Job Description

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

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.

The Protocol Security team ensures the security of all onchain development at Coinbase. We partner closely with product teams to make sure that our users can safely and confidently engage with the onchain world.

What you’ll be doing (ie. job duties):

  • Develop onchain security strategies and perform security assessments and threat modeling of various blockchain protocols.
  • Lead from the front, be proactive and thorough, and identify top onchain security risks and develop strategies to deal with them.
  • Provide expert technical guidance to the team in building new frameworks, analysis tools, and security products.
  • Lead the way in establishing best practices and engage with product and eng teams to get them adopted.
  • Coach and mentor Protocol Security team members to build new skills and be crypto-forward.
  • Guide Protocol Security to the cutting-edge of security technologies for blockchain protocols and help set standards for the rest of the industry to follow.

What we look for in you (ie. job requirements):

  • You have extensive knowledge of onchain ecosystems, including the inner workings of L1 and L2 networks, DeFi protocols, staking, etc.
  • You excel in identifying machine-level, transaction-level, and business logic-level vulnerabilities in smart contracts and protocol infrastructure.
  • You have 3+ years of smart contract auditing experience and have led the audit of several complex protocols.
  • You have an energy and self-drive for continuous learning as crypto is a constantly and rapidly changing space.
  • You are passionate about mentoring and growing blockchain security engineers, as well as willing to learn from your team.
  • You excel in clear, direct, and kind communication with technical and non-technical stakeholders.
  • You have experience building relationships with security, product, and engineering teams.
  • You balance long term strategic thinking with short term tactical planning.

Safe Remote Job Search Tips

Verify Employer Thoroughly

Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.

Never Pay to Get a Job

Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.

Safeguard Your Personal Information

Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.

Scrutinize Communication & Interviews

Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.

Beware of Unrealistic Offers

If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.

Insist on a Formal Contract

Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
