Senior Software Engineer, Tactical Networking & Secure Mesh

Anduril-1; Costa Mesa (CA); On-site; USD 191,000 - 253,000; Full time

Job summary

Anduril Industries in California is seeking a Senior Software Engineer for the Tactical Networking team to design and implement Layer 3 networking across DDIL environments, integrating VPN, dynamic routing, and multi-path failover for radios, satellites, and wired transports.

You will build network management, PKI infrastructure, and zero-trust identity across the mesh, with observability via Prometheus, Grafana, and eBPF, plus hands-on debugging from field assets to cloud.

Qualifications

• 3+ years of professional software engineering experience.
• Proficiency in a systems programming language (Rust, C, C++, or Go).
• 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.

Responsibilities

• 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
