We are seeking an experienced and highly motivated Security System Architect to secure next-generation satellite systems and support ground infrastructure. Reporting to the Senior Director, System Architecture and Release Train, you will lead the integration of cybersecurity across the product lifecycle, ensuring security is embedded from concept and design through deployment and operations.
As a member of the System Architecture team, as the Security Champion you will work closely with Segment Domain Architects, engineering teams, and Product Cybersecurity stakeholders to ensure cybersecurity requirements are effectively incorporated into system architectures and product designs. Acting as the bridge between system architecture and cybersecurity, you will champion secure-by-design principles, assess cyber risks, and guide architectural decisions that enhance the resilience and security of space, ground, network, and cloud-based systems.
For satellite, ground segment, network, and cloud-based systems, define and maintain:
common cybersecurity development architecture,
assist in translating security requirements into actionable items for the development teams,
ensure that the development teams have a consistent understanding of the required security paradigms, and can consider them at the needed development stages,
develop guidelines on best adoption practices and design principles in response to guidance from Product Cybersecurity and Governance, Risk and Compliance teams.
Implement security verification strategies and review results from penetration testing, code analysis, fuzzing, and other security assessments.
10+ years of experience in cybersecurity, system architecture with proven product development experience, product security, or embedded systems security.
Experience in aerospace, satellite communications, telecommunications, defense, or other mission-critical environments.
Experience with security assessment tools and practices, including SAST, DAST, SCA, vulnerability management, and SIEM platforms.
Experience with Kubernetes, VMs, container security, service mesh architectures, PKI, Security devices, and certificate lifecycle management.
This role plays a critical part in ensuring the security, resilience, and mission assurance of our next-generation satellite and ground systems while enabling secure innovation across the Development organization.
This role serves as the cybersecurity architectural authority for satellite payload and ground system development, ensuring that security is treated as a foundational design requirement and strategic differentiator. Acts as a bridge between the Product cybersecurity team and the development teams. The Security System Architect will play a critical role in protecting mission integrity, safeguarding customer trust, and enabling secure growth of the organization's space and communications capabilities.
