Senior Manufacturing Engineer – CNC Machining

WHAT YOU'LL DO

• Develop CNC programs and machining strategies for complex components

• Take pride in building processes that run right the first time
• Know how to balance quality, efficiency, and production demands
• Lead by example and enjoy sharing your knowledge
• Stay calm under pressure and find practical solutions

• Your experience is respected and your ideas are heard
• Work alongside people who care about craftsmanship and quality
• Join a company investing in technology, people, and long-term growth

• Deep understanding of tooling, fixturing, and machining strategy
• Ability to read engineering drawings and GD&T
• Experience taking new parts from prototype into production
