Head of Security

OpenSea is the gateway to web3’s next chapter—where NFTs, fungible tokens, and emerging digital assets converge to create open, user-owned economies. As a foundational player in the crypto space, we’re building infrastructure that supports millions of users and sets new standards for how people discover and exchange digital value.

Our team is small but mighty: hands-on, fast-moving, and deeply committed to shipping meaningful work. We're remote-first by design, AI-empowered by default, and guided by values that prioritize ownership, trust, and progress. At OpenSea, you’ll be challenged to grow fast while being supported by a talent-dense team shaping the future of crypto.

We’re looking for a Head of Security to join OpenSea to champion security for our team, platform, and millions of users. Security is key to everything we do, but today is distributed among our engineers, as well as a few security specialists. This role will level up our investment & expertise in the domain.

You will own security end-to-end: application, operational, and corporate with a focus on hands-on execution mixed with high-level strategy setting, shaping the security posture for one of the most prominent platforms in web3.
