Job description

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 with 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 develop automation tooling to audit deployed systems for DISA-STIG and CIS benchmark compliance. You will collaborate with internal and external stakeholders to identify gaps and develop new solutions. This role offers the chance to influence team and security culture, facilitate technical delivery, and drive team direction. You will work closely with Canonical's kernel team and the wider engineering organization to influence features impacting all Ubuntu users.

Day-to-day responsibilities

1. Collaborate with other engineers to achieve and retain various security certifications.
2. Extend and enhance Linux cryptographic components (OpenSSL, Libgcrypt, GnuTLS, etc.) for FIPS and CC certification.
3. Work with external security consultants to test and validate kernel and crypto modules.
4. Develop security hardening benchmarks and automation for Ubuntu in partnership with external organizations.
5. Contribute to Ubuntu mainline and upstream projects.
6. Communicate and collaborate to improve security posture, resolve issues, and deliver solutions.

What we are looking for in you

• Hands-on experience with low-level Linux cryptography APIs and debugging.
• Strong software engineering fundamentals, including experience with C development.
• Experience with Linux system administration and shell scripting.
• Knowledge of security and cryptography fundamentals, with experience writing secure code.
• Development experience with open source libraries.
• Excellent communication skills for remote collaboration.

Additional Skills That You Might Also Bring

• Experience with FIPS/Common Criteria products and standards.
• Experience with DISA-STIG or CIS benchmarks, including audit and remediation tooling.
• Experience working with the Linux Kernel.
• Knowledge of Python, OVAL, and Ansible.
• Contributions to open source projects.
