Key Responsibilities
  • Develop and enhance Linux cryptographic libraries (OpenSSL, Libgcrypt, GnuTLS) for FIPS and Common Criteria certification.
  • Design and implement automation tools to audit and remediate systems for DISA-STIG and CIS benchmark compliance.
  • Collaborate with Canonical's kernel team, external consultants, and open source communities to deliver security solutions.
  • Engage with organizations such as DISA and CIS to draft and implement security hardening benchmarks for Ubuntu.
  • Identify and address gaps in security frameworks, influencing team and security culture.
Required Skills & Qualifications
  • Proven experience with low-level Linux cryptography APIs and debugging.
  • Strong proficiency in C programming and Linux system administration.
  • Direct experience with FIPS/Common Criteria standards and secure coding best practices.
  • Hands-on knowledge of DISA-STIG, CIS benchmarks, and compliance automation tools (e.g., Compliance as Code).
