Job Requisition: Machine Shop Operator (Operator 3)

Position Summary

We are seeking a skilled and self-sufficient Machine Shop Operator (CNC Machinist) to support precision machining, prototyping, and equipment build activities. This role requires the ability to independently set up, operate, and troubleshoot machining processes while maintaining high standards for quality, safety, and efficiency.

The ideal candidate thrives in a low-volume / high-mix prototyping environment and collaborates closely with engineering teams to deliver complex components for robotics and automation systems.

Key Responsibilities

CNC Setup & Operation

• Independently set up and operate CNC mills, lathes, and manual machines
• Load, verify, and execute CNC programs; perform basic program edits (offsets, feeds/speeds)
• Select and install tooling, workholding, and fixtures for each job
• Run first articles and transition to stable production runs

Machining Execution

• Produce precision-machined components to engineering specifications
• Read and interpret complex mechanical drawings and GD&T
• Manage multiple jobs and priorities in a fast-paced shop

Inspection & Quality Control

• Perform in-process and final inspections using precision metrology tools
• Validate parts against tolerances and surface finish requirements
• Identify non-conformances and take corrective action

Troubleshooting & Optimization

• Diagnose machining issues (tool wear, chatter, dimensional drift)
• Adjust programs, tooling, and setups to improve part quality and cycle time
• Recommend manufacturability improvements to engineering

Equipment Ownership

• Conduct routine machine maintenance (coolant, lubrication, cleaning)
• Maintain tooling readiness and organization (5S discipline)
• Escalate equipment issues as needed

Safety & Compliance

• Follow all machine shop safety standards, including PPE and machine guarding requirements
• Perform pre-operation safety checks and hazard identification
• Ensure safe machine operation and adherence to established procedures

Cross-Functional Collaboration

• Work directly with engineers on prototype builds and iterations
• Provide feedback on part design for manufacturability (DFM)
• Support continuous improvement initiatives

Required Qualifications

• High school diploma or equivalent
• 3–5+ years of CNC machining experience (mills and/or lathes)
• Strong ability to read and interpret blueprints and GD&T
• Experience using precision inspection tools (micrometers, calipers, etc.)
• Solid understanding of machining processes, tooling, and materials

Preferred Qualifications

• Technical certification or associate degree in machining/manufacturing
• Experience in prototype or R&D machine shop environments
• Familiarity with multi-axis machining (4/5-axis)
• Basic G-code knowledge or program editing capability
• Experience with Haas, Mazak, Mori Seiki, or similar platforms
• Exposure to robotics, automation, or semiconductor equipment

Key Competencies

• High attention to detail and quality ownership
• Strong problem-solving and troubleshooting capability
• Ability to manage multiple concurrent jobs
• Effective communication with engineering and operations teams

Work Environment

• Machine shop environment with CNC and manual equipment
• Exposure to noise, moving machinery, and metalworking processes
• Required use of PPE including safety glasses, gloves, and appropriate attire
