The Team

Kraken’s world-class security team is growing. As we continue to grow and mature our on-chain presence, we need someone with a strong Web3 security background to help build our program and tooling for enterprise scale. 

This role will be reporting through Kraken’s Application Security function. You will have the benefit of partnering with domain experts in our existing stack and enterprise software tooling while still having the opportunity to come up with creative solutions in the emergent field of Web3 Security. 

We are leaders in the Security space. You will be partnering with peers who have submitted critical bug reports to some of the biggest names in both Web2 and Web3 as part of our regular campaigns and research. Kraken is a founding member of several new Web3 standards organizations and you will also have the chance to make a lasting impact on the industry as a whole. 

The ideal candidate will be comfortable working across a variety of teams, including Application Security, Red Team, and Cloud Security to help make informed decisions. 

This is a fully remote role.
