If you thrive in a collaborative environment and are driven to deliver operational excellence, we invite you to apply and join our team.

This is an onsite role in Cedar Rapids, IA and is eligible for relocation.

What You Will Do Provide technical leadership for photolithography processes

Establish and maintain critical process parameters, equipment calibration methods, SPC limits, acceptance criteria, and advanced monitoring strategies for lithography systems.

Support troubleshooting of issues involving CD variation, resist adhesion, profile defects, contamination, overlay accuracy, pattern collapse, and environmental sensitivities.

Partner with Manufacturing Engineering, Process Engineering, Quality, Operations, and Design to investigate nonconformances, yield excursions, and process variation using structured root‑cause analysis and corrective actions.

Develop, optimize, qualify, and standardize photolithography and wafer process flows to improve yield, cycle time, equipment utilization, and cost.

Lead continuous improvement initiatives targeting defect reduction, overlay accuracy, CD uniformity, and reduction of rework and process variability.

Develop and maintain photolithography specifications, work instructions, process controls, and best‑practice guidelines.

Support qualification and integration of new photoresists, mask sets, exposure tools, metrology systems, and wafer materials.

Lead root‑cause analysis and corrective actions for lithography‑related yield losses and production issues.

Support new product introduction, process validation, PFMEA, control plans, mask review, and production readiness.

Ensure all processes comply with customer, regulatory, environmental, safety, and industry requirements
