Robotics Electrical & Firmware Validation Engineer

Linuxconfig; Fremont, Northern (CA, KY); Hybrid; USD 120,000 - 170,000; Full time

Job summary

Dexmate seeks an Electrical & Firmware Test Engineer to validate power systems, batteries, boards, harnesses, and motor controllers in real robots. You will build and maintain HIL rigs and run tests to catch issues before customers see them.

This hands-on role focuses on bench and lab work, with emphasis on practical debugging. You should have a strong hardware test background, be proficient in Python for automation, and comfortable working with CAN, EtherCAT, and Ethernet.

Qualifications

• BS in Electrical Engineering, Computer Engineering, or a related field, or equivalent hands-on experience — proven test and debug work matters more to us than the degree
• 4+ years of hands-on experience in electrical validation, hardware test, or embedded test for robotics, automotive, industrial, or consumer electronics
• Strong bench skills: oscilloscopes, current probes, power analyzers, electronic loads, thermal cameras
• Ability to read schematics and debug at board level
• Experience testing power electronics, battery systems, or motor drives
• Proficiency in Python for test automation and comfort working in Linux
• Familiarity with embedded systems and communication buses (CAN, SPI, I2C, UART, Ethernet)

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 temperature/high humidity, thermal cycling and shock, connector and harness wear, and 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, working with electrical and firmware engineers to drive fixes
• Write test procedures and maintain test data and reports
