## Description

The Software Platform organization at Anduril is seeking a Senior Software Engineer to join the Tactical Networking Team. The team builds and operates the Layer 3 networking infrastructure that connects Anduril's autonomous systems and operators across denied, degraded, intermittent, and limited (DDIL) network environments.

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

Required 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

Preferred Qualifications:

- Experience with FIPS 140-2/140-3 validated cryptographic modules

- Experience with post-quantum cryptography (PQC) algorithms, migration strategies, and CSNA 2.0 compliance

- Familiarity with HSMs or TPMs for key protection

- Experience with dynamic routing protocols (OSPF, BGP) or software-defined networking

- Experience integrating with tactical radio systems or military waveforms

- Familiarity with Kubernetes networking (CNI plugins, service mesh, network policies)

Benefits: Anduril offers a comprehensive, competitive benefits package (available at little to no cost to employees) that ensures you're supported in health, recovery, and whatever comes next.

Salary Range: $191,000-$253,000 USD
