Lead Electrical Engineer responsible for electrical architecture, high-speed PCB design, and sensor integration for ground-based interceptor platforms.
Requirements
- Experience: Proven track record of shipping real-world physical systems.
- Technical Depth: Mastery of Altium, KiCad, or similar for high-density PCB design and power electronics. Understanding design to meet general EMC and electrical safety requirements.
- Bias for Action: A strong bias toward action and shipping; comfortable getting your hands dirty in the lab or the field.
- Compliance: U.S. Citizenship and the ability to pass a background check
Nice to have
- 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.
Conditions
- Meaningful Early Equity: You aren't just an employee; you are a foundational owner. Your contributions directly drive the value of your stake in the company.
- Direct Roadmap Influence: Forget the bureaucracy of big defense. You will have a seat at the table, directly shaping our product and technology trajectory from day one.
- Mission-Critical Work: We don't build for "what if." We build systems the Department of War actively needs to counter immediate, real-world threats.
- The Builder's Playground: Work in a brand-new lab fully optimized for rapid prototyping, equipped with NVIDIA Jetsons, high-end scopes, and 3-D printers.
- 100% Employer-Paid Premiums: We cover 100% of your medical, dental, and vision insurance premiums and cover 50% of healthcare premiums for your dependents.
- Unlimited PTO: We value results, not clock-watching. Take the time you need to stay sharp and recharge.
- Zero Red Tape: You report to the founders. You have the autonomy to make technical decisions that would take months of committee approval at a larger firm.
- Austin-Based Culture: Join an onsite team in Austin, TX, where we prioritize high-bandwidth collaboration and rapid field-testing.
- Relocation Assistance: We want the best talent in the room. If you aren't in Austin yet, we’ll help you get here, to make your transition to the Silicon Hills seamless.
Other
- Location: Onsite — Austin, TX
- Employment Type: Direct Hire, Full Time
- Job Title: Staff Electrical 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 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.
- 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 high-torque motors and edge-compute hardware like NVIDIA Jetsons.
- Environmental Ruggedness: Create robust electrical designs which maintain functionality in environments with extreme temperature, humidity, and mechanical vibration.
- Circuit Design: Develop robust circuits for motor controllers, sensor interfaces, and communication protocols (e.g., CAN bus and EtherCAT) that survive harsh environmental conditions.
- Hardware Debugging: Utilize oscilloscopes, logic analyzers, and rework stations to identify and fix hardware-level failures during rapid iteration cycles.
- Virtual interview with Director of Mechanical Engineer and Director of Mechatronics (45 min via MS Teams)
- Paid take-home ($500, ~8 hours)
- Team will review your solution to the take-home assignment
- Interview with co-founder (could be in-person or virtual, dependent on location)
- In-person visit to Austin and/or Offer
