Senior Tactical Networking Software Engineer - Equity Eligible

Anduril-1; Seattle (WA); On-site; USD 152,000 - 253,000; Full time

Job summary

Anduril Industries in Seattle, WA, seeks a Senior Software Engineer to design and implement Layer 3 networking for DDIL environments, with VPNs, routing, and multi-path failover across radios, satellites, and wired transports. The role emphasizes secure PKI, zero-trust identity, and real-time observability.

Candidates should have strong systems programming skills and a US security clearance. The position offers work on a mission-critical defense platform, with opportunities to shape secure,

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, sockets.
• Experience building distributed or networked systems (SDN/SD-WANs, VPNs, routing daemons, 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.
• 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.
