## Job description

## About Dexmate

Dexmate is building robot platforms and a universal Physical AI OS to make robots easier to build and deploy. We combine hardware and software into a plug-and-play platform for developers, researchers and enterprises, with an open ecosystem that supports the development of physical AI.

## The Role

We are looking for a Motor Electromagnetic Design Engineer to develop PMSM and BLDC motors for integrated robot actuators. You will own the electromagnetic design from topology and sizing through prototype characterization, working with mechanical, thermal and drive engineers to deliver performance within the actuator’s real packaging, voltage, current and duty-cycle limits.

## Responsibilities

- Evaluate motor topologies and size active materials for required torque-speed performance, efficiency and mass, including frameless or outrunner configurations where appropriate.
- Design slot and pole combinations, winding layouts, magnets, laminations and air gaps; evaluate saturation, losses, cogging torque and torque ripple.
- Build electromagnetic FEA models and analytical checks; document assumptions, material properties and sensitivity to manufacturing tolerances.
- Co-design the motor with thermal and mechanical engineers, accounting for heat paths, retention, clearances, assembly and manufacturability.
- Work with drive and firmware engineers on motor parameters, bus voltage, current limits, back-EMF and operating envelopes before design release.
- Support suppliers and prototype builds; characterize motors on the bench or dynamometer and correlate measured constants, torque, efficiency and temperature to predictions.

## Minimum Qualifications

- Hands-on electromagnetic design experience with PMSM or BLDC motors, including a design that was built and experimentally characterized.
- Strong understanding of winding design, magnetic circuits, materials, loss mechanisms and torque production.
- Proficiency in an electromagnetic design or FEA tool such as Motor-CAD, JMAG, Ansys Maxwell, Flux or an equivalent workflow.
- Ability to connect simulation to test data and work directly with mechanical, thermal, inverter and manufacturing engineers.

## Preferred Qualifications

- Experience with frameless, outrunner, high torque-density or low-cogging motors for robotics, servos, drones or EV traction.
- Experience optimizing winding manufacture, magnet retention, lamination production or motor assembly with suppliers.
- Python or MATLAB for design sweeps, data analysis and model correlation.

## About Dexmate

## Company Overview
- **One-liner**: Dexmate builds general-purpose robots with manipulation capabilities, integrating custom hardware with AI models for robotic operation.
- **Entity Type**: Private (Seed Stage)
- **Headquarters**: Santa Clara, California, United States

## Core Business
- Primary industry/industries: Robotics Engineering, Artificial Intelligence, Automation
- Target customers: B2B (enterprise, logistics, manufacturing, and research organizations)
- Mission or purpose statement: "Building tomorrow's intelligence and automation."

## Products & Services
- **[Vega]**: A general-purpose mobile robot with high-payload arms, dexterous hands, a foldable torso, and an omnidirectional base. The robot is powered by custom-built hardware integrated with AI models for physical robotic operation.

## Market Standing
- **Valuation/Market Cap**: Not publicly available
- **Key Metric**: Total Funding raised via a Seed Round (closed ~March 2026) with participation from LG Technology Ventures as a lead investor.
- **Notable Investors/Partners**: LG Technology Ventures (lead investor), LG CNS (strategic partner for building Physical AI infrastructure for smart logistics).
- **Growth Signals**: Headcount grew +328.6% year-over-year (from ~4 to 18 employees). LinkedIn followers grew +67.8% yearly. In April 2026, launched the "Dexmate Build with Vega U Research Grant Program," selecting six research teams to receive a Vega robot. Strong hiring momentum with 11 active job postings as of mid-2026.

## Competitive Advantages
- **Integrated Hardware + AI Stack**: Designs custom high-payload arms, dexterous hands, and omnidirectional bases specifically for AI-driven manipulation, creating a tight hardware-software moat.
- **Physical AI Focus**: Differentiating by building "Physical AI" that moves beyond lab settings into real-world logistics and manufacturing, as evidenced by the partnership with LG CNS.
- **Rapid Scaling**: Demonstrated ability to grow headcount and attract top-tier talent from institutions like Carnegie Mellon University, UC San Diego, and companies like NVIDIA and Bosch.

## Strategic Focus
- **Physical AI Infrastructure**: Partnering with LG CNS to build the infrastructure that enables Physical AI to operate in smart logistics and manufacturing environments.
- **Research & Ecosystem**: Grant programs to seed the research community with Vega robots, driving platform adoption and innovation.
- **Talent Acquisition**: Aggressively hiring across engineering (AI, robotics, embedded systems), design, product management, and business development to scale the team.

## Why Work Here
- **Mission-Driven**: Opportunity to work on cutting-edge general-purpose robotics and Physical AI, moving technology from labs to real-world impact.
- **Engineering-Heavy Culture**: 60% of employees are in technical roles (AI, robotics, software, hardware), with a strong emphasis on hands-on building.
- **Fast-Growing Startup**: ~328% headcount growth in one year, indicating high trajectory and opportunity for early employees to have outsized impact.
- **Location**: HQ in Santa Clara, CA (Silicon Valley), with an in-office work policy (on-site workspace).
- **Compensation**: Engineering roles list salary ranges like $100K–$300K, competitive for the robotics/AI space.
- **Notable Culture Signals**: "Build with us" hiring language, active LinkedIn community (4,273 followers), and a focus on "smile, reach out, and instantly connect" suggests a collaborative, builder-oriented environment.
