Linux Cryptography and Security Engineer

This is a unique opportunity to use your software engineering and cryptography skills to build and maintain the security foundation that enables Ubuntu and its users to operate securely and remain compliant to international information security standards such as FIPS 140-3 and Common Criteria. You will use your applied cryptography, Linux Security, and coding skills to enhance the Ubuntu distribution and work with organizations such as DISA and CIS to draft and implement security hardening benchmarks for Ubuntu.

As a member of the Security Hardening team you will work with and develop automation tooling to audit deployed systems for DISA-STIG and CIS benchmark compliance. You will interact with internal and external stakeholders to identify gaps in our frameworks, and develop new solutions to address these challenges. In this role you will have the opportunity to influence team and security culture, facilitate technical delivery, and help drive team direction and execution. You’ll collaborate closely with Canonical’s kernel team as well as the wider engineering organization to drive features impacting all Ubuntu users.
