About The Team
The Sentry Tower Software team develops robotic systems that provide force protection capabilities, monitoring the perimeter of secure areas, land or sea, for approaching people, vehicles, and vessels.
About the Job
Every Sentry Tower we ship, across Counter-Intrusion and Air Defense, boots from a common software platform: a NixOS-based overlay that defines the base images, the system services, the compute configuration for each hardware generation, and the network topology that ties the tower’s payloads together. That platform is the foundation the entire product line stands on, and we are looking for a Senior Software Engineer to own it.
What You’ll Do
- Own the shared base of our NixOS overlay: system modules, compute platform definitions, common tower services, and the image definitions that every product variant composes from.
- Own the tower network topology end to end: VLAN and subnet allocation, bridging, link ranking and failover across heterogeneous backhaul, NAT and firewall policy, and the physical-port-to-payload mapping for each carrier board.
- Define and enforce the integration contract that business line teams use to add network-attached payloads.
- Drive the consolidation of legacy, per-product configurations into the common overlay.
- Support and extend our real-time messaging layer as services migrate from the legacy pub-sub bus to its next-generation replacement.
- Debug problems that cross every layer at once: kernel and device tree, systemd unit ordering, Nix evaluation, link-layer configuration, and the sensor daemons on top.
Required Qualifications
- 4+ years of professional software engineering with substantial time in Linux systems, embedded platforms, or infrastructure work.
- Deep, practical networking knowledge: VLANs, bridging, routing, DHCP, multicast, NAT, and firewalling.
- Strong experience with declarative configuration management and reproducible builds (Nix/NixOS preferred; Bazel, Buildroot, Yocto, Terraform, Ansible, Pulumi as substitutes).
- Proficiency in Rust or C++.
- Comfort operating and troubleshooting real hardware.
- US person status required, with eligibility to obtain and maintain a US security clearance.
