Hardware Support Engineer

About the role

Dexmate is building AI-powered humanoid robots for industrial and research applications. As a Hardware Support Engineer, you will be a core part of a small, fast-moving hardware team - responsible for hands-on debugging, failure analysis, and maintenance of our robot platform, spanning internal development all the way through to customer support. This role sits at the intersection of hardware and software. You'll be expected to work across both: running root cause failure analysis on a failed actuator or PCBA in the morning, then tracing a communication or network fault on a deployed system in the afternoon. You'll also play a key role in building out our failure analysis processes and capabilities as we scale. You don't need to be a specialist in every area, but you do need a methodical approach to problems, a willingness to learn, and the ability to communicate your findings clearly to both engineering teams and customers. If you are comfortable diving into complex technical issues and turning messy real-world failures into clear, repeatable fixes, this role is a strong fit.

Key facts

What you'll do

• Troubleshoot and identify root causes of hardware and system failures on our robot platform, including power distribution, embedded compute, communication buses, actuators, and sensor subsystems
• Perform end-to-end failure analysis at component (e.g., PCBAs, actuators, connectors), module (e.g., hands, battery packs), and system (robot) levels
• Use bench equipment - oscilloscopes, multimeters, logic analyzers, power supplies, and inspection tools - to characterize signals, isolate failures, and validate fixes
• Read schematics and block diagrams to understand circuit behavior and help identify where things are going wrong
• Collaborate cross-functionally with Mechanical, Electrical, Software/Firmware, and Manufacturing teams to identify and implement corrective actions
• Support bring-up and testing of new hardware revisions: verify power sequencing, communication interfaces, and peripheral behavior
• Debug issues across the robot system, including compute modules, motor controllers, and camera systems
• Act as a technical point of contact for customer-reported issues - reproduce faults, narrow down root causes, and communicate findings clearly to both the engineering team and the customer
• Write and maintain clear repair runbooks, failure analysis reports, and troubleshooting guides that other team members can follow
• Help establish and improve failure analysis processes, best practices, and lab capabilities to minimize time from failure identification to corrective action
• Supervise and drive supplier failure analyses when issues trace back to vendor components
• Work closely with engineers to iterate on hardware during the prototyping phase, helping move designs from early bring-up toward stable, repeatable assemblies

Requirements

• Hold a Bachelor's degree in Electrical Engineering, Mechanical Engineering, Mechatronics, Robotics, Materials Science, or a related technical field - or equivalent hands-on experience
• Bring 2-5 years of experience in hardware failure analysis, field service, test engineering, or hardware debug, preferably in robotics, automotive, automation, or consumer electronics environments
• Demonstrate real-world product development or failure analysis experience in at least two relevant areas such as PCBAs, battery cells/packs, harnesses/connectors, metals, plastics, or actuators/moving parts
• Apply a structured method to hardware debugging and root cause investigation, forming hypotheses and testing them with measurement
• Use bench tools including oscilloscopes, multimeters, power supplies, and logic analyzers to validate electrical behavior and isolate faults
• Interpret schematics and electrical block diagrams to trace current paths, signals, and potential failure points
• Communicate technical findings in writing and verbally to both technical and non-technical stakeholders
• Work effectively in a Linux command-line environment for log inspection, process monitoring, and basic scripting
• Collaborate with cross-functional teams to translate field failures into design changes or manufacturing improvements
• Maintain accurate records of tests, measurements, and conclusions to support traceable decision making

Nice to have

• Experience with NV
