• Evaluate and compare multiple dispensing approaches for functional layers used in AR components such as optical clear adhesives polymer layers and micro-structured materials

• Understand the rheology surface tension wetting and adhesion of ink/dispense materials and how these characteristics drive method selection and process performance

• Design and implement metrology and characterization capabilities to measure film thickness/uniformity feature geometry surface morphology alignment optical performance and defect modes

• Analyze process data using statistical methods (DOE SPC regression yield modeling) to drive significant improvements in uniformity throughput repeatability and yield

• Collaborate cross-functionally with optical engineering mechanical design materials science reliability and assembly teams to integrate new dispensing processes in AR module manufacturing

• Work with internal and external partners to develop tools for scaling up processes for mass production

• Support long-term process roadmap development identify technology gaps and lead evaluations of new dispensing tools or methods for next-generation AR hardware

Knowledge Skills & Abilities

• Expertise in inkjet printing including waveform tuning drop formation dynamics material compatibility and print quality control

• Practical experience with industrial printheads (e.g. Xaar Fuji Konica Minolta etc) and familiarity with control software (e.g. GIS Meteor) and drop watching systems

• Strong foundational grasp of fluid mechanics surface science and wetting and how material properties profoundly influence deposition outcomes

• Good understanding of thin film characterization and metrology: including profilometry interferometry reflectometry optical microscopy defect inspection and thickness measurement

• Strong experimental design analytical and problem-solving abilities; capable of independently driving complex R&D investigations from concept to completion

• An effective communicator who can collaborate seamlessly with multidisciplinary teams and clearly document processes findings and specifications

Minimum Qualifications

• Masters (or higher) degree in Materials Science Chemical Engineering Mechanical Engineering Applied Physics or a related technical field

• 5 years of hands-on experience with inkjet printing dispensing coating micro-fabrication printed electronics or precision deposition processes

• Experience working effectively in R&D labs cleanrooms or controlled-environment manufacturing settings

Preferred Qualifications

• PhD in a relevant discipline or 10 years of extensive experience in precision dispensing printed electronics advanced manufacturing or display technology

• Proven experience evaluating and selecting between multiple deposition/coating techniques based on complex material optical and mechanical requirements

• Familiarity with AR/VR optical components waveguides nanoimprinting thin-film deposition bonding and dry etching processes

• Experience in process transfer successful scale-up to mass production yield optimization and implementation of inline metrology
