About This Role

We're standing up a new manufacturing facility and need a Machine Shop Manager to own the floor. You'll run day-to-day machining, fabrication, and CNC production, translating the production schedule into completed parts while directly managing machinists, machine operators, fabricators, and CNC programmers. This is a hands-on leadership role—you'll drive machine utilization, on-time completion, and scrap reduction, and in the rare moment the team needs it, you're not above jumping on a machine yourself to keep parts moving. If you want to run a shop floor instead of just watching a dashboard, this is that role.

Responsibilities

• Manage daily machine shop operations across machining, fabrication, and CNC production, translating the production schedule into completed parts.
• Directly oversee Machinists, Machine Operators, Fabricators, and CNC Programmers.
• Drive machine utilization/OEE, on-time schedule completion, and scrap and rework reduction.
• Partner with Automation & Controls on changeovers and with Quality on inspection handoffs.
• Hold machine utilization, quality, and safety standards on the shop floor.
• Be willing to jump on a machine yourself in the rare instance the team needs an extra set of hands to keep production moving.

Basic Qualifications

• Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc).
• Strong understanding of engineering fundamentals.
• Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information.
• High school diploma or equivalent required; technical degree or trade certification in machining/manufacturing a plus.
• 7+ years in a CNC machine shop environment, including direct supervision of machinists, operators, and fabricators.

Preferred Skills and Experience

• Experience in a fast-paced engineering or highly technical environment, with a resourceful approach to delivering under tight timelines or budget constraints.
• Hands-on CNC machining or fabrication experience—able to run a mill or lathe, not just manage from the office.
• Experience with MES, ERP, or CMMS systems for job routing, production tracking, and machine maintenance.
• Direct experience standing up or scaling a new or growing machine shop.
• Working knowledge of OEE, changeover reduction, and shop floor scheduling practices.
• Experience in a regulated manufacturing environment (aerospace, defense, or nuclear) is a plus.

Additional Requirements

• Ability to work extended hours and weekends as necessary.
