Robotics Motor Drive Engineer for Home Robots

Weave Robotics, Inc.; San Francisco (CA); On-site; USD 140,000 - 190,000; Full time

Job summary

Weave builds and deploys some of the first bimanual robots operating in customer homes. In this role, you'll own motor controllers and the motors they drive, collaborating with our firmware, mechanical, and manufacturing teams to deliver actuators that are powerful, precise, safe, and quiet enough to live in a home.

Located in San Francisco, this on-site role focuses on turning boards and motors into reliable, production-ready hardware, from architecture through bring-up to production, with an

Qualifications

• 3+ years designing motor drive or power electronics hardware.
• Solid grounding in BLDC/PMSM fundamentals.
• Hands-on FOC: current loops, SVPWM, sensor calibration.
• PCB design in multilayer boards (Altium) from schematic to bring-up.
• Experience with EtherCAT, CAN/CAN FD, SPI, I2C or similar buses.
• Firmware bring-up in embedded C or Rust.
• Hands-on debugging with oscilloscopes, current probes, and electronic loads.

Responsibilities

• Design motor controller boards: gate drive, power stage, current sensing, MCU, and protection circuitry for our in-house actuators, across different voltage and current requirements, from schematic through layout, bring-up, validation, and production.
• Own the feedback inputs: the interfaces the control loops live on: encoders, halls, phase voltage sensing, and thermistors, including signal conditioning, noise immunity next to a switching stage, and the timing and synchronization that current sampling requires.
• Bring up and tune FOC: commutating new motor and board combinations, tuning current loops, calibrating encoder offsets, identifying motor parameters, and verifying torque accuracy and smoothness on the dyno, partnering with the firmware team.
• Design for quiet and efficiency: switching behavior, PWM strategy, thermal design, EMI/EMC for a consumer product that sits near people.
• Support production: Drive DFM/DFT, panelization, test point and programming strategy, end-of-line test coverage, and per-unit calibration routines.
