• Serve as the single point of contact for both our government Customer and our industrial partners regarding all security-related engineering, compliance, and operational matters

What you'll need

• Successfully delivered complex systems engineering or security engineering solutions within aerospace, defence, or telecommunications projects
• Deep expertise operating within highly classified environments and implementing strict military and government security frameworks
• Hands-on experience integrating hardware and software security units, cryptographic modules, and secure communications protocols into complex technical systems
• Ability to clearly and concisely translate complex security requirements to non-security engineers, customers, and executive stakeholders
• Advanced degree in Cybersecurity, Electrical Engineering, Computer Science, Aerospace Engineering, Systems Engineering, or a related STEM discipline
• Ability to collaborate effectively with multidisciplinary teams, including payload engineers, ground software developers, and mission operators
