Field Software Engineer
Job Description
Description:Sensors don't fail in the lab — they fail in the field, usually at the worst possible moment, in front of the customer. That's where you come in.OKSI builds electro-optical, infrared, and autonomous sensor systems that the Department of War depends on in the field. As our Field Support Engineer, you'll be the person who gets those systems running when it matters — traveling to test ranges and customer sites, diagnosing problems other people can't, and representing OKSI's engineering directly to the people who use what we build. This is a hands-on, high-trust, high-visibility role: not an entry-level position, and not a desk job.At OKSI, we believe in owning problems end to end — from first concept through final delivery. We see it through! If you're looking for a place where you can take real ownership, stretch your skills, a place to grow your career while owning meaningful, mission-driven work, this is where you belong!Why This Role
Direct impact: your fixes and field reports shape how OKSI's next systems get built — you'll work shoulder-to-shoulder with the same engineers who designed the hardware and software you're supporting.
Ownership from day one: as the on-site technical authority, you make the calls that keep a deployment running, without layers of process to work through.
Variety: no two deployments look the same — one week it's an embedded software issue, the next it's a mechanical fix in the field, the next it's briefing a government program office.
Small-company visibility: at a small company, your work is seen and known — not buried in a large program's org chart.What You Will Do
