Software Engineer, Platform Overlay & NetworkingActive$254K

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. We live in a world where security officers are increasingly overwhelmed by sensor data feeds.

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, so their additions extend the platform instead of diverging from it.

• Drive the consolidation of legacy, per-product configurations into the common: overlay, with build-time checks that keep them from drifting back apart.

• Support and extend our real-time messaging layer as services migrate from the: legacy pub-sub bus to its next-generation replacement, including the topic and schema contracts that define who owns which data.

• 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.
