Associate Electronic and Optical Materials Device Fabrication Engineer

About the role

We are seeking a Junior Electronic and Optical Materials Device Fabrication Engineer to help us fabricate world-class micro- and nanoscale devices. The role is predominantly fabrication-focused, with a vast majority of working hours spent in a cleanroom or laboratory environment.

Responsibilities

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

Qualifications

• Have a Bachelor's Degree in Materials Science and Engineering, Physics, Electrical Engineering, or related field.
• Have 2+ years of experience working in a microfabrication or nanofabrication cleanroom environment.
• Be proficient in multilayer layout design and modification, with expertise in Python scripting for both design automation and data analysis.
• Have experience optimizing etch and deposition processes, including thermal evaporation, e-beam, sputtering, PECVD, ICP RIE, and ion mill techniques.
• Be willing and able to travel locally to shared cleanrooms and laboratory facilities.
• Able to obtain Interim Secret level security clearance by your start date and can ultimately obtain Secret level clearance.
