Electrical Engineer, Senior

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 Senior Electrical Engineer to own the electrical architecture of our ground-based interceptor platforms. You will be responsible for the "nervous system" of our machines, from high-speed PCB design to complex sensor integration. This role is for a builder who can prototype a board in the morning and debug it in the field by the afternoon. You will play a critical role in integrating our custom acoustic sensing arrays and ensuring our power systems can handle high-speed tracking and rapid-response turret actuation. You will maintain ownership of electrical designs from concept to production.

• Prior experience with DoD codes and standards as pertinent to electrical systems

• Experience with power systems for high-speed gimbal or turret systems.

• Security clearance or the ability to obtain one.

• Passion for building robots or engineering projects as a hobby.
