About the role

  • Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth.
  • This isn't just a standard security role; you will be a primary architect and implementer of the cryptographic foundations that protect our satellite constellation and the sensitive data moving between Earth and orbit.

Responsibilities

  • Design and implement production-ready cryptographic modules for key management, identity and access management (IAM), and secure communication protocols (e.g., TLS, AES-GCM, ECC).
  • Develop secure data-at-rest solutions for persistent memory (PMEM) architectures, ensuring that sensitive cryptographic material stored in non-volatile RAM is encrypted and protected against cold-boot or physical extraction attacks.

Requirements

  • Proficiency in Python for security tooling.
  • Systems Programming: Direct experience programming for persistent memory or non-volatile storage, including an understanding of memory-mapped files and data consistency models.
  • Security Infrastructure: Hands-on experience with Cloud Security (AWS), Kubernetes security, and automated CI/CD security scanning (SAST/DAST).
  • 5+ years of software engineering experience with a heavy focus on security-sensitive applications.
  • Hands-on experience with Cloud Security (AWS), Kubernetes security, and automated CI/CD security scanning (SAST/DAST).

Nice to have

  • Experience with Satellite Ground Segment software or aerospace communications.
  • Knowledge of Post-Quantum Cryptography (PQC) standards.
  • Familiarity with hardware-level security and side-channel attack mitigation.
  • For U.K. Roles: To comply with U.K. regulations, this role requires Baseline Personnel Security Standard (BPSS) checks, and successful candidates must be eligible to obtain UK Security Clearance (SC).
  • For Canada Roles: Successful candidates must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR.
  • We celebrate diversity and are committed to creating an inclusive environment for all employees.
