Senior Power Electronics Engineer

About the Company

We are an innovative robotics company building the next generation of autonomous robots to transform how AI infrastructure is constructed, maintained, and operated.

As demand for AI computing accelerates, the physical infrastructure supporting it is struggling to keep pace. Data centers still rely heavily on manual labor for installation, cabling, commissioning, and maintenance. We're changing that.

We're developing purpose-built, high-precision autonomous robots that accelerate infrastructure deployment, improve reliability, and bring greater efficiency and traceability to complex physical operations.

Our approach combines advanced robotics, AI, and rigorous systems engineering to build machines designed for real-world performance—not just demonstrations.

With approximately 20 employees, our vertically integrated team brings mechanical, electrical, firmware, software, and machine learning engineering together under one roof. Our in-house machine shop enables rapid prototyping, testing, and iteration.

We're building the future of robot-powered infrastructure, and we're looking for exceptional engineers who want to help make it happen.

About the Opportunity

We're seeking a Senior Power Electronics Engineer to take end-to-end ownership of the electrical power architecture powering our autonomous robotic systems.

This is a highly hands-on individual contributor role for an engineer who thrives on solving complex technical challenges, building real hardware, and seeing their designs through production.

You'll work across power conversion, motor drives, electrical integration, PCB design, and system-level architecture, collaborating closely with mechanical, firmware, and software engineers.

Rather than receiving detailed specifications, you'll be given engineering objectives and the autonomy to determine the best solution.

From defining requirements and evaluating design tradeoffs to building prototypes, debugging hardware, and preparing systems for production, you'll own the entire engineering lifecycle.

This opportunity is ideal for someone who loves engineering and wants to remain deeply technical while making a significant impact on the products they build.

What You'll Do

• Own the complete electrical power architecture of autonomous robotic systems, including power distribution, conversion, protection, and integration.
• Design, develop, and validate power electronics, including DC/DC converters, motor drives, gate drivers, power distribution boards, and protection circuitry.
• Lead schematic design, PCB layout, board bring-up, debugging, testing, and validation of power and mixed-signal electronics.
• Develop and integrate electrical systems supporting motors, actuators, sensors, instrumentation, and industrial control components.
• Evaluate architectural tradeoffs and select components based on performance, reliability, cost, safety, and manufacturability.
• Collaborate with mechanical, firmware, and software engineers to ensure seamless integration across complete robotic platforms.
• Take designs from concept through production, partnering with PCB manufacturers, suppliers, and contract manufacturers to improve manufacturability and production yield.
• Establish electrical safety practices and design for EMI/EMC, high-voltage safety, and applicable product certifications.
• Lead electrical design reviews, maintain technical documentation, and establish engineering standards as the company scales.
• Troubleshoot complex hardware and system-level issues, identifying root causes and implementing reliable, practical solutions.

What We're Looking For

• Bachelor's or Master's degree in Electrical Engineering or a closely related technical field.
• Approximately 3–10 years of relevant electrical engineering experience, with demonstrated ownership of complex hardware projects. Exceptional engineers with fewer years of experience and substantial hands-on ownership are encouraged to apply.
• Proven experience taking power electronics designs from concept through production.
• Strong understanding of power electronics fundamentals, including buck, boost, flyback, and other DC/DC converter topologies.
• Experience selecting and sizing power components, including MOSFETs, gate drivers, controllers, magnetics, capacitors, and sensing circuits.
• Hands-on motor drive design experience involving gate drivers, H-bridges, BLDC/PMSM motors, and field-oriented control.
• Proficiency in PCB schematic capture, layout, hardware bring-up, and debugging of power and mixed-signal circuits.
• Understanding of thermal design, PCB-level EMC considerations, electrical protection, and common power electronics failure modes.
• Demonstrated experience contributing to or owning the electrical architecture and integration of a complete hardware system.
• Strong analytical and troubleshooting skills, with the ability to independently define requirements and solve ambiguous engineering problems.
• Willingness to work onsite five days per week in San Francisco.

Nice to Have

• Experience developing robotics, industrial automation, automotive, aerospace, or other motor-driven electromechanical systems.
• Previous experience in an early-stage startup or small, fast-moving hardware engineering team.
• Experience with battery-powered systems, high-power electrical systems, and high-voltage safety practices.
• Familiarity with EMI/EMC compliance testing, electrical safety standards, and product certification.
• Embedded firmware development experience using C, C++, or Rust.
• Experience with motor control firmware and industrial communication protocols.
• Proficiency with power electronics simulation tools such as LTspice or PLECS.
• Experience working with contract manufacturers and bringing complex electronic products into volume production.

What Makes You Successful Here

You are a builder at heart. You enjoy taking ownership of challenging engineering problems and turning ideas into reliable, functioning hardware.

You are equally comfortable designing circuits, debugging boards in the lab, and making system-level architectural decisions.

You understand when to build something custom and when an existing solution is the smarter engineering choice.

You take pride in your work, care deeply about quality, and recognize that successful hardware development requires collaboration across multiple engineering disciplines.

Most importantly, you want to remain hands-on and continue growing as a technical expert rather than moving into management.

Why Join Us?
