Test Systems Engineer

Dexmate Inc.; United States; On-site; USD 85,000 - 115,000; Full time

Job summary

Dexmate Inc. is seeking a Test Systems Engineer to design and maintain automated test stations for our robotics lab. You will build rigs, data logging, and dashboards so durability tests run around the clock and reflect real customer use.

You will collaborate with mechanical, electrical, and software teams, qualify test stations for accuracy, and support test engineers while ensuring safety and reliability across dozens of modules.

Qualifications

• BS in Mechatronics, Mechanical, Electrical, or Robotics Engineering.
• 3+ years building test equipment, automation, or robotic systems.
• Proficiency in Python for automation and data handling; Linux CLI comfortable.
• Hands-on experience with sensors, motors, and DAQ/PLC systems.
• Familiar with mechanical assembly and safety considerations.

Responsibilities

• Design, build, and maintain automated test stations and rigs combining mechanical fixtures, motors, sensors, PLCs or microcontrollers, and software
• Build data acquisition and logging systems, and dashboards that track test status and results across all test stations
• Automate long-duration durability and duty-cycle tests to run unattended overnight and on weekends, with alerts and automatic shutdown on failure — scaling to dozens of modules on test in parallel
• Qualify every test station for accuracy, repeatability, and stability before its data is trusted
• Design simple interface boards and harnesses for test setups, and work with equipment suppliers on custom stations
• Run whole-robot functional tests: mobility, manipulation, payload, terrain, and continuous operation
• Develop and run working-condition tests based on real customer scenarios and environments
• Assemble, configure, and prepare robots and subsystems for testing
• Keep the lab running: equipment setup and calibration, spare parts and inventory, and lab safety (battery handling, robot motion safety zones)
• Support mechanical and electrical test engineers in executing their test plans

Job description

About Dexmate

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 Test Systems Engineers to build the machines that test our robots and to keep our new test lab running. You will design automated test rigs, data logging, and dashboards so durability tests can run around the clock, and you will run whole-robot functional and working-condition tests that reflect how customers actually use our robots. You are the force multiplier: the more you automate, the more the team can test.

Responsibilities

• Design, build, and maintain automated test stations and rigs combining mechanical fixtures, motors, sensors, PLCs or microcontrollers, and software

• Build data acquisition and logging systems, and dashboards that track test status and results across all test stations

• Automate long-duration durability and duty-cycle tests to run unattended overnight and on weekends, with alerts and automatic shutdown on failure — scaling to dozens of modules on test in parallel

• Support mechanical and electrical test engineers in executing their test plans

Minimum Qualifications

• BS in Mechatronics, Mechanical, Electrical, or Robotics Engineering, or equivalent hands-on experience

• 3+ years building test equipment, automation, or robotic systems

• Proficiency in Python for automation and data handling, and comfort with Linux command line

• Hands-on experience with sensors, motors, and DAQ or PLC systems

• Comfortable with mechanical assembly, wiring, and basic fabrication

• Strong troubleshooting skills across mechanical, electrical, and software

Preferred Qualifications

• Experience with ROS/ROS 2 or robot middleware

• Experience building test dashboards and databases

• Background in robotics competitions, makerspaces, or building robots end-to-end

• Experience running a hardware lab, including equipment calibration and safety programs
