About the Role

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.

Responsibilities

  • Lead live, dynamic flight and target-tracking demonstrations in field environments, operating autonomous counter-drone systems flawlessly under high-stakes conditions.
  • Prepare, assemble, and check complex autonomous hardware and edge-compute systems prior to field tests and customer demonstrations.
  • Perform precise hardware and sensor alignment, including boresighting, thermal/EO camera focusing, lens calibration, and multi-sensor orientation.
  • Flash latest software builds, test system stability, perform integration tests, and ensure firmware/software readiness for field trials.
  • Diagnose and resolve unexpected hardware, software, networking, and sensor issues on the fly with minimal downtime during field trials.
  • Serve as the direct link between field reality and R&D, capturing detailed telemetry, edge cases, and user feedback to inform engineering rapid iteration cycles.

Requirements

  • Demonstrated experience deploying, operating, or troubleshooting complex hardware/software systems in real-world or live-fire test range environments.
  • Practical experience with optical/camera calibration (focus, boresighting), sensor alignment, and field validation techniques.
  • Proficient in Linux CLI environments, firmware/software flashing tools, and basic networking/telemetry debugging.
  • Experience with harness assembly, field repair, cable building, and multimeters/oscilloscopes for quick edge-side hardware fixes.
  • Willingness to travel to outdoor testing sites and demonstration ranges; comfortable working outdoors in varying terrain and weather conditions.
  • This position requires access to export-controlled information under ITAR. Only U.S. citizens are permitted.
  • Must be willing to submit to a background check.

About the Company

  • 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.
