Job description

Aptask Global Workforce (AGW) is seeking a Diamond Turning Machine Operator Technician for a position with a Global Aerospace and Defense Technology Company located in Tustin, CA.

In this role, you will be responsible for setting up, programming, and operating single-point diamond turning (SPDT) equipment to produce sub-micron level tolerance optical components and high-precision mechanical assemblies. The ideal candidate possesses a strong background in CNC machining, ultra-precision metrology, and interpreting standard optical blueprints.

Responsibilities:

• Set up and operate multi-axis ultra-precision diamond turning lathes to fabricate complex optical surfaces (aspheric, diffractive, off-axis)
• Read, interpret, and make minor edits to CNC programs directly on machine controllers
• Perform critical post-process inspections using advanced metrology equipment like interferometers, profilometers, and microscopes
• Monitor tool wear, adjust feeds and speeds, and execute optical alignment adjustments to optimize part quality
• Conduct routine preventative maintenance on fluid/air systems and maintain strict compliance with ISO 9001 quality standards

Requirements:

• High school diploma or GED equivalent; technical certification or associate degree in precision machining is preferred
• Minimum of 2 years of CNC machining experience; direct experience in single-point diamond turning or precision optics fabrication is highly valued
• Proven capability to interpret engineering blueprints, GD&T symbols, and complex technical drawings
• Solid understanding of basic algebra and geometry for calculating machine angles and part proportions
• Familiarity with micro-inch tolerances and precise part handling techniques

Desired skills:

• Experience with specific diamond turning controller programs (e.g., Precitech or Moore Nanotech software systems)
• Experience machining varied substrates including crystalline materials (Germanium, Silicon), and non-ferrous metals (Aluminum)
• Strong problem-solving abilities and exceptional attention to detail

Salary range:

from $58,032.00 to $78,228.80 per year
