Senior Blockchain Security Engineer

Ready to be pushed beyond what you think you’re capable of?

At Coinbase, our mission is to increase economic freedom in the world. It’s a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform — and with it, the future global financial system.

To achieve our mission, we’re seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system. We want someone who is eager to leave their mark on the world, who relishes the pressure and privilege of working with high caliber colleagues, and who actively seeks feedback to keep leveling up. We want someone who will run towards, not away from, solving the company’s hardest problems.

Our work culture is intense and isn’t for everyone. But if you want to build the future alongside others who excel in their disciplines and expect the same from you, there’s no better place to be.

While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported.

Security is a primary competency at Coinbase, and the Security Team keeps a watchful eye over every aspect of it. Every day, we go to battle against some of the most sophisticated attackers in the world to protect billions of dollars worth of digital assets and ensure that our customers and employees can enjoy a safe, trusted experience. As Coinbase scales globally, our team is scaling along with it, using a blend of tooling, automation, and strategic team growth to ensure that we’re well-equipped to protect the next billion users of crypto.

Blockchain Security (BlockSec) team’s mission is to secure funds and data from protocols to wallets. Coinbase has a unique opportunity: enabling our customers to easily and securely interface with blockchains, a.k.a. digital asset networks, a.k.a. cryptocurrencies. Blockchains are a cutting edge technology, with many unique security considerations for any entity that supports interaction with them. Understanding those unique considerations requires deep expertise in blockchains and the ability to maintain that expertise over time.
