• Collaborate closely with Firmware, Mechanical, Manufacturing, and QA teams to ensure seamless product integration and reliable system performance.
• Participate in prototype development stages including EVT, DVT, and support production readiness activities.
• Conduct Design for Manufacturing (DFM) and Design for Testability (DFT) reviews with manufacturing partners.
• Prepare and maintain technical documentation including schematic files, PCB files, Gerber, BoM, wiring diagrams, assembly guides, and validation reports.
• Manage Bill of Materials (BoM), component sourcing, alternative part validation, and lifecycle risk mitigation for EOL or shortage components.
• Perform root-cause analysis on hardware failures, field returns, and production issues, then implement corrective design improvements.
• Support environmental and reliability testing including thermal, vibration, power transient, and pre-compliance EMC testing.
• Assist manufacturing and production teams during pilot builds and mass production troubleshooting.
