Job Summary

We are looking for a technically strong and detail-oriented Hardware Diagnostics Specialist to support and analyze field returns, defective units, and customer-reported issues. The ideal candidate will work closely with customer support, quality, and engineering teams to carry out root cause analysis (RCA), component-level debugging, and design feedback for improving EV charger hardware.

Key Responsibilities

● Diagnostics & Root Cause Analysis (RCA): Conduct detailed hardware diagnostics of returned or failed EV chargers. Identify root causes for failures across components, boards, and system-level performance.

● Failure Replication & Testing: Recreate customer-reported issues using lab equipment. Validate hardware functionality under simulated conditions and power cycles.

● Component-Level Debugging: Use oscilloscopes, multimeters, power supplies, and diagnostic tools to debug PCBs, power modules, and embedded controllers.

● Documentation: Log all findings in structured diagnostic reports. Maintain a failure database to track trends and common issues.

● Cross-Functional Coordination: Collaborate with hardware design, firmware, and product teams to share diagnostic insights and suggest design or manufacturing improvements.

● Corrective Action Support: Support implementation of CAPA processes, and provide feedback to quality and production teams for process improvements.

● Customer Feedback Loop: Translate technical root cause findings into actionable feedback for customer-facing teams to communicate resolutions effectively.

Requirements

● Bachelor’s degree in Electrical/Electronics Engineering or similar field.

● 2+ years of hands-on experience in hardware testing, debugging, or repair—preferably in EV, power electronics, or IoT industries.

● Strong experience with lab tools like oscilloscopes, power analyzers, and test jigs.

● Ability to analyze PCB schematics, interpret firmware logs, and perform board rework/soldering.

● Familiarity with communication protocols such as CAN, RS485, and Ethernet.

● Understanding of high-voltage safety practices.

● Good documentation and communication skills.

● Willingness to work in lab/field environments as required.

Preferred Qualifications

● Experience with EV chargers, AC/DC conversion, or onboard diagnostic systems.

● Exposure to debugging embedded systems and reading UART logs or diagnostic traces.

● Knowledge of quality systems and tools like 5 Whys, FMEA, or 8D problem solving.

● Familiarity with version control (e.g., Git), Postman, or basic firmware flashing tools.
