Senior Protocol Engineer

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 7000+ applications hosted, 1B+ total transactions processed, ~100M+ unique user addresses, and $5B+ in assets secured.

The Role

We’re looking for an experienced engineer to help us design the Polygon Zero protocol and implement our reference client. This involves peer discovery, push and pull based gossip, consensus, storage, and so forth. If any of this sounds interesting, please reach out!

While our protocol is similar to Ethereum’s in many respects, one difference is that it uses proof-of-stake, with BFT consensus for fast finality. Another is that we have redesigned the VM in a way that is tailored to zero-knowledge proofs. Finally, of course, our protocol contains a proof “overlay” to demonstrate that all transactions are valid.

What you need to succeed:

• Engineering, ideally with experience in Rust
• Blockchain protocols
• Databases, particularly embedded ones
• Consensus algorithms

Benefits

• Work from anywhere (Remote first)
• Flexible working hours
• Flexible vacation policy
• Competitive Salary

Polygon is committed to a diverse and inclusive workplace and is an equal opportunity employer. We do not discriminate on the basis of race, national origin, gender, gender identity, sexual orientation, protected veteran status, disability, age, or other legally protected status.
