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 our Stay Based values: 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 a Zone 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 Senior Fullstack Engineer (Backend leaning) to join the Base team with emphasis in backend onchain engineering, to enable and accelerate the success of Base.

What you'll be doing:

Building and maintaining backend Golang systems that power Base
Working with Kubernetes and Cloud services to automate and maintain critical blockchain infrastructure
Engaging in research and prototyping of groundbreaking ideas to improve efficiency and scalability of blockchain clients

What we look for in you:

You have at least 5 years of experience in software engineering or systems engineering
You've developed and shipped features of core backend systems at massive scale
You’re familiar with current trends and best practices in infrastructure and systems design
You write high quality, well tested and maintainable code

Nice to haves:

You’re comfortable with Golang, Geth, Foundry, Solidity, or other crypto tools
You have contributed to open source crypto projects, for example OP Stack contributions or Base contributions
You’ve familiar with Kubernetes or cloud providers such as AWS or GCP

OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
