Sr. Diamond Turning Engineering Technician

Senior Diamond Turning Engineering Technician

Industry: Ultra-Precision Manufacturing | Advanced Optical Systems

Travel: 10-15% (As needed)

Reports to: Engineering Manager

Compensation: $90-110K annual salary + variable compensation

A highly respected, growth-oriented advanced manufacturing organization is seeking a Senior Diamond Turning Engineering Technician to lead and elevate its Single Point Diamond Turning (SPDT) operations.

This is not a standard CNC role.

This position sits at the intersection of ultra-precision machining, tooling engineering, motion control optimization, and process innovation, supporting the production of optically functional surfaces manufactured at the limits of tolerancing.

This is a role for someone who thrives on solving complex manufacturing challenges and pushing the limits of what’s possible in precision machining. The organization serves demanding, high-technology markets where precision is non-negotiable and performance expectations are extreme.

This is a highly visible, high-impact role within a technically sophisticated environment.

• Work on optically critical components requiring extreme form and finish precision.
• Influence machining strategy, tooling design, and machine control at a systems level.
• Drive measurable improvements in yield, throughput, and process capability.
• Operate in a collaborative, engineering-driven culture.
• Mentor and shape the next generation of ultra-precision technicians.
• Be the technical authority in a high-performance SPDT environment.

• Lead setup, programming, and operation of SPDT machine tools for ultra-precision optical components.
• Develop and optimize machining processes to meet extreme form and surface finish requirements.
• Generate and refine advanced CNC toolpaths using Mastercam and related platforms.

• Design and optimize custom diamond cutting tools (geometry, edge prep, application tuning).
• Engineer advanced fixturing/work holding systems to ensure alignment and repeatability.
• Collaborate with internal teams and external vendors to improve tool performance and lifecycle.

• Analyze machine dynamics including vibration, spindle behavior, and thermal effects.
• Perform PID tuning and motion control optimization.
• Troubleshoot process deviations using structured root cause analysis.

• Partner with Quality, Metrology, and Production teams to ensure inspection alignment.
• Drive improvements in cycle time, yield, and process capability.
• Provide technical mentorship to diamond turning technicians across shifts.

• Ensure preventative maintenance and machine condition monitoring.
• Maintain rigorous process documentation and parameter control.
• Uphold precision manufacturing safety and cleanliness standards.

• 5+ years of diamond turning experience in ultra-precision manufacturing.
• Advanced proficiency in Diffsys and Mastercam.
• Proven expertise in diamond tool design and optimization.
• Experience designing advanced fixturing for tight-tolerance components.
• Strong knowledge of motion control systems and PID tuning.
• Demonstrated ability to improve process capability and surface quality.

• Background in optical component manufacturing.
• CNC machining and advanced metrology experience.
• Experience with closed-loop compensation strategies or automation integration.
