CNC Machinist I - 3rd Shift with 10% Differential

Rochester Precision Optics, LLC; Bailey (NY); On-site; USD 36,000 - 40,000; Full time

Benefits offered by this job

Shift differential

Job summary

Rochester Precision Optics, LLC is seeking a CNC Machinist I for third shift to operate, monitor, and optimize CNC machining processes in a high-precision production environment. You will work from established programs, inspect parts, and adjust tooling and offsets to ensure tight tolerances.

The role requires reading blueprints, GD&T, and performing advanced metrology. Training on 1st shift precedes transition to 3rd shift with a 10% shift differential and overtime as needed.

Qualifications

• Minimum 3 years of CNC machining in a precision manufacturing environment.
• Ability to read and interpret engineering drawings, blueprints, specifications, and GD&T requirements.
• Proficiency with precision inspection equipment including micrometers, calipers, indicators, height gauges, thread gauges, optical comparators, and similar metrology tools.
• Willingness to review and perform minor program edits in G-code/M-code when required.
• Understanding of feeds, speeds, tool wear, cutting tool selection, and process control.
• Commitment to safety, quality, attention to detail, and continuous improvement.

Responsibilities

• Review and interpret engineering drawings, blueprints, specifications, routers, and work instructions to understand part requirements, tolerances, and machining processes.
• Operate CNC mills, lathes, and other machining equipment using established programs, setups, and process documentation.
• Monitor machining operations and adjust offsets, tooling, feeds, speeds, and process parameters to maintain dimensional accuracy, quality, and productivity.
• Perform advanced in-process and final inspections using micrometers, calipers, indicators, height gauges, thread gauges, optical comparators, and other precision measuring equipment.
• Verify product conformance to dimensional, geometric, and cosmetic requirements and ensure all quality standards are met.
• Troubleshoot machining, tooling, quality, and process-related issues and communicate concerns to technical leads or management as appropriate.
• Perform tooling changes, tool life monitoring, and wear compensation to maintain stable machining processes.
• Assist with machine setup activities, process validation, and first-piece verification when required.
• Maintain accurate production, inspection, maintenance, and ERP documentation.
• Support continuous improvement initiatives focused on quality, efficiency, throughput, scrap reduction, and cost savings.
• Train, assist, and support less experienced operators as needed while promoting best practices within the department.
• Perform and document routine operator-level preventative maintenance activities.
• Maintain a clean, organized, and safe work environment.
• Be available for occasional overtime to support production requirements.
