Senior Software Engineer, Tactical Networking

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.ABOUT THE TEAMThe Software Platform organization is seeking a Software Engineer to join Anduril’s Tactical Networking Team. We build and operate the Layer 3 networking infrastructure that connects Anduril's autonomous systems and operators across denied, degraded, intermittent, and limited (DDIL) network environments. We own the full network lifecycle — secure VPN tunnels over tactical radios and satellite links, PKI and cryptographic identity for every node in the mesh, intelligent QoS traffic orchestration, and real-time network observability and management.Security is foundational to everything we build. Every link in the Lattice mesh is authenticated and encrypted, backed by a purpose-built PKI that handles certificate issuance, rotation, and revocation across thousands of intermittently connected nodes. We design to meet rigorous government compliance standards while remaining operationally practical for warfighters in the field.WHAT YOU'LL DODesign and implement Layer 3 networking for DDIL environments — VPN tunnel management, dynamic routing, and multi-path failover across tactical radios, satellite, and wired transportsBuild radio integration layers that abstract diverse tactical waveforms behind a unified networking interfaceDesign QoS scheduling and traffic shaping to ensure mission-critical data flows under severe bandwidth constraintsBuild network management and orchestration systems for real-time topology configuration and adaptationArchitect PKI infrastructure for the Lattice mesh — certificate authorities, automated issuance/renewal, revocation (CRL/OCSP), and secure node bootstrappingDesign certificate lifecycle management that handles rotation and re-keying across nodes with intermittent connectivityImplement zero-trust identity verification across all mesh communication pathsTreat 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 statusDebug complex networking issues from packet captures on deployed assets to cloud infrastructureREQUIRED QUALIFICATIONS3+ years of professional software engineering experienceProficiency in a systems programming language (Rust, C, C++, or Go)Strong understanding of Layer 3 networking: IP routing, tunneling (WireGuard, IPsec), TCP/UDP, socket programmingExperience 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, TLSExperience designing or operating PKI systems (certificate authorities, ACME, EST, or custom issuance protocols)Familiarity with asynchronous programming modelsComfort with network debugging tools (tcpdump, Wireshark, iproute2)Must be eligible to obtain and maintain an active U.S. Secret security clearancePREFERRED QUALIFICATIONSExperience with FIPS 140-2/140-3 validated cryptographic modulesExperience with post-quantum cryptography (PQC) algorithms, migration strategies, and CSNA 2.0 compliance.Familiarity with HSMs or TPMs for key protectionExperience with dynamic routing protocols (OSPF, BGP) or software-defined networkingExperience integrating with tactical radio systems or military waveformsFamiliarity with Kubernetes networking (CNI plugins, service mesh, network policies)US Salary Range$191,000—$253,000 USDThe salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only.
