Senior Electronic and Optical Materials Device Fabrication Engineer

Senior Electronic and Optical Materials Device Fabrication Engineer role focused on hands-on fabrication of micro- and nanoscale devices in cleanroom environments.

Responsibilities

• Design and optimize multilayer layouts using Python scripting for layout generation and data analysis
• Develop advanced fabrication recipes for multilayer optics using e-beam lithography and direct-write lithography on optical substrates
• Build and maintain version-controlled GDS/layout databases with Python automation for parametric layout generation, fracturing, and design rule checking
• Create data-analysis pipelines that connect design, fabrication, and metrology to track CD, overlay, and yield trends
• Apply AI and machine learning to improve fabrication processes
• Refine deposition workflows across systems including e-beam, thermal, and sputter evaporators, plus PECVD, ALD, and MOCVD to improve device quality
• Characterize thin films and processes using tools such as SEM/EDS, XPS, XRD, AFM, ellipsometry, and film stress analysis
• Run precision etching to meet tight design specifications and tolerances
• Maintain and update process documentation, including runsheets, to support accuracy and repeatability
• Collaborate with teams to innovate and improve fabrication workflows

Requirements

• Master’s degree in Materials Science and Engineering, Physics, Electrical Engineering, or a related field
