Job Summary:

The Network Engineer will support the Air Force Research Laboratory (AFRL) Space Vehicles Directorate in designing, implementing, maintaining, and securing network infrastructure for space technology experiments and mission operations. This role is critical to enabling hardware/software-in-the-loop testing environments, ground system operations, and multi-classification level network architectures supporting space experimentation and flight operations. The Network Engineer will work with classified networks, cross-domain solutions, and cloud computing architectures while ensuring compliance with DoD cybersecurity requirements and Authorization to Operate (ATO) standards. The ideal candidate will have a strong technical background in network engineering with specific experience supporting:

• Authorization to Operate (ATO) processes: Support obtaining and maintaining compliance with ATOs for ground and space systems in accordance with DoD Risk Management Framework (RMF), including preparation and submission of ATO packages for information networks and network experiments
• Cloud-based ground station network security: Implement and maintain security controls for cloud computing architectures, disaggregated ground networks, hardware/software-in-the-loop testing environments, and mission operations infrastructure supporting space technology experimentation
• Classified network administration and cross-domain solutions: Design, implement, and maintain classified networks (SIPR, JWICS, and other specialized systems) and deploy cross-domain solutions (CDS) to securely move data between different classification levels, external connections, and point-to-point transmissions
• Mission operations center cybersecurity: Support network infrastructure for Mission Operations Centers, spacecraft operations, flight operations, and spacecraft command and control systems across multiple classification levels
