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. Our products leverage advanced sensor fusion and autonomy to seamlessly render activity in the environment to Lattice’s common operating picture. Sentry Towers are robotic systems: motors, cameras, radars, radios, and sensor boards, running on NVIDIA Jetson compute in the field. Verifying that a system like this works means accounting for physical actuation, real sensor data, and hardware that fails in ways no unit test anticipates. We’re hiring a Senior Software Engineer to own our simulation and hardware test infrastructure and make automated, whole-system testing the default for everything we ship. A regression that escapes here does not surface on a developer’s laptop. It surfaces on a tower at a site someone has to fly to, guarding a perimeter that does not pause while we debug. You will work across both halves of the problem. Our software-in-the-loop environments are declaratively defined multi-node virtual towers, complete with a simulated ground control station, synthetic sensor feeds, and a game-engine-driven world, which lets us run whole-system scenarios in CI with no hardware attached. Our hardware-in-the-loop side drives real Jetson-based towers through a board test server: provisioning them over the network, flashing firmware, installing full system images, and reporting results back through our CI pipeline on a nightly and weekend cadence. Both foundations are in place and working, so you are inheriting infrastructure rather than starting from nothing. What does not exist yet is most of what sits on top: the functional test suites, the scenario library, and the diagnostic tooling that turn a booting tower into a verified one are yours to design. Firmware integration, compute platform bring-up, and both our Air Defense and Counter-Intrusion business lines depend on this capability, and what you build becomes the standard they test against. Test infrastructure is a job where the wins are invisible and the failures are loud. You will spend real time on work nobody asks for by name: chasing intermittent failures to root cause instead of retrying them, waiting on hardware that is scarce and shared, and rebuilding coverage when a compute generation changes underneath you. The measure of the role is bugs that never reach a tower, which means much of your best work leaves no trace anyone thanks you for.
