Senior Electrical Engineer — Robotics Power & Drive Systems

Dexmate Inc.; Fremont (CA); On-site; USD 130,000 - 190,000; Full time

Job summary

Dexmate Inc. is seeking a Senior Electrical Engineer to design, develop, and validate core electrical subsystems for our general-purpose robot platforms.

You will own power electronics, motor drive circuits, sensor integration, and PCB design—from schematic through bring-up to production release. This hands-on, high-ownership role requires shaping architecture, driving subsystems end-to-end, and delivering hardware that ships on every unit.

Qualifications

• 5+ years of electrical engineering experience in robotics or related fields.
• Hands-on PCB design experience with multi-layer boards.
• Experience designing power electronics: BMS, power distribution, protection circuits, or DC-DC conversion.
• Motor drive design experience — BLDC, PMSM, or servo drive circuits, ideally with FOC topology.
• Strong bench skills: oscilloscope, current probe, power analyzer, logic/spectrum analyzer.
• Ability to read and interpret electronic circuit diagrams; comfortable integrating sensors and actuators.
• Experience with DFM/DFA and working directly with contract manufacturers.
• Experience designing complex multilayer PCBs (8+ layers), including controlled impedance routing, mixed-signal design, and high-speed differential pairs.

Responsibilities

• Own end-to-end design of power electronics subsystems: battery management, power distribution, protection circuits, and DC-DC conversion.
• Design and validate motor drive circuits for high-performance actuation, including FOC/BLDC/PMSM control topologies.
• Design sensor integration circuits for IMUs, encoders, hall-effect, force/torque, and thermal sensors.
• Create schematics and multi-layer PCB layouts using industry-standard EDA tools, from concept to production release.
• Perform circuit simulation (LTspice) and hardware validation with test equipment.
• Apply EMI/EMC design principles and support certifications as we move toward commercial deployment.
• Drive DFM/DFA decisions to ensure manufacturability and testability at production scale.
• Instrument boards and conduct board-level bring-up, power-on sequencing, and subsystem verification.
• Collaborate daily with firmware engineers on hardware/software interfaces and with mechanical engineers on thermal constraints.
• Document designs with the rigor required for CM handoff and engineering review.
