Russ Van Zile, Production Manager About the Job We’re seeking a Mechanical Supervisor who will lead from the front—operating CNC machines daily while building the mechanical function’s foundation for future growth. This working supervisor role is ideal for someone who thrives in a dynamic manufacturing environment, has strong instincts around fabrication and workflow efficiency, and knows how to build clarity and momentum within a small, cross-trained team. Who You Are You’re a hands-on leader with deep roots in CNC machining and mechanical production.

You understand how to balance doing the work with improving how the work gets done. You take initiative, keep things organized, and communicate clearly—especially under pressure. You’re ready to step into a leadership role on day one and take full ownership of the mechanical function in a high-mix, low-volume environment.
