Senior Electrical Engineer

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.

Job description

Dexmate is building the foundation for physical AI — combining a new generation of robots with a universal Physical AI OS, making robots as easy to build and deploy as software. Today, robotics is fragmented, slow, and closed: most builders are forced to reinvent the same stack again and again, and most ideas never make it past the prototype stage. We exist to change that. Our mission is to democratize robotics by lowering the barrier to entry, delivering a plug-and-play platform for developers, researchers, and enterprises, and cultivating an open ecosystem that accelerates the evolution of physical AI. If you want to help shape the next layer of human capability — and believe the future of robotics should be built together, not in isolation — we’d love to build it with you.

The Role

We are looking for a Senior Electrical Engineer to design, develop, and validate the core electrical subsystems of 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-ready hardware.

This is a hands-on, high-ownership role. You will make architecture decisions, drive subsystems end-to-end, and be accountable for hardware that ships on every unit.

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 sensors, force/torque sensors, and thermal sensors

• Create schematics and multi-layer PCB layouts using industry-standard EDA tools (e.g., Altium, Cadence Allegro, KiCad), owning the full cycle from concept through layout review, prototype bring-up, and production release

• Perform circuit simulation (LTspice or equivalent) and systematic hardware validation using oscilloscopes, current probes, power analyzer, and spectrum analyzers

• Apply EMI/EMC design principles from the start; support FCC, CE, and UL certification as we move toward commercial deployment

• Drive DFM/DFA decisions to ensure designs are manufacturable and testable 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 physical integration and thermal constraints

• Document designs with the rigor required for CM handoff and engineering review

Minimum Qualifications

• 5+ years of electrical engineering experience in robotics, industrial automation, automotive, or consumer electronics — with at least one product shipped to production

• Hands-on PCB design experience in industry-standard EDA tools (Altium, Cadence Allegro, KiCad, or equivalent) for complex, multi-layer boards with high-speed digital, power, and mixed-signal on the same design

• Proven 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, signal integrity debug

• 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

Preferred Qualifications

• Experience taking a product through FCC, CE, or UL certification, including EMC pre-compliance testing

• Functional safety design experience (ISO 26262, IEC 61508, or equivalent)

• Familiarity with embedded firmware at the hardware/firmware boundary — enough to co-debug with firmware engineers without needing translation

• Experience with high-density or thermally-constrained PCB layouts

• Background in production test fixture design and manufacturing ramp

• Proficiency in Python or similar scripting for test automation

• Hands-on use of AI-assisted EDA or coding tools in your design workflow
