Field Applications Engineer

Location: Onsite — Austin, TX

Employment Type: Direct Hire, Full-Time

Job Title: Field Applications Engineer (Demo 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.

• Demo Operations & Execution: Lead live, dynamic flight and target-tracking demonstrations in field environments, operating autonomous counter-drone systems flawlessly under high-stakes conditions.

• System Preparation & Hardware Setup: Prepare, assemble, and check complex autonomous hardware and edge-compute systems prior to field tests and customer demonstrations.

• On-Site & Field Calibration: Perform precise hardware and sensor alignment, including bore sighting, thermal/EO camera focusing, lens calibration, and multi-sensor orientation.

• Software Deployment & Validation: Flash latest software builds, test system stability, perform integration tests, and ensure firmware/software readiness for field trials.

• Rapid Field Troubleshooting: Diagnose and resolve unexpected hardware, software, networking, and sensor issues on the fly with minimal downtime during field trials.

• Feedback Loop: 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.
