As the SME Network Engineer, you will shape the tactical and enterprise networking foundation of Major Release 2 (FY 25-27), orchestrating SATCOM, Software Defined Radios (SDR), cross-domain solutions, and software-defined networking to connect airborne platforms to the Digital Infrastructure (DI) and the broader DAF BATTLE NETWORK. Essential Job Functions Architect & Design Lead creation of the PG network reference architecture including Nomad hardware, Smith software builds, and Watch node-management elements. Define routing schemas (BGP, OSPF, IS-IS), QoS policies, IPSec/crypto overlays, and multi-level security/cross-domain data-flow rules complying with NSA and DISA STIGs. Produce SysML/CAMEO artifacts for government-owned digital thread. Integration & Lab Leadership Specify/configure routers, switches, firewalls, SATCOM modems, and SDRs in the Integration SIL. Develop interface control documentation (ICDs) for airborne PIMs. Create automated test harnesses (IXIA/TestCenter, Spirent, Ansible) to validate throughput, latency, packet-loss, and IA posture before DT/OT. DevSecOps & Cyber Hygiene Embed network security controls in the PG DevSecOps pipeline; champion zero-trust principles and continuous ATO artifacts (RMF eMASS packages, ACAS/SCAP scans). Guide SDN implementation (SD-WAN, OpenFlow, etc.) for dynamic airborne/ground path selection. Fielding & Operations Collaborate with platform SPOs and flight-test teams to translate lab configurations into flight-worthy builds. Draft Interim Authorizations to Test (IATT) and airworthiness network annexes. Support Watch help-desk playbooks, operational runbooks, and remote monitoring dashboards (Elastic, Grafana, Prometheus). Leadership & Mentoring Serve as chief technical adviser to Government IPT leads; brief network readiness, risk, and performance at program reviews. Mentor mid-level engineers and ensure knowledge transfer to Government personnel. Required Skills & Qualifications U.S. Citizenship required due to customer sensitivity. Bachelor's degree in Electrical Engineering, Computer Engineering, or related field (Master's preferred). Minimum 8 years' experience designing, integrating, and securing DoD or IC mission-critical IP networks. Active TS/SCI clearance. Deep expertise in routing/switching (Layer 2/3), SATCOM backhaul, RF/mesh networking, and transport enclaves in contested/bandwidth-limited environments. Proven experience with cross-domain solutions, NSA Type-1 crypto, and multi-level security architectures. Hands-on experience with network test/validation tools and scripting/automation (Python, Ansible, Terraform). Desired Skills CCNP, CCIE, JNCIE, or equivalent expert-level certification. Prior work on CJADC2, ABMS, OMS/UCI, tactical data links (Link-16/22, TTNT), or airborne networking programs. Familiarity with containerized networking (CNI plugins, Service Mesh) and classified DevSecOps pipelines (Platform One, Iron Bank). Experience shepherding RMF packages through eMASS to full ATO. Agile/Scrum or SAFe certification.
