Position Summary Nuvotronics is seeking a highly motivated Sustaining Engineer to serve as the technical bridge between Engineering, Purchasing, Strategic Sourcing, Manufacturing, Quality, and Program Management. This role is responsible for ensuring that released products can be manufactured efficiently, sourced reliably, and sustained throughout the product lifecycle. The Sustaining Engineer will drive the technical resolution of component, material, supplier, and manufacturing issues while supporting cost reduction, lead‑time improvement, supplier qualification, and engineering change implementation.

The ideal candidate combines strong engineering fundamentals with an understanding of procurement, supplier management, manufacturing processes, and cross‑functional project execution.

Serve as the primary technical point of contact between Engineering and Purchasing/Strategic Sourcing. Review new and existing designs to identify sourcing risks, obsolescence concerns, manufacturability challenges, and sole‑source dependencies. Provide technical guidance during supplier selection, qualification, and risk assessments. Support procurement in evaluating alternate components, raw materials, processes, and suppliers.

Own sustaining engineering activities for released products and established manufacturing processes. Investigate and resolve production issues, component shortages, supplier quality concerns, and field‑return issues. Drive root‑cause analysis and corrective and preventive actions associated with supplier and manufacturing issues. Support product transfers, process improvements, yield enhancement, and capacity expansion initiatives.

Lead engineering change activities associated with materials, suppliers, processes, and product improvements. Evaluate the technical, quality, schedule, and cost impacts of proposed changes. Collaborate with Program Management, Manufacturing, Quality, and Supply Chain to ensure timely and effective implementation of ECNs/ECOs. Maintain accurate technical documentation, specifications, drawings, bills of material, and change records.

Partner with Purchasing to develop mitigation strategies for high‑risk, long‑lead, custom, and single‑source materials. Support supplier audits, technical reviews, capability assessments, and qualification efforts. Review supplier technical documentation, specifications, process controls, and manufacturing capabilities. Drive alternate‑source qualification to improve supply chain resiliency and continuity.

Identify cost‑reduction opportunities through design optimization, supplier development, material substitution, and component standardization. Support value engineering initiatives and make‑versus‑buy analyses. Partner with sourcing teams to evaluate technical tradeoffs associated with supplier, material, or process changes. Analyze yield, scrap, supplier performance, quality trends, and manufacturing…
