Job summary

Anduril Industries is seeking a Software Engineer for the Tactical Networking Team to design and operate Layer 3 networking across DDIL environments, integrating radio, satellite, and wired transports.

You will build PKI-enabled, zero-trust networking, with real-time observability, and support mission-critical data flows under bandwidth constraints while ensuring secure, scalable deployment in field conditions.

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, TCP/UDP.
• 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.
• 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).
• 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.
