We're looking for a driven, hands-on Manufacturing Engineer to join our high-spec aerospace and defense manufacturing operation. We don't run a "plug-and-play" shop. We build large, complex CNC machined components and fabricated assemblies that go into mission-critical aerospace, defense, and energy systems-where precision and execution matter. This role is intentionally open-ended. You will sit at the center of production, owning how work actually gets done-from process development and machining strategy to real-time problem solving on the shop floor. This is not a support role. This is a build-it, improve-it, own-it role. If you see inefficiencies, you fix them. If you see better ways to run parts, you implement them. If something breaks in production, you step in and solve it. For the right person, this is an opportunity to gain full visibility into manufacturing operations and grow quickly into senior engineering or operational leadership. Compensation $70,000...
