Intro

This is a unique opportunity to contribute to an essential part of Ethereum infrastructure, which enables >75% of transactions in Ethereum's ecosystem to settle onchain.
The PBS Foundation, a non-profit organization originally initiated by Flashbots, sits at the core of the orderflow ecosystem to maintain software and market mechanisms around Proposer-Builder Separation (PBS) and mev-boost.

You'll be step by step onboarded into a high responsibility role for mev-boost and support the whole ecosystem around it. This means you'll get in-depth insights into the orderflow market structure and infra of MEV (Maximal Extractable Value) on Ethereum.

Over time you'll own and upgrade essential PBS infrastructure and be deeply involved in shipping future Ethereum upgrades (hardforks).

Current and future responsibilities will be:

• Develop ownership of mev-boost and surrounding infrastructure
• Ensure security and resilience of PBS orderflow pipeline
• Consistently improve dev workflows incl. CI automation and advancing unit and e2e tests
• Navigate upgrades around Ethereum hardforks starting from early devnets
• Collaborate closely with Execution Layer and Consensus Layer client teams
• Follow the Ethereum MEV/PBS ecosystem research and development

Codebases you'll be involved with:

• mev-boost, mev-boost-relay, go-boost-utils
• rbuilder, builders-specs, relay-specs
• go-eth2-client, go-builder-client

Must have:

• Strong proficiency with Go (Golang) and performance-optimized code
• Networking experience: TCP/IP, RPC, libp2p
• Extensive database knowledge: Redis, SQL and NoSQL
• Security-first mindset and interest in adversarial-resistant systems
• In-depth testing, CI and DevOps experience
• Passion for distributed systems and open source ethos

Great to have:

• Good working knowledge of Rust (or other systems programming languages)
• Understanding of the Ethereum infrastructure and the PBS architecture + ecosystem
• Experience with designing distributed systems and blockchains (ideally Ethereum execution and consensus clients)
• Interest in cryptography and state-of-the-art computer science research
• Exposure to working in startups or other high iteration speed environments

Innovative Environment: Work on cutting-edge Ethereum stack with leading experts in MEV research and infrastructure development.

Competitive Compensation: Receive a competitive salary and opportunities for deep engagement in Ethereum’s research ecosystem.

Flexible Work Conditions: Be part of a fully remote team with flexible working conditions, high autonomy and a strong open-source ethos.

High-Impact Work: Contribute to projects that directly influence Ethereum's decentralization, censorship resistance, and fairness in MEV value distribution.

We're excited to hear from you and can't wait to have you join our closely-knit team and become an essential part of the core Ethereum ecosystem.
