Sr Cnc Programmer information

What is a Sr CNC programmer?

Sr CNC Programmers, or Senior Computer Numerical Control Programmers, are experienced professionals responsible for creating, testing, and optimizing programs that control CNC machines used in manufacturing. They interpret blueprints and technical drawings to develop instructions that guide machines in producing precision parts and components. In addition to programming, they often troubleshoot issues, select appropriate tools, and collaborate with engineers and machinists to ensure efficient and accurate production. Their expertise is crucial for maintaining high-quality standards and improving manufacturing processes.

What are some common challenges Sr CNC programmers face when transitioning to a new manufacturing environment?

When starting at a new facility, Sr CNC Programmers often encounter challenges such as adapting to different CNC machines, varying software platforms, and unique production workflows. Each shop may have its own set of standards, tooling preferences, and quality control procedures, which require quick learning and flexibility. Building rapport with machinists and collaborating with engineering or design teams is essential for ensuring smooth program implementation and minimizing production errors. Embracing these challenges can lead to faster acclimation and improved process optimization.

What are the key skills and qualifications needed to thrive as a Sr CNC programmer, and why are they important?

To thrive as a Sr CNC Programmer, you need advanced knowledge of CNC machining, precision measurement, and a strong background in mechanical or manufacturing engineering, often supported by relevant technical certifications or diplomas. Expertise in CAD/CAM software (such as Mastercam, SolidWorks, or AutoCAD), G-code programming, and familiarity with CNC machine operation are typically required. Strong problem-solving abilities, attention to detail, and effective communication skills set top professionals apart. These skills ensure the efficient production of high-quality components, minimize errors, and support seamless collaboration in manufacturing environments.

What is the difference between Sr Cnc Programmer vs Cnc Programmer?

AspectSr Cnc ProgrammerCnc Programmer
CredentialsTypically requires more experience, advanced certifications, or specialized trainingEntry to mid-level certifications and experience
Work EnvironmentManufacturing shops, aerospace, automotive, and precision machining facilitiesSimilar environments, often in smaller or less complex operations
ResponsibilitiesDesigns complex CNC programs, mentors junior staff, optimizes machining processesCreates CNC programs based on blueprints, sets up machines, and runs production

The main difference between a Sr Cnc Programmer and a Cnc Programmer lies in experience, complexity of tasks, and leadership responsibilities. A Sr Cnc Programmer typically handles more advanced programming, process optimization, and mentorship, whereas a Cnc Programmer focuses on creating and executing CNC programs for production. Both roles are essential in manufacturing, but the senior position requires greater expertise and often more certifications.

Why This Role Exists

This role exists because Freeform is scaling production.

Freeform is actively delivering production-scale metal parts for aerospace, defense, automation, and industrial customers. As production volume and part complexity increase, this role is critical to ensuring precision, throughput, and repeatability in post-print CNC machining.

As a Senior CNC Programmer, you’ll play a key role in bridging metal additive manufacturing and high-precision 5-axis CNC machining, helping define how next-generation manufacturing actually works on the shop floor.

---

The Work You’ll Be Doing

In this role, you will:

  • Program, set up, and run 5-axis DMG Mori CNC mills
  • Post-machine complex metal 3D printed parts to tight tolerances
  • Optimize toolpaths, speeds, feeds, and strategies for efficiency and part quality
  • Machine parts directly from blueprints and 3D CAD models
  • Hold tight tolerances (±0.001” and tighter depending on part)
  • Perform deburring, cleaning, and finishing operations
  • Inspect parts using micrometers, thread gauges, indicators, and probing
  • Support preventative maintenance and cutting fluid management
  • Collaborate closely with engineers to improve programs, fixtures, and automation
  • Contribute to process improvement initiatives focused on throughput and repeatability

This is a hands-on programming role, not a desk-only CAM position.

---

Machines, Controls & Software

You’ll work with equipment such as:

Machines:

  • DMG Mori 5-Axis CNC Machining Centers

Controls:

  • Siemens

CAM Software:

  • Mastercam (highly preferred)

Inspection Tools:

  • On-machine probing
  • Micrometers, indicators, thread gauges, precision hand tools

---

What We’re Looking For

Required:

  • 5+ years of 5-axis CNC mill programming experience
  • Strong experience with DMG Mori 5-axis machines
  • Proven ability machining aluminum, stainless steel, titanium, or Inconel
  • Deep understanding of setups, tooling, speeds/feeds, and optimization
  • Ability to read blueprints, GD&T, and CAD models

Preferred (Not Required):

  • Mastercam programming experience
  • Siemens control experience
  • Experience machining metal 3D printed parts
  • NTMA certification or equivalent formal training
  • Experience with automation, fixtures, or multi-axis optimization
  • Comfortable operating cranes, forklifts, and shop equipment

---

Materials You’ll Work With

  • Aluminum
  • Stainless Steel
  • Titanium
  • Inconel & nickel-based alloys

---

Why Machinists Like Working at Freeform

Machinists choose Freeform because:

  • Modern 5-axis CNC equipment and cutting-edge technology
  • Real collaboration between machinists, programmers, and engineers
  • High-skill work — not button pushing
  • Stable, production-focused workflows
  • Competitive hourly pay plus meaningful equity ownership
  • A clean, organized, state-of-the-art facility
  • Opportunities to influence how manufacturing scales globally

This is a place for machinists who want to build something new, not just run jobs.

---

Pay, Benefits & Schedule

Pay: $45 – $65/hour (DOE)
Top of range reserved for exceptional technical depth and experience

Benefits Include:

  • Significant pre-IPO stock option packages
  • 100% employer-paid Medical, Dental & Vision insurance
  • Traditional & Roth 401(k)
  • Relocation assistance
  • Paid vacation, sick leave, and holidays
