Profile match
Canonical is the company behind Ubuntu, the Linux distribution it has published since 2004 and which has become the most widely used operating system on public cloud instances. It earns revenue from support subscriptions, security maintenance of open source packages, and a set of infrastructure products including MicroK8s and Charmed Kubernetes for containers, MAAS for bare metal provisioning, OpenStack distributions and the Snap packaging system. The company was founded by the South African entrepreneur Mark Shuttleworth, who still owns it privately, is headquartered in London, and operates as a fully distributed organisation with staff in dozens of countries.

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.

  • Collaborate with external security consultants to test and validate kernel and crypto module components
  • Work with external partners to develop security hardening benchmarks and  audit + remediation automation for Ubuntu
  • Contribute to Ubuntu mainline and upstream projects to land solutions and benefit the community
  • Communication and collaboration within and outside Canonical to identify opportunities to improve our security posture, rapidly resolve issues, and deliver high-quality solutions on schedule

What we are looking for in you

  • Hands-on experience with low-level Linux cryptography APIs and debugging
  • Excellent software engineering fundamentals, including prior experience with C development, and the ability to demonstrate such
  • Hands-on experience with Linux system administration and shell scripting
  • Demonstrated knowledge of security and cryptography fundamentals + direct experience writing secure code and implementing best practices
  • Significant development experience working with open source libraries
  • Excellent verbal and written communications to enable efficient collaboration with internal and external partners in a remote-first environment

Additional skills that you might also bring

  • Prior experience working on FIPS/Common Criteria certified products and in-depth knowledge of the underlying standards
  • Prior experience working directly with DISA-STIG or CIS benchmarks, including related audit + remediation tooling (e.g. Compliance as Code)
  • Experience working directly with Linux Kernel
  • Prior experience with Python, OVAL (Open Vulnerability Assessment Language), and Ansible
  • History of contributions to open source projects
