About The Position

Ready to do the most impactful work of your career? At Coinbase, we are uncompromising on our mission to increase economic freedom. The bar is high, the environment is intense, and we like it that way. This isn't a place for complacency, it’s a place to be pushed past your perceived limits. If you're ready to build the future of finance alongside people who refuse to settle for "good enough," you belong here. Coinbase is a remote-first, but not remote-only company. Expect to get together quarterly for intense in-person working sessions called “surges.” Security is a primary competency at Coinbase, and the Threat Intelligence team within Security Operations keeps a watchful eye over every aspect of it. As a Senior Onchain Investigator, you'll own end-to-end onchain investigations into the threat actors targeting Coinbase and the crypto ecosystem. You'll cluster illicit wallets, fuse OSINT with onchain evidence, and turn findings into detections, blocks, and decisions that protect customers and products. This role leads investigation methodology for the team, not just individual cases.
