Senior Machinist: CNC / GD&T / G&M Code / Setup at iRocket · Hauppauge

Role overview

We’re hiring a Senior Machinist: CNC / GD&T / G&M Code / Setup with hands-on experience setting up and running multi-axis CNC equipment. You’ll own setups end-to-end, help prove out new programs, and support both R&D builds and short production runs.

What you’ll do

• Read and interpret engineering drawings, setup sheets, and related documentation; apply GD&T requirements.
• Set up and operate multi-axis CNC milling and turning equipment (including mill-turn / live tooling where applicable).
• Configure workholding and fixtures (vise, soft jaws, tombstones, custom fixtures) per setup documentation and best practices.
• Run, validate, and help prove out new CNC programs; support first-article / first-piece verification.
• Diagnose machining issues and make minor program/parameter adjustments (feeds/speeds, offsets) during runs.
• Perform in-process and final inspection using standard precision metrology tools; document results as required.
• Maintain machines and work area (basic preventive care, cleanliness, chip/coolant management).
• Adapt between fast-turn prototype/R&D work and short-run production while maintaining quality and repeatability.

About the team

The CNC Machining team works directly with the engineering and manufacturing teams to produce precision components for propulsion and vehicle systems.
