Field Applications Engineer

The modern battlefield has changed. Cheap, autonomous suicide drones have turned the tactical advantage upside down, and the world is looking for a solution. At 9 Mothers, we aren’t just "innovating"—we are building the shield.

Backed by top-tier investors, we develop AI powered machines designed to intercept and neutralize Group 1/sUAS threats in real-time. Our flagship product is a low-power, counter-drone system built for the edge—on vehicles, at bases, or in a soldier's pack.

While others build for "awareness" or "long-term research," we build for the immediate survival of those in harm’s way. We are a team of hackers, engineers, and mission-driven builders who value field-ready capability over polished slide decks. If you want to see your code or hardware in the field next month—not next year—this is your playground.

We are seeking a Field Applications Engineer (Demo Engineer) to serve as the critical bridge between our engineering lab and real-world deployment. You will be the hands-on expert responsible for bringing our autonomous c-sUAS platforms to life in front of active-duty end users, government partners, and key stakeholders.

From flashing software builds and calibrating multi-sensor payloads in the lab to operating systems and troubleshooting hardware live on the test range, you ensure zero-fail execution when the pressure is on.

• • Prior experience with robotics, Unmanned Aerial Systems (UAS), counter-UAS (c-UAS), or defense range operations.

  • Familiarity with thermal/IR optics, RF sensors, or embedded Linux environments (e.g., NVIDIA Jetson).

  • Prior defense startup experience or military background in range safety/flight test operations.

  • Security clearance or the ability to obtain one.

  • A passion for building or engineering robotics or electronics as a hobby.
