Full Job Description
Location: Onsite — Austin, TX Employment Type: Direct Hire, Full Time Job Title: Lead Electrical Engineer About 9 Mothers 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. Why 9 Mothers? 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. Position Summary We are seeking a Lead 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. Essential Duties - Board Design & Prototyping: Lead the end-to-end design of complex, multi-layer PCBs, including schematic capture and layout. - Acoustic Integration: Work closely with the Acoustic team to integrate microphone arrays, ensuring signal integrity for low-noise, multichannel audio acquisition. - Power Management: Design and optimize power distribution and control systems to support
