Senior Software Engineer, Tactical Networking

• Design and implement Layer 3 networking for DDIL environments - VPN tunnel management, dynamic routing, and multi-path failover across tactical radios, satellite, and wired transports
• Build radio integration layers that abstract diverse tactical waveforms behind a unified networking interface
• Design QoS scheduling and traffic shaping to ensure mission-critical data flows under severe bandwidth constraints
• Build network management and orchestration systems for real-time topology configuration and adaptation
• Architect PKI infrastructure for the Lattice mesh - certificate authorities, automated issuance/renewal, revocation (CRL/OCSP), and secure node bootstrapping
• Design certificate lifecycle management that handles rotation and re-keying across nodes with intermittent connectivity
• Implement zero-trust identity verification across all mesh communication paths
• Treat network observability as a first-class citizen - build Prometheus metrics, Grafana dashboards, eBPF-based instrumentation, and CLI tooling for topology inspection, link health, and certificate status
• Debug complex networking issues from packet captures on deployed assets to cloud infrastructure, To ensure your safety and help you navigate your job search with confidence, please keep the following critical points in mind:
• No Financial Requests: Anduril will never solicit payment or demand personal financial details (such as banking information, credit card numbers, or social security numbers) at any stage of our hiring process. Our legitimate recruitment is entirely free for candidates.

• Strong understanding of Layer 3 networking: IP routing, tunneling (WireGuard, IPsec), TCP/UDP, socket programming
• Experience building distributed or networked systems (SDN/SD-WANs, VPNs, routing daemons, network control planes, or similar)
• Understanding of cryptographic fundamentals: symmetric/asymmetric encryption, digital signatures, certificate chains, TLS
• Experience designing or operating PKI systems (certificate authorities, ACME, EST, or custom issuance protocols)
• Familiarity with asynchronous programming models
• Comfort with network debugging tools (tcpdump, Wireshark, iproute2)
• Must be eligible to obtain and maintain an active U.S. Secret security clearance, * Experience with FIPS 140-2/140-3 validated cryptographic modules
• Experience with post-quantum cryptography (PQC) algorithms, migration strategies, and CSNA 2.0 compliance.

• Experience with dynamic routing protocols (OSPF, BGP) or software-defined networking
• Experience integrating with tactical radio systems or military waveforms
• Familiarity with Kubernetes networking (CNI plugins, service mesh, network policies)
