Senior Software Engineer, Tactical Networking

Highlights

• Build Layer 3 mesh networking that connects autonomous systems in DDIL environments.
• Build QoS scheduling to keep mission-critical data flowing under tight bandwidth.
• Architect PKI and zero-trust identity securing every link in the Lattice mesh.

Ideal candidate

A systems-minded engineer energized by secure, resilient networking for contested environments. You care about operational impact, love debugging complex distributed systems, and thrive owning infrastructure end to end for warfighters.

Requirements

• 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
