About The Position

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.

Requirements

Proven track record of shipping real-world physical systems.
Mastery of Altium, KiCad, or similar for high-density PCB design and power electronics.
Understanding design to meet general EMC and electrical safety requirements.
Hands-on experience integrating digital audio interfaces (I2S, TDM, PDM) and high-speed communication protocols.
A strong bias toward action and shipping; comfortable getting your hands dirty in the lab or the field.
U.S. Citizenship and the ability to pass a background check

Nice To Haves

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.

Responsibilities

Lead the end-to-end design of complex, multi-layer PCBs, including schematic capture and layout.
Work closely with the Acoustic team to integrate microphone arrays, ensuring signal integrity for low-noise, multichannel audio acquisition.
Design and optimize power distribution and control systems to support high-torque motors and edge-compute hardware like NVIDIA Jetsons.
Create robust electrical designs which maintain functionality in environments with extreme temperature, humidity, and mechanical vibration.
Develop robust circuits for motor controllers, sensor interfaces, and communication protocols (e.g., CAN bus and EtherCAT) that survive harsh environmental conditions.
Utilize oscilloscopes, logic analyzers, and rework stations to identify and fix hardware-level failures during rapid iteration cycles.
