Manufacturing Engineer, CNC Machinist
Job Description & How to Apply Below
We build complex, precision components — and we do it right. That means the people running our machines aren't button-pushers. They're skilled machinists who take ownership of their work, hold themselves to a high standard, and care about what comes off the floor.
We're looking for an experienced CNC Machinist who is ready to contribute across our full platform — vertical mills, 5-axis mills, turning centers, and mill-turn machines. You'll execute setups and production with real ownership, maintain consistent quality, and play an active role in a shop where precision isn't optional.
What You'll Do
Setup and Machine Operation
You'll set up, run, and break down CNC machining jobs across multiple platforms — loading fixturing, establishing datums, setting work offsets, building and qualifying tooling, and verifying readiness through first-piece validation before production begins. You'll operate using pre-proven programs on well-documented work and take increasing ownership of more complex setups as your experience and confidence grow.
In-Process Quality and Inspection
You'll monitor machine performance, tool wear, and part quality throughout production using hand metrology — calipers, micrometers, height gauges, and related instruments. You'll identify out-of-tolerance conditions, work through them with a structured mindset, and escalate when needed to keep quality intact. Troubleshooting and Process Improvement
You'll work through issues related to tooling, work holding, machine performance, and material behavior — collecting data, collaborating with senior team members, and contributing your own observations to drive resolution. Over time, you'll apply a deeper understanding of machining principles to recommend improvements in tooling, fixturing, and workflow efficiency.
Documentation and ERP
You'll accurately complete all required production documentation and time tracking in Pro Shop ERP — including job time, status updates, and production notes — ensuring traceability and supporting downstream planning and quality functions.
Training and Team Contribution
You'll engage in structured training to build understanding of not just execution steps but the reasoning behind tooling, fixturing, and sequencing decisions. You'll share what you learn, reinforce best practices with teammates, and contribute to a culture where everyone is getting better.
Shop Standards
You'll deburr and clean components, maintain an organized workspace, uphold 5S standards, perform routine machine maintenance, and report equipment issues promptly. Safety protocols — including AS9100, ISO
9001, and ITAR practices — are followed without exception.
What We’re Looking For
Experience and Education
High School Diploma with at least 4 years of relevant CNC machine operation experience; or
Associate's degree in manufacturing, Machining Technology, or a related discipline with at least 2 years of relevant CNC machine operation experience.
Relevant experience includes hands-on setup and operation of CNC mills, lathes, or mill-turn equipment; ability to read technical setup documentation; and use of hand metrology instruments.
Familiarity with Haas, Okuma, and/or Heidenhain controls preferred.
Experience with Pro Shop ERP or a comparable production management system is a plus.
Skills and Abilities
Solid setup capability across CNC platforms with working knowledge of tooling, work holding, and offsets.
Ability to read and interpret setup sheets, work instructions, prints, and GD&T callouts.
Strong attention to detail and process discipline; committed to consistent, accurate execution.
Effective troubleshooting skills with an ability to identify root causes and contribute to permanent solutions.
Clear communicator who asks good questions, keeps stakeholders informed, and collaborates well with engineers, programmers, and teammates.
Positive, team-oriented mindset with a focus on reliability, continuous learning, and helping others develop.
Who You Are
You've got real time behind CNC machines. You know your way around a setup — tooling, fixturing, offsets, first-piece validation — and you take it seriously. You understand that what…
