Your Role

As a Senior Engineer on the PoS Engineering team at Polygon Labs, you’ll focus on strengthening the peer-to-peer networking capabilities across all three of our core clients—Bor, Erigon, and Heimdall. This role is ideal for someone passionate about distributed systems and low-level networking, who wants to solve complex stability and connectivity challenges at scale.

Working closely with a high-caliber team of engineers across time zones, you will play a key role in ensuring the network reliability and performance of the Polygon PoS chain. You’ll take ownership of diagnosing and resolving hard-to-find issues in our peer-to-peer layer and will help us evolve our network topology to meet the next phase of growth.

Your Responsibilities

• Design, implement, and optimize peer-to-peer networking components in the Bor, Erigon, and Heimdall clients.

• Analyze and improve network stability by identifying peering bottlenecks, protocol edge cases, or propagation inefficiencies.

• Investigate incidents and contribute to root cause analysis (RCA) efforts related to network partitions, peer discovery failures, or gossip performance issues.

• Collaborate closely with internal protocol and infra teams to align client behavior with network goals.

• Contribute to client documentation and architecture discussions around networking layers and system resilience.

• Stay up to date with trends and developments in distributed systems and peer-to-peer infrastructure.

What You’ll Need

• 5+ years of experience in systems or infrastructure engineering, ideally working on distributed systems or blockchain clients.

• Deep expertise in Go (Golang), with strong knowledge of networking libraries, protocols (TCP/UDP), and debugging tools.

• Demonstrated ability to solve complex problems in live production systems with a proactive, ownership-first mindset.

• Experience working on peer-to-peer networking protocols or low-level infrastructure systems.

• Comfortable working in a remote, asynchronous environment across time zones (EMEA, East Coast US, or South America preferred).

Preferred Qualifications

• Prior experience working on blockchain or decentralized network infrastructure.

• Familiarity with the Ethereum ecosystem and Polygon PoS architecture.

• Exposure to multiple client implementations and consensus protocols.

• Strong written communication skills, especially around documenting technical findings or incident reviews.
