About the Role

A leading U.S. military defense contractor is seeking a highly skilled Engineer Machinist to support the design, fabrication, and precision machining of critical defense components. This individual will play a central role in manufacturing, prototyping, and modifying high-precision parts for military applications, ensuring they meet strict quality, tolerance, and performance standards.

The Engineer Machinist will work closely with engineering teams, quality control specialists, and production personnel to support the development of mission-critical defense systems. This is a full-time, on-site position at a secure U.S. defense facility, and candidates must be prepared to operate within a classified environment subject to strict security protocols and regulatory oversight.

Key Responsibilities

Precision Machining and Fabrication

  • Operate, program, and maintain CNC and manual machining equipment to manufacture high-precision components to exact engineering specifications.
  • Work from engineering blueprints, technical drawings, and CAD/CAM software to produce parts within required tolerances for military and aerospace applications.
  • Set up, calibrate, and adjust machining equipment prior to production runs, verifying correct tooling, fixturing, and workholding configurations.

Engineering Collaboration and Prototyping

  • Collaborate with design and manufacturing engineers to develop prototypes, modify existing components, and refine machining processes to support program requirements.
  • Participate in design reviews, process engineering discussions, and production planning meetings to provide machinist input on manufacturability and feasibility.
  • Support research and development teams in fabricating test articles and proof-of-concept components for emerging defense systems.

Quality Assurance and Metrology

  • Conduct precision measurements and dimensional inspections using micrometers, calipers, CMMs, and other metrology instruments to verify part tolerances and conformance to drawing requirements.
  • Ensure compliance with military and aerospace-grade quality standards including AS9100 and applicable ISO certifications throughout the production process.
  • Document non-conformances and work with quality control staff to identify root cause, implement corrective actions, and prevent recurrence.

Process Optimization and Continuous Improvement

  • Optimize machining processes by identifying and implementing lean manufacturing principles, cycle time reductions, and continuous improvement techniques.
  • Troubleshoot and resolve machining and manufacturing issues, ensuring efficiency, dimensional accuracy, and consistency across production runs.

Compliance, Documentation, and Security

  • Maintain accurate and thorough documentation of machining processes, setups, and inspection results to ensure full traceability and compliance with government and defense contract regulations.
  • Adhere strictly to security protocols and material handling requirements for classified components, sensitive materials, and controlled technical data.
  • Ensure all work is performed in compliance with ITAR regulations, export control requirements, and applicable defense contract quality provisions.

Cross-Functional Participation

  • Participate in cross-functional teams supporting research, development, and production goals across multiple program areas.
  • Mentor junior machinists and production technicians, sharing expertise in CNC programming, precision setup, and quality verification techniques.

Education and Experience Requirements

Education
Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or a closely related field preferred. Equivalent experience in precision machining combined with relevant technical training or apprenticeship will be considered.
Experience
Five or more years of experience in a machining or manufacturing environment, preferably within the defense, aerospace, or military sectors. Demonstrated proficiency in CNC programming using G-code and M-code, and CAD/CAM software including MasterCAM, SolidWorks, or Siemens NX.
Technical Knowledge
Strong understanding of materials science, metallurgy, and machining best practices for military-grade components. Experience with GD&T and the ability to interpret complex technical drawings accurately. Knowledge of military and defense manufacturing standards including ITAR compliance requirements.
Security and Environment
Ability to work in a high-security, classified environment with strict adherence to defense industry regulations and security protocols. U.S. citizenship required. Candidates may be required to obtain a government security clearance based on specific project assignments.

What the Organization Offers

Compensation
Competitive salary based on experience and prevailing defense industry standards for precision machining expertise.
Benefits
Comprehensive benefits package including medical, dental, vision, 401(k) with employer contribution, and paid time off.
Career Development
Opportunities for career advancement and professional development within a leading U.S. defense contractor with long-term program pipelines.

Why This Role Matters

Defense manufacturing tolerances leave no room for error. The components produced in this role go directly into systems that military personnel depend on in the field — making precision, quality discipline, and regulatory compliance not abstract professional values but operational necessities. The Engineer Machinist who performs this work contributes directly to national security outcomes.

For a skilled machinist with defense or aerospace background who wants to work at the intersection of advanced manufacturing and mission-critical application, this is one of the more substantive opportunities available in the sector. The work is technically demanding, the standards are uncompromising, and the stakes are real.

In defense manufacturing, precision is not a preference. Every tolerance matters, every inspection counts, and the work that leaves this facility has to be right the first time.
