What We're Looking ForWe develop custom servo actuators, compute, networking, cameras, sensors, and power electronics for our robots. These systems need to be performant, reliable, cost-effective, and tightly integrated with the rest of the robot.
We are looking for a senior electrical engineer to own the robot's power electronics and power distribution architecture. This includes the battery management system, bus voltage switching, e-stop integration, precharge, cabling, motor inverters, and EMI mitigation.
You will be responsible for defining requirements, making system-level architecture decisions, and taking designs from concept through bring-up, testing, and deployment. You will also work closely with junior engineers and external layout resources to execute designs.
Some of the problems you may work on include:
- Miniaturizing motor drives by reducing bus capacitance and switching-stage size without sacrificing efficiency or creating EMI problems
- Designing the power system safety architecture, including safe startup, shutdown, fault handling, and battery hot-swapping
- Designing and validating a custom battery management system
- Improving motor inverter performance, reliability, thermal performance, and packaging
- Diagnosing and mitigating conducted and radiated EMI across the robot
We love engineers who have built systems they are genuinely proud of, whether that is a shipped product, a difficult technical project, or something they built outside of work.
Required Qualifications- Strong electrical engineering fundamentals
- Deep experience designing power electronics systems, ideally in the ~48V range
- Experience with motor inverters, motor drives, or similar high-current switching systems
- Strong PCB design, board bring-up, test, and debug skills
- Comfortable debugging power electronics with scopes, power supplies, current probes, and other lab equipment
- Strong understanding of system-level tradeoffs across electrical, firmware, mechanical, thermal, and cost constraints
- Ability to independently define technical requirements and make architecture and design decisions
- Experience taking complex electrical designs from concept through prototype and validation
- Strong communication skills and ability to lead technical work across multiple contributors
- BS or higher in Electrical Engineering or a related field
Bonus Qualifications- Experience with low-voltage power electronics for robotics, electric aircraft, EV subsystems, industrial automation, or servo systems
- Motor physics and motor control experience
- Control systems or stability analysis experience
- Battery management system design
- Power system safety architecture, including precharge, e-fuses, contactors, and e-stop systems
- EMI/EMC design and mitigation for switching power systems
- Experience designing for battery hot-swap systems
- Experience managing PCB layout contractors or other external engineering resources
- Experience with DFM, supply chain considerations, test coverage, and production bring-up
- Proficiency in Altium for schematic capture and PCB layout
- Cross-disciplinary experience with firmware, embedded systems, or mechanical design
- Experience managing or mentoring junior engineers
- Robotics experience
Compensation: $180,000-$250,000, depending on experience, skills, and qualifications.
Come Join UsReflex is de-risked enough to see the hazy outlines of success, but still small enough that there's enormous upside for grabs. This is a rare opportunity to help build a flagship robotics company from the ground up and to do work that will truly matter, reshaping what people believe is possible in robotics.
We love to see the things you've worked on. Have a portfolio or a project that people tend to say 'wait, you built that?' when you describe what you worked on? Share it. We're looking for people who push past the status quo, are passionate at work and in their own time, we're looking for people who want to win.
