Senior Protocol Engineer

Base is planning to bring a million developers and a billion users onchain. We need your help to make that happen.

We believe that the onchain platform is the most important builder platform since the internet (“online”). We believe that the onchain platform should be open source, free to use, and globally available. And we believe that in order to make it really work, we need all hands on deck, working together to scale in a secure, decentralized, easy-to-use way.

At Base, we live by ourStay Basedvalues : we do the right thing, work hard, stay optimistic, prioritize the team, and push creative boundaries—all while building the future of onchain. We value aZone 3+ work ethic, where our team rises to the challenge, embraces hard weeks, and makes small to significant personal tradeoffs when necessary to drive impact and innovation.

Base is incubated within Coinbase and plans to progressively decentralize in the years ahead. We believe that decentralization is critical to creating an open, global crypto economy that is accessible to everyone.

Base is built on Optimism’s open-source OP Stack. We’re joining as the second Core Dev team working on the OP Stack to ensure it’s a public good available to everyone; and contributing a portion of sequencer revenue to funding public goods.

We are looking for a strong protocol engineer to join the Base team to help us continue scaling in order to pave the way for billions of people coming onchain.

What you'll do :

Hack on execution client internals (geth, reth, etc.) to extend capacity and capabilities of these systems well beyond current standards.

Develop representative loads against which to rigorously benchmark performance.

Improve OP stack through efforts such as reducing the footprint of data that needs to be made L1-available.

Helping with important external scaling efforts such as PeerDAS and Danksharding.

What we look for in you :

Some understanding of geth and / or reth internals (deep understanding of either a huge plus).

Familiarity with database internals and high performance database systems.

Understanding of the Ethereum scaling roadmap, and crypto-forward knowledge more generally.

A track record of successful scaling of an existing high throughput system.

Nice to haves :

Experience in software parallelization, including but not limited to optimistic concurrency and operation pipelining.

Understanding of optimized approaches to Ethereum state management such as Erigon / Reth’s flat DB, FirewoodDB, MonadDB, etc.

Deep understanding of EVM internals, and (just-in-time) compilation expertise that might be applied to it.

Onchain-forward experience, including familiarity with onchain activity such as interacting with Ethereum addresses, using ENS, and engaging with apps or blockchain-based services.
