Job description

The Sustaining Production and Service Electrical Engineer serves as a key technical liaison between Engineering, Manufacturing, Service, Vendors, and Customers, supporting released products throughout their lifecycle. This role focuses on enabling production and service teams through training, documentation, and hands-on technical support, while ensuring clear communication and alignment across internal teams and external partners. The engineer works closely with design engineers, technicians, contract manufacturers, and suppliers to support production, resolve technical issues, and implement continuous product improvements. Responsibilities also include supporting customer inquiries and training, driving corrective actions based on field and production feedback, and ensuring changes are properly documented and released. Travel to manufacturing sites and customer locations of up to 40% may be required.

Technical Expertise

• Acts as a technical bridge between engineering, manufacturing, service, vendors, and customers, ensuring alignment and timely resolution of issues.
• Hands-on troubleshooting of analog, digital, and power electronics systems in production, service, and field environments.
• Supports manufacturing and service teams by diagnosing test failures, yield issues, and field-reported problems.
• Performs failure analysis and root-cause investigation down to the component level using structuredli>
• Implements and tracks corrective and preventive actions, including hardware, process, and documentation improvements.
• Supports Engineering Change Orders (ECOs/ECNs), including schematic updates, BOM changes, and component obsolescence resolution, in collaboration with the engineering team.
• Responds to and manages Engineering Field Requests (EFRs) originating from service teams and customers.
