Sustaining Design Engineering Manager

At CelLink, engineering doesn’t stop when a product launches. We’re looking for a Manager, Sustaining Design Engineering who enjoys solving complex technical problems, improving products already in production, and developing a strong team of engineers. You’ll lead design improvements from customer request through CAD updates, validation, and manufacturing implementation. You’ll work closely with customers, Applications Engineering, and Manufacturing to turn real-world challenges into practical, high-quality solutions. This is an opportunity for an engineer who can move comfortably between the technical details and the bigger picture, someone who enjoys mentoring a team but isn’t afraid to roll up their sleeves and own projects themselves. Essential Duties and Responsibilities Manage, mentor, and grow a team of Sustaining Design Engineers, setting clear goals and supporting professional development. Prioritize projects and allocate resources to meet business needs and customer timelines. Build a collaborative, accountable, safety-first culture focused on ownership and continuous improvement. Lead post-launch design changes, product updates, Design for Manufacturability (DFM) studies, and continuous improvement initiatives. Oversee CAD design work, rapid prototyping, validation testing, and design release documentation. Lead design reviews and DFMEA sessions, and participate in PFMEA activities to improve product quality and prevent recurring issues. Develop and refine design rules and guidelines using feedback from Manufacturing Engineering. Ensure engineering changes are accurately documented, validated, and implemented on the manufacturing line in accordance with internal standards, customer expectations, and APQP processes. Serve as a key engineering contact for complex customer-driven changes, technical escalations, and product improvement projects. Partner across Applications Engineering, Manufacturing, and customer teams to troubleshoot issues and deliver effective solutions. Support customer testing and validation activities while maintaining a high standard of communication, responsiveness, and follow-through.
