Summary

Polygon Labs’ PoS Team’s vision is to provide a simple, fully EVM compatible, scaling solution for Ethereum that is connected to the AggLayer. The team is responsible for developing, running and maintaining the protocol and software clients that power Polygon PoS chains including Mainnet and Testnets.

Polygon Labs is looking for a Senior Software Engineer with solid GoLang knowledge who can work on different layers of PoS including Bor and Heimdall and their underlying client implementations - Geth, Erigon, Cosmos-SDK, CometBFT. Ideal candidates will have experience working in a distributed team, collaborating with multiple teams (external and internal), doing code reviews, mentoring junior developers and implementing best practices.

Key Job Responsibilities 

* Client and protocol development

* Keeping track of improvements and changes happening upstream (Ethereum)

* Contribute to auxiliary tools that help in testing - deploying testnets, end to end testing, load testing, etc

* Work closely with internal and external teams for development, testing and roll out of new features

* Mentor colleagues

A Day in the Life

“A Day in the Life might include…”

* Writing code to implement a new feature or fix a bug

* Going through upstream codebase for interesting changes, cherry picking and testing them on PoS

* Brainstorming on new ideas and adding them to Polygon Improvement Proposals (PIPs) for further discussion and implementation

* Reviewing code, architecture and technology decisions by other team members

About the Team

* We are a pretty distributed team, with team members from timezones more than 12 hours apart. However, we also share a very deep bond, being the oldest tech team in the company that has been around since the inception of Polygon.

* It’s the same team that ensured that PoS handled +160M inscriptions (double the amount of any other major chain), and processed a record 16.5M txs in one day, without blinking.

* Humble and down to earth, always ready to help team members.

* By joining this team you will meet amazing colleagues with similar disciplines, from whom you can learn, share and drive the future of Web3.

What you’ll need - Preferred Qualifications

* Mastery in GoLang programing language

* Experience with debugging and testing tools

* Great written and verbal communication skills

* Experience mentoring or training others

* Experience in Blockchains is a plus

* High level understanding of the Ethereum Virtual Machine is a plus

* Experience with Ethereum clients like Geth, Erigon and Reth is a plus
