About the Opportunity
We build complex, precision components - and we do it right. That means the people who program our machines aren't order-takers. They're problem-solvers, process owners, and technical contributors who take real pride in what comes off the floor.
The CNC Programmer II is for someone who has put in the reps and is ready to work with genuine independence. You've developed solid foundations in 2-axis turning and/or 3-axis milling, you know how to build a setup from scratch, have a strong understanding of fixturing and tooling, and you can take a program from toolpath to production handoff without someone looking over your shoulder.
At this level, you're not just executing - you're contributing. You'll take end-to-end ownership of programs and setups, lead your own prove-outs, and produce documentation that operators can actually use. You'll begin expanding into 3+2 and introductory 5-axis work, and you'll play an active role in building team capability - sharing knowledge with Programmer I colleagues and training machine operators not just on the steps, but on the reasoning behind them.
This is a role for someone who shows up ready to deliver, holds themselves to a high standard, and wants to grow into more.
What You'll Do
Programming and Process OwnershipWhat We're Looking For
Experience and Education
High School Diploma with at least 6 years of relevant CNC programming experience; or Associate's degree in manufacturing, Machining Technology, CNC Programming, or a related field with at least 4 years of relevant experience. Demonstrated proficiency programming 2-axis turning and 3-axis milling in Hypermill, Esprit, or a comparable CAM platform, including machine prove-outs and setup documentation. Hands-on experience with Haas, Okuma, and/or Heidenhain CNC controllers preferred. Experience with ProShop ERP or a comparable production management system is a plus.Skills and Abilities
Proven ability to develop complete, production-ready CNC programs for 2-axis turning and 3-axis milling independently. Solid understanding of tooling selection, cutting strategy development, and work-holding across a variety of component geometries. Ability to read and interpret engineering drawings and GD&T callouts and apply them to programming and inspection decisions. Demonstrated experience identifying and resolving programming and quality issues through structured root-cause thinking and permanent corrective action. Ability to coach Programmer I colleagues and train machine operators through direct instruction and clear process communication. Strong documentation and communication skills; adaptable to operators, engineers, and supervisors alike. Track record of sound judgment and consistent, reliable delivery. Committed to continuous technical growth - actively pursues expanded programming capability.Who You Are
You are a technically confident CNC programmer who has moved beyond following instructions and now trusts your own judgment. You've proven you can take a component from drawing to production-ready program - and you take real pride in getting it right the first time. You're self-directed and dependable. When you commit to a timeline, you meet it. When something isn't working, you dig in, figure out why, and fix it for good - not just for today's job, but for the next one. You communicate clearly and adjust naturally to your audience, whether you're explaining a process to a machine operator, walking an engineer through a toolpath decision, or flagging an issue to a supervisor. You don't wait to be asked - you keep people informed. You're a natural teacher. You genuinely enjoy helping others understand not just what to do, but why - and you find satisfaction in watching a colleague or operator handle something confidently that they couldn't before. You're not finished learning. You actively seek out opportunities to expand your technical repertoire - new CAM techniques, tooling strategies, machining principles - because you see the craft of programming as something worth pursuing at a high level. And you care about the details. Your documentation is thorough, your setups are clean, and you hold yourself to a standard that the whole team can count on.Physical Requirements
The physical demands described below are representative of those that must be met by an employee to successfully perform the essential functions of this role.

Wear required PPE at all times on the shop floor, including safety glasses, hearing protection, and steel-toed footwear. Use precision metrology instruments including calipers, micrometers, and indicators. Hold a valid driver's license for occasional logistics tasks.Overtime may be available and is occasionally required. Some non-standard hours, including early mornings or evenings on weekdays and weekends, may be needed.

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 OperationWhat 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 ProShop ERP or a comparable production management system is a plus.Skills and Abilities
Solid setup capability across CNC platforms with working knowledge of tooling, workholding, 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 happens at the machine determines whether the part is good, and you hold yourself accountable for that. You pay attention. You notice when something is off - a tool that's wearing, a dimension that's drifting, a process that doesn't quite make sense - and you do something about it rather than let it go. You communicate. When you're unclear, you ask. When something is at risk, you say so. When a supervisor or engineer needs to know, you make sure they do. You're invested in getting better. You want to understand not just the steps, but the reasoning behind them - so that when conditions vary, you know how to respond. And you show up for the team. You share what you know, help others improve, and contribute to a shop that runs well.Physical Requirements

What You'll Do
Inspections
Conduct thorough manual inspections at receiving (to catch supplier issues early), in-process (to identify problems before final machining), and final stages (as the last quality gate before customer delivery). Perform dimensional inspections using precision metrology tools including calipers, micrometers, height gauges, thread gauges, and bore gauges to verify critical dimensions and tolerances. Identify and document visual defects including nicks, scratches, burrs, surface finish inconsistencies, coating defects, and contamination. Operate CMM (Zeiss/Calypso) to run pre-programmed inspections: load and unload parts, verify proper setup, and interpret results against engineering requirements Read and interpret technical drawings and GD&T to verify critical dimensions, tolerances, and geometric characteristics ensuring parts meet specifications.Documentation & Compliance
Maintain accurate inspection records for all visual and dimensional findings in ProShop MES in compliance with AS9100 and ISO 9001 quality standards. Communicate any deviations, non-conformances, or visual defects clearly and promptly with supporting photos or documentation.
