The zkEVM harnesses the power of ZK proofs to reduce transaction cost and massively increase throughput, all while inheriting the security of Ethereum L1.

Job Description We're looking for a Senior Golang Developer to join the Backend team of zkEVM and help develop the node that will be operating the EVM zkRollup. Your task scope will include implementing Merkletrees, Ethereum interfaces (read/write smart contracts), EVM logic, as well as more “traditional” backend features such as APIs, DBs, etc. In addition, you will collaborate with team members in making architectural decisions, choosing best practices, and bringing in new ideas. This is an exciting opportunity to take an active part in the blockchain space and contribute to the decentralization of the future. Find the zkEVM documentation at: docs.hermez.io
