Senior Spacecraft Avionics Security Engineer

The Senior Spacecraft Avionics Security Engineer is the technical authority for all space vehicle and avionics product-level security of Millennium's space systems.

You will design, implement, and sustain cryptographic subsystems, red/black separation, and end-to-end security architectures that protect hardware, software, data, and communications throughout the entire vehicle lifecycle and drive security requirements, processes, and verification at the product and mission level.

Responsibilities:

• Mission and Product-Level Security Management:
• Define vehicle-wide security architecture, select and integrate space-qualified crypto devices, implement secure boot, key storage, and red/black isolation
• Develop and maintain system security requirements, verification plans, and certification artifacts (DoD RMF, customer security clauses)
• Develop threat assessment models and tailored approaches to counter them
• Support product-level security requirements definition, implementation, verification, and validation across the full lifecycle
• Work with software, hardware, and systems engineering teams to develop new processes and procedures for enhanced cybersecurity implementations at both the product and system level

• Networking Systems Engineering:
• Lead design, requirements management, and integration of space-vehicle and constellation-level networks (on-board LANs, inter-satellite mesh, space-to-ground links)
• Define and maintain CONOPS, ICDs, and requirements for routing, virtualization, VPN tunneling, VLAN segmentation, and QoS across heterogeneous RF/optical links
• Apply enterprise networking principles (WAN/LAN/WLAN, IPv6, MPLS, IPsec) to distributed space systems while preserving red/black separation
• Direct integration and verification activities that validate networking implementations

• Stakeholder & Business Development Support:
• Lead customer interactions on product and system level cybersecurity for space systems
• Develop presentation content and brief customers on Millennium product security approaches
• Assist the business-development team in crafting compliant proposals that meet customer cybersecurity and networking requirements

• Supplier & Government Coordination:
• Define security and networking requirements for component/subsystem suppliers; review supplier deliverables; liaise with government agencies, customers, and industry groups to influence standards and risk-acceptance processes

Requirements:

• Bachelor of Science degree in Engineering (with a focus in Electrical, Mechanical or Aeronautical), Computer Science, Data Science, Mathematics, Physics, Chemistry or non-US equivalent qualifications directly related to the work statement
• 5+ years experience working spacecraft/product security
• Technical understanding of SV avionics architectures
• Technical understanding of SV flight software architectures to include embedded Linux
• Technical understanding of product cybersecurity features to include root of trust, secure boot, etc.
• Familiarity with DoD Risk Management Framework (RMF)
• This position requires the ability to obtain a U.S. Security Clearance for which the U.S. Government requires U.S. Citizenship. A final U.S. Security Clearance Post-Start is required

Preferred Qualifications:

• Experience working with cryptography and Anti-Tamper design knowledge
• Experience working with TEMPEST designs
• Methodical design, testing, and troubleshooting capabilities
• Must be versatile and able to perform and manage multiple tasks concurrently
• Outstanding communication and presentation skills
• Experience with DoD RMF controls implementation
• 10+ years experience working spacecraft/product security
• TS/SCI clearance

Benefits:

• Competitive base pay and variable compensation opportunities
• Health insurance, flexible spending accounts, health savings accounts, retirement savings plans, life and disability insurance programs

Pay Range:

• Level 4: $146,200 - $215,000
