CNC Machining Technician II - 2nd Shift

• Independently set up, operate, and optimize CNC machining centers (HAAS, Mori Seiki, or equivalent) for precision operations on glass, ceramic, and crystalline substrates including:
  • Edging and diameter generation to tight tolerances
  • Beveling, chamfering, and edge profiling
  • Profile machining, contouring, and specialty material removal operations
• Select, mount, and qualify tooling (diamond grinding wheels, cutting tools, fixtures) appropriate for the material and operation.
• Read and interpret machining drawings, optical drawings, work travelers (manufacturing routing documents), and specifications.
• Write, edit, and verify G-code programs; make in-process program adjustments to optimize cycle time, surface finish, and dimensional accuracy.
• Perform in-process and final dimensional inspection using precision metrology tools including:
  • Micrometers, calipers, and electronic/dial indicators
  • Optical comparators
  • Height gauges and bore gauges
  • Surface finish gauges and edge inspection tools
• Monitor tool wear, chipping, and breakage; manage tool life and replacement schedules.
• Troubleshoot machining issues including chatter, runout, thermal drift, chipping, and breakage on brittle substrates; identify root causes and implement corrective actions.
• Maintain process records, job logs, labels, and traceability documentation using shop-floor systems.
• Perform routine machine maintenance including coolant management, way lubrication, spindle checks, and fixture upkeep; support preventive maintenance schedules.
• Work with supervisors, quality, and engineering to resolve process or quality issues and support new part introduction.
• Mentor and train CNC Machining Technician I personnel on setup standards, safe machine operation, workmanship expectations, and documentation practices.
• Contribute to continuous improvement initiatives to improve yield, cycle time, tool life, and process repeatability.

• High school diploma or equivalent.
• 3+ years of CNC machining experience, preferably with non-metallic materials (glass, ceramics, or similar brittle substrates).
• Proficiency in CNC machine setup, operation, and basic troubleshooting on HAAS, Mori Seiki, or equivalent machining centers.
• Working knowledge of G-code programming, including the ability to write, read, edit, and verify programs.
• Ability to read and interpret machining drawings, blueprints, and specifications.
• Proficient shop math skills including algebra, geometry, trigonometry, fractions, ratios, and decimal arithmetic.
• Strong skills in dimensional measurement using precision inspection tools.
• Strong attention to detail, documentation discipline, and process consistency.
• Good communication and teamwork skills.

• Experience machining optical glass, technical ceramics, or crystalline materials.
• Experience with diamond tooling selection and management for brittle material machining.
• Familiarity with coolant systems, filtration, and waste management for glass/ceramic machining.
• Experience with CAM software for toolpath generation.
• Familiarity with shop-floor software, ERP/MRP systems, and production data systems.
• Experience in aerospace, defense, semiconductor, or other high-spec manufacturing environments.
• Familiarity with GD&T (Geometric Dimensioning and Tolerancing) principles.

• Meaningful work producing precision optical and ceramic components for defense, aerospace, and advanced technology programs.
• A team-oriented shop with opportunities to grow into senior technical or leadership roles.
• Access to modern CNC machining centers and precision metrology tools.
• A company that values craftsmanship, process discipline, and continuous improvement.
• Collaboration with engineering and quality teams on process development and new part introduction.

• Standing for extended periods; frequent hands-on machine setup, operation, and part handling.
• Must be able to regularly lift and carry up to 25 lbs and occasionally up to 50 lbs.
• Use of hands and fingers to handle, feel, or manipulate delicate optical and ceramic components, tooling, and fixtures.
• Specific vision abilities required include close vision, color vision, depth perception, and the ability to adjust focus.
• Work is performed in a controlled manufacturing environment; noise level is generally moderate. Use of coolants, cutting fluids, and standard machine shop PPE is required.

• Paid vacation and holidays
• Health, dental, and vision insurance
• 401(k) with employer matching
• Life insurance and short-term disability
• Day shift schedule, Monday through Friday
