Optical Systems Engineer (104777)

KLA-Tencor's Surfscan Division, a market leader in the unpatterned wafer inspection business, is looking to recruit a highly adaptive UV optical systems engineer with laser/lens design familiarity. The succesful candidate will support the fabrication, alignment, and integration processes for the SP2 and SP3 products - flagship product lines for a $1B+ semiconductor capital equipment manufacturer.  The candidate will interact with the most dynamically integrated and UV knowledgeable companies in the optics industry to improve upon opto-mechanical module solutions having sufficient degrees of freedom to meet module performance, manufacturability, and serviceability goals while not destabilizing the overall optical system.  In improving upon these highly-robust, opto-mechanical modules, careful attention to all fabrication details will be required to achieve all critical performance criteria including transmitted wavefront, transmission, scatter, absorption, polarization, spot size, etc.  Additional development details for the optical system integration process, alignment methods, and metrology pass/fail guidelines both during factory integration and during customer operation in the field must be carefully defined and well documented to avoid cost and cycle time overruns from the program specific goals.

Candidate will also have opportunities to interact in a cross functional team which includes marketing, manufacturing, and global service teams to fully understand improvement goals and requirements.

Some travel will be required to visit top end suppliers and to support designs on high level customer escalations.

 

Qualifications:

Candidate must have the following: Bachelor's degree with at least 10 years of experience, Master's degree with at least 8 years of experience, or PhD with at least 7 years of experience in the optical design and engineering fields.  Candidate should also have all requisite skills to tolerance allocate/budget and assemble/test optical subsystems/modules while handling multiple vendor interactions and internal/external design reviews.  This would include but is not limited to proficiency in sequential ray tracing codes (CodeV or Zemax) and exposure to at least one non-sequential (3D) modeling tool (Zemax, LightTools, ASAP, FRED) to simulate and perturb both individual components and/or entire subsystems.  Candidate must demonstrate track record of successful completion of internal project milestones and deliverables on time and with limited supervision.  Ability to travel both in US and abroad is required.  System level design and characterization experience is a plus.
