Nimble Robotics is an AI robotics company building autonomous supply chain solutions. The company has raised over $220M at a $1B+ valuation and formed a strategic alliance with FedEx to develop a national network of autonomous warehouses. The founding team includes AI researchers from Stanford and Carnegie Mellon, with board advisors including Fei-Fei Li (Chief Scientist of AI at Google), Marc Raibert (founder of Boston Dynamics), and Sebastian Thrun (founder of GoogleX and Waymo).
As a Senior Electrical Engineer specializing in Power Electronics, you will design and own motor controller boards and power distribution boards for robotic platforms, from architecture through production validation. Your responsibilities include:
- Design motor controller boards, power distribution boards, and high-power electronics for robotic systems
- Own power-stage architecture, schematic capture, component selection, and PCB layout for MOSFETs, gate drivers, current sensing, protection circuits, and thermal management
- Define grounding, power sequencing, fault handling, and interfaces between batteries, motors, sensors, and compute systems
- Develop drive electronics and commutation interfaces with control firmware
- Collaborate with firmware, controls, mechanical, and software engineers on system integration and testing
- Write and execute validation plans covering efficiency, thermal performance, transient response, fault conditions, EMC/EMI, and environmental limits
- Diagnose power integrity, motor control, thermal, and reliability failures in lab and deployed robots
- Shepherd designs through DFM, certification, production testing, and manufacturing ramp
- Drive the team's electrical design best practices
You will work in a high-intensity, fast-moving environment with a team of world-class engineers focused on building legendary robotics technology.
