CNC Machinist II

ISSI Engineering & Machining is seeking a CNC Machinist II to join our precision machining team.

ISSI is a high-mix aerospace and precision machining job shop supporting a wide variety of work, from straightforward vise setups and established production jobs to expedited one-off parts and custom machining projects. Our machinists work closely with engineering, CAM programming, CMM programming, and quality to get jobs through the shop efficiently and correctly.

Why ISSI?

• Advanced CNC Technology: Work with Okuma dual-turret lathes, Makino 4 & 5 axis machining centers a DMG mill turn machine and other machine tools.
• Advanced Inspection Equipment: Access to a Zeiss CMM for complex inspection and verification.
• Growth & Innovation: Join a team that continues to invest in new equipment, technology, and capabilities.

What You’ll Do

• Set up, prove out, and operate Makino 4-axis and 5-axis machining centers on established production, expedited, and one-off work.
• Perform complex setups using precision fixtures, multiple work offsets, non-vise workholding, probing, and multi-sided machining.
• Safely prove out new and revised CAM-generated programs, verifying tooling, workholding, offsets, machine position, setup conditions, and clearances.
• Monitor and troubleshoot machining processes, including tooling, workholding, part movement, dimensional variation, surface finish, cutting conditions, setup repeatability, machine behavior, and program execution.
• Read and interpret complex engineering drawings and GD&T, perform detailed manual inspection, and recognize dimensional trends and potential process issues.
• Operate established Zeiss CMM programs, interpret inspection results, and work with CMM programming and quality when further evaluation is needed.
• Diagnose whether machining or dimensional issues are related to the setup, tooling, machine, programming, inspection, or other process variables, and work with the appropriate team to resolve them.
• Work closely with engineering and CAM programming to resolve manufacturing issues and provide practical shop-floor feedback to improve tooling, fixtures, programs, and processes.
• Serve as a technical resource for less-experienced machinists by providing hands-on guidance with setups, tooling, prove-out, inspection, and troubleshooting, while maintaining accurate setup, production, and inspection documentation.

Minimum Job Requirements

• High school diploma or equivalent preferred.
• 4-5 years of CNC machining experience, including setup and operation of complex machining processes.
• Experience with 4-axis and 5-axis CNC machining centers.
• Experience performing first-time setups, machine prove-outs, and troubleshooting machining processes.
• Experience working with complex fixtures, non-vise workholding, multiple work offsets, and multi-sided machining operations.
• Ability to read and interpret complex engineering drawings, GD&T requirements, and manufacturing documentation.
• Experience performing detailed inspections using precision measuring instruments and operating CMM equipment.
• Experience in aerospace, AS9100D, or similarly regulated quality-controlled manufacturing environments preferred.
• Ability to identify machining, tooling, setup, programming, or quality issues and work collaboratively with engineering, programming, and quality personnel to resolve them.
• Ability to mentor and support less-experienced machinists.
• Must provide basic personal precision inspection tools required for day-to-day inspection activities.
• Strong attention to quality, safety, and continuous improvement.
• Good communication and teamwork skills.
