Senior Power Electronics Engineer
Confirmed on the employer's own hiring board on Nov 9, 2026. First seen by Alion on Oct 31, 2026. Gradient Robotics scores B on the Alion truth index.
About the Company
The datacenter buildout is the largest industrial project in human history. Gradient builds the autonomous robots that make it possible.
Partnered with the world's largest AI infrastructure companies and backed by the industry's best investors, we move fast and build full-stack systems that matter.
About the role
We’re looking for a Senior Power Electronics Engineer to own the electrical and power architecture of Gradient’s robots: how they’re powered, how they sense, and how they’re controlled. This is an end-to-end ownership role with power electronics at its core. You’ll define our power architecture from input power down to the motor drives and sensors, run the trade studies that set our design direction, and take boards from schematic through bring-up to production. You’ll partner closely with mechanical and software teams, and the standards you set will shape every machine we ship. The electronics you design become the nervous system of our robots.
Responsibilities
Own power architecture end-to-end: define power distribution, conversion, and protection across our robots, and run the trade studies behind key design decisions
Systems design
Design and validate power electronics, including DC/DC converters, motor drives, gate drivers, power distribution boards, and protection circuitry, from schematic and layout through bring-up and test
Own instrumentation and controls: partner with mechanical engineers on sensing and actuation, build electronics with custom PCBs or industrial components, and write firmware that gives software a reliable control interface
Take designs to production: drive thermal performance and manufacturability, and partner with board vendors and contract manufacturers on yield
Own electrical safety and compliance: set high-power and high-voltage safety practices for our lab and build floor, design for compliance from the start (EMI/EMC, harmonics, arc flash, product safety), and take our robots through testing and certification so they’re safe to install, operate, and service in customer facilities
Set the electrical bar: lead design reviews, keep documentation and cross-team compatibility current, and mentor engineers as the team grows
Minimum Qualifications
BS or MS in Electrical Engineering or a related field
5+ years of electrical design experience, including power electronics designs you’ve taken to production
Deep power electronics fundamentals: converter topologies (buck, boost, flyback, etc.), sizing discrete components (controllers, gate drivers, MOSFETs, magnetics, capacitors, sensing), protection circuitry, and common failure modes
Motor drive design experience: gate drivers, H-bridges, BLDC/PMSM, FOC
Hands-on PCB design and layout for power and mixed-signal boards, including thermal and layout-level EMC considerations
Experience with high-power and high-voltage safety principles and best practices, EMI/EMC mitigation and compliance testing, and taking hardware through safety certification
A track record of defining requirements yourself and driving cross-system problems to resolution when the spec is unclear
Strong hardware debugging: you know how to attack a board- or system-level problem, document it, and fix it fast
An obsession with quality: you want projects not just done, but done well
Able to work on-site in San Francisco 5 days/week (6 days/week if needed during crunch time), embedded in the team
Preferred Qualifications
Experience at a robotics, industrial automation, automotive, or other motor-driven hardware company
Firmware development experience (embedded C/C++ or Rust, motor control, communication protocols)
Experience simulating power electronic circuits (LTspice, PLECS, or similar)
Comfort using AI tools to multiply your own output
If you’ve built power hardware that shipped and you want to own the electrical side of a new class of robots, we want to hear from you. It’s okay if your qualifications don’t match every line here. We’re aggressively trying to learn everything we can about robotics, and you’ll help set that direction.
