The ideal candidate has hands-on experience in setup, operation, and basic programming of CNC lathes and mills, and is comfortable working from technical drawings and CAD/CAM files to produce tight-tolerance parts in steel, aluminum, and specialty alloys.

This position plays a key role in producing parts that meet ISO 9001 and CMMC quality standards for MCS’s Critical Equipment product line, including TL-4 rated road barrier systems, mobile power platforms, and precision-fabricated assemblies.

Key Responsibilities: 

• Set up and operate CNC mills, lathes, and manual machines to produce precision parts
  per engineering drawings and specifications.


• Read and interpret blueprints, GD&T drawings, and process sheets to determine machining requirements.


• Create, edit, and optimize CNC programs using G-code and/or CAM software.


• Verify part dimensions using precision measuring instruments (micrometers, calipers, height gauges).


• Perform tool setup, offsets, and fixture alignment to ensure part accuracy and repeatability.


• Maintain machine cleanliness, lubrication, and safety standards.


• Collaborate with engineering and fabrication teams to resolve design or manufacturability challenges.


• Contribute to continuous improvement efforts in productivity, quality, and safety.


• Document production runs and inspection results in accordance with internal quality procedures.

Desired Technical Experience: 

• CNC Programming:
  
  
  
  • Proficiency with G-code, Fanuc, Haas, or Siemens controls.
  
  
  • Experience using CREO or GIBBSCAM for toolpath creation preferred.
  
  
  • Ability to make on-machine program edits and optimizations.
  
  
  
  


• Machining Processes:
  
  
  
  • 3- and 4-axis milling, turning, drilling, and tapping of steels, aluminum, and specialty materials.
  
  
  • Understanding of feeds, speeds, and tooling selection.
  
  
  • Have some experience with manual mills and lathes.
  
  
  
  


• CAD/CAM Integration:
  
  
  
  • Experience reading and working from 3D CAD models (STEP/IGES/SolidWorks).
  
  
  • Ability to provide feedback to engineering on model-to-part transition issues.
  
  
  
  


• Quality & Inspection:
  
  
  
  • Familiarity with ISO 9001 documentation and quality control practices.
  
  
  • Use of CMM or optical inspection systems is a plus.
    
  
  
  
  

Qualifications: 

• 2+ years of CNC machining or equivalent technical experience.


• Trade school diploma or associate degree in Machining Technology, Manufacturing Engineering, or related field preferred.


• Demonstrated ability to read and interpret complex engineering drawings.


• Strong mechanical aptitude and attention to detail.


• Ability to work independently and as part of a cross-functional team.


• Must meet eligibility requirements for work on defense-related contracts (U.S. citizenship required).
  

Compensation & Benefits: 

• Competitive hourly wage based on experience.


• Overtime opportunities and performance incentives.


• Health, dental, and vision insurance.


• 401(k) plan with company match.


• Paid time off and holidays.


• Opportunities for training and advancement in advanced manufacturing and engineering support roles.
