Benefits offered by this job

null

Job summary

Dexmate Inc. is seeking an Electrical & Firmware Test Engineer to validate electrical systems, batteries, boards, and motor controllers in real robots. You will build and maintain HIL test rigs and run automated firmware regression tests, ensuring robust performance before deployment.

You will work hands-on at the bench, spend time in the lab, and debug issues directly. The role emphasizes tangible build/test evidence over theory, with strong focus on safety and reliability.

Qualifications

• BS in Electrical Engineering or related field; hands-on validation/work matters more than degree.

Responsibilities

• Define and execute electrical validation plans for power distribution, battery packs and BMS, custom boards, motor drives, sensors, harnesses, and connectors
• Define reliability test flows for PCBAs, harnesses, and connectors, and run them: power cycling, brown-out and fault conditions, high temp/humidity, thermal cycling and shock, connector wear, long-duration burn-in
• Run ESD and EMC pre-compliance testing; support FCC, CE, and UL certification with external labs
• Validate battery safety and performance, and support battery certification (IEC 62133, UN38.3)
• Build and maintain hardware-in-the-loop (HIL) test rigs for motor controllers, joint modules, and main compute boards
• Develop automated firmware regression tests covering communications (CAN, EtherCAT, Ethernet), control loops, safety behaviors, and OTA updates
• Perform fault-injection testing to verify error handling and safe-state behavior
• Lead electrical failure analysis at board and system level, collaborating with engineers to drive fixes
• Write test procedures and maintain test data and reports
