• Own process development and optimization for SpeedFam 22B, OptiPro GlassMaster 720, and equivalent equipment.
• Design and qualify carriers for new part geometries; specify pocket placement, eccentricity, and pressure distribution to achieve target figure and parallelism.
• Apply planetary kinematics speed ratio (k), relative velocity, and Preston equation fundamentals to predict and control removal rate and uniformity.
• Troubleshoot common DSP/DSL failure modes: center-to-edge non-uniformity, carrier wear, pad glazing, part chipping, and carrier-induced scratching.

• Lead prism angle fabrication including right-angle, Dove, Penta, Schmidt, and roof prisms; control pyramidal error, angle tolerance, and 90° squareness to arc-second levels.
• Specify and execute wax blocking, pitch button blocking, and array blocking strategies for prism and wedge production.
• Apply blocking-plate wedge analysis to predict and control cross-wedge and thickness variation in array-blocked components.
• Develop multi-element assembly and de-blocking procedures that protect finished surfaces.

• Operate Zygo GPI/Fizeau and NewView interferometers; interpret MetroPro / MX output including Zernike decomposition, PV/RMS figure, slope, and PSD/MSF analysis.

• Specify and apply MIL-PRF-13830B and ISO 10110 surface quality, figure, wedge, and centration requirements on engineering drawings.
• Use ZEISS CALYPSO CMM, Prism Master, autocollimators, and mechanical inspection tools to qualify dimensional and angular tolerances.
• Partner with Quality to drive FAI (AS9102), Gage R&R, and corrective action for fabrication yield issues.

• Author and maintain work instructions, SOPs, and process travelers for conventional fabrication operations in ERP system.
• Lead root-cause analysis on yield loss, scrap, and rework; implement preventive measures with measurable impact.
• Evaluate and qualify new equipment, tooling, and consumables (pitch, abrasives, carriers, blocking materials).
• Mentor Optical Fabrication Technicians I–III; support skills development, competency assessments, and training.
• Collaborate with operations on producibility reviews and design-for-fabrication feedback during quoting and program kickoff.

• 5+ years of hands-on precision optical fabrication experience in a defense, aerospace, or scientific optics production environment.
• Demonstrated expertise in conventional (non-CNC) fabrication processes: loose-abrasive grinding, pitch polishing, double-sided lapping/polishing, and prism work.
• Proven ability to independently develop and qualify fabrication processes from raw blank through finished component.
• Track record of solving complex yield, figure, or finish problems through first-principles analysis.

• Deep working knowledge of optical fabrication physics: Preston equation, Hertzian contact, SSD mechanics, and pitch rheology.
• Expert-level pitch polishing tool preparation, lap conditioning, hand figuring, and full-aperture convergence.
• Double-sided lapping/polishing experience on SpeedFam, GlassMaster, Lapmaster, or equivalent planetary machines.
• Prism fabrication experience including angle control, blocking, and arc-second measurement.
• Proficient with Zygo interferometers and MetroPro; able to interpret Zernike, PSD, and slope data.
• Able to read and interpret optical drawings per MIL-PRF-13830B and ISO 10110 (all applicable parts).
• Solid grasp of ASME Y14.5 GD&T as applied to optical components.

• Bachelor's degree in Optical Engineering, Physics, Materials Science, Mechanical Engineering, or a related technical field, with 5+ years of hands-on precision optical fabrication experience; OR
• 10+ years of directly applicable precision optical fabrication experience in lieu of a degree, with demonstrated expertise across grinding, polishing, metrology, and complex geometry work.

• Experience with continuous polishers (CP) up to 96" diameter.
• MetroScript (Zygo OMP-0399P) scripting capability for automated measurement and data analysis.
• Familiarity with QED MRF (magnetorheological finishing), ion beam figuring, or other sub-aperture deterministic processes as complements to conventional work.
• Experience with optical glass, such as N-BK7, or ceramic materials, such as Zerodur®. Experience with crystalline and IR materials (ZnS, Ge, Si, ZnSe, sapphire).
• Familiarity with AS9100 quality management system requirements.
• Working knowledge of ERP/MRP systems for production routing and travelers.
• Exposure to acid etching, MRF, or other post-polish surface treatments.
