Role Overview

As a Senior Electrical Engineer, you will design motor controller boards and power distribution boards for our robotic platforms. You will own the work from architecture and component selection through validation and production. You will work with mechanical, firmware, controls, and software engineers to build hardware that performs under real operating conditions.
Key Responsibilities

• Design motor controller boards, power distribution boards, and other high-power electronics for robotic platforms
• Own power-stage architecture, schematic capture, component selection, and PCB layout reviews for MOSFETs, gate drivers, current sensing, protection circuits, and thermal management
• Define grounding, power sequencing, fault handling, and interfaces among batteries, motors, sensors, and compute systems
• Develop drive electronics and interfaces to commutation with control firmware
• Work with firmware, controls, mechanical, and software engineers to integrate and test each system
• Write and run validation plans for efficiency, thermal performance, transient response, fault conditions, EMC/EMI, and environmental limits
• Diagnose power integrity, motor control, thermal, and reliability failures in the lab and on deployed robots
• Take designs through DFM, certification, production testing, and manufacturing ramp
• Drive team's electrical design best practices

Qualifications

• Bachelor's, Master's degree, or PhD in Electrical Engineering or a related field
• 4+ years designing power electronics, motor drives, or high-current embedded hardware
• Experience designing motor controller boards, power distribution boards, DC/DC converters, inverters, or related power systems
• Knowledge of power semiconductors, gate drives, current and voltage sensing, magnetics, protection circuits, and control loops
• Experience with thermal analysis, power integrity, grounding, creepage and clearance, and high-current PCB layout
• Proficiency with Altium, OrCAD, KiCad, or a comparable PCB design tool
• Ability to run circuit, power electronics, and thermal simulations to validate designs before hardware testing
• Familiarity with embedded systems and protocols such as SPI, I2C, CAN, and UART
• Lab experience with oscilloscopes, current probes, electronic loads, power analyzers, and thermal cameras
• A record of shipping hardware products to production
• Knowledge of EMC/EMI design, functional safety, and regulatory compliance

Preferred Qualifications

• Power electronics experience in electric vehicles, mobile robots, industrial robotics, or autonomous systems
• Experience with three-phase BLDC/PMSM motor drives, field-oriented control, regenerative braking, and motor characterization
• Experience with batteries, battery management systems, pre-charge circuits, contactors, fusing, and high-current or high-voltage distribution
• Knowledge of embedded firmware, motor-control algorithms, and low-level software interfaces
• Experience developing high-reliability or safety-critical systems
• Familiarity with DFM, DFA, production testing, and manufacturing processes
• A record of learning new design methods and applying AI tools to component research, circuit analysis, design reviews, documentation, or debugging

Compensation

The pay range for this position at the start of employment is expected to be between $180,000 and $230,000/year. Your exact offer may vary depending on multiple individualized factors, including job-related knowledge, skills, and experience. In addition to cash compensation, this position will also receive generous equity for this position.
