Requirements - At least five years of professional experience, with meaningful software engineering experience building production systems before transitioning into security. - Product or application security experience across threat modeling, secure design, white-box code review, and vulnerability testing. - Proficiency in a systems or backend language such as Rust, Go, C++, or Python, and willingness to read production code and build tools. - Experience creating security automation and conducting security reviews of production software. - Understanding of identity and access management, software supply-chain risk, and AI security testing. - Clear written communication and the ability to work autonomously with high ownership.

Nice to have - Experience in web3, cryptocurrency, or DeFi. - Familiarity with enterprise identity and SSO, privileged access management, Linux hardening, multisignature key management, hardware security modules, or trusted execution environments.
