Job description

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
