Job summary

Greywright Inc. is seeking a Senior Networks Engineer to lead the build-out, improvement, and operation of networks connecting autonomous systems, ground stations, and operators.

You will ensure secure, reliable links across LOS radios and backhaul, with policy-based routing and resilient failover. The ideal candidate has 8+ years in network engineering, strong TCP/IP, VPN expertise, and hands-on experience with LOS radio networks and secure tunnels.

Qualifications

• B.S. in Electrical or Computer Engineering, CS, or related field.
• 8+ years of network engineering experience, incl. production networks.
• Hands-on with LOS radio networks and multi-path backhaul fusion.
• Deep knowledge of network security: firewalls, segmentation, and design.
• VPN technologies (IPsec, WireGuard, OpenVPN) and encrypted tunneling.
• Proven experience optimizing lossy, high-latency networks for continuous control.
• Strong TCP/IP, routing (BGP, OSPF), QoS, and traffic shaping.
• Linux networking and scripting (Python, Bash) for automation.
• Experience building enterprise or lab networks with switching/routing/Wi‑Fi.
• Willingness to travel up to 50%.
• ITAR/EAR data access; U.S. person status required.

Responsibilities

• Own and harden end-to-end network architecture for Greywright's autonomous systems.
• Design and operate line-of-sight radio networks, including mesh and point-to-multipoint links.
• Fuse multiple backhaul paths with bonding, link aggregation, and policy-based routing.
• Engineer networks for lossy, high-latency, and intermittent links so command and control stays continuous.
• Set traffic prioritization and QoS so critical data gets through first.
• Design and run secure VPN and encrypted tunnel architectures across all links.
• Own network security: segmentation, firewalls, access control, key management, and monitoring.
• Expand monitoring, telemetry, and diagnostics for link health, and lead troubleshooting.
• Test network performance under realistic and degraded conditions with the test and autonomy teams.
• Collaborate with the autonomous systems architect and OEM partners on network interfaces.
• Stand up and maintain development and operational networks, including office, lab, hardware-in-the-loop, test-site connectivity.
• Implement network controls that protect ITAR/EAR data.
