About the role

Senior Software Engineer role focused on Layer 3 networking for DDIL environments, building secure, observable, and scalable networking for Anduril’s autonomous systems and operators.

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

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
