Senior Microfabrication Engineer – Optics & Materials

Johns Hopkins Applied Physics Lab; Laurel (MD); On-site; USD 105,000 - 290,000; Full time

Job summary

The Johns Hopkins Applied Physics Laboratory (APL) in Laurel, MD seeks a Senior Electronic and Optical Materials Device Fabrication Engineer to lead fabrication of world-class micro- and nanoscale devices in a cleanroom environment. You will design multilayer layouts, develop deposition recipes, and implement data-driven automation linking design, fabrication, and metrology data.

You'll apply AI/ML to improve processes, refine deposition techniques across multiple systems, and characterize films

Qualifications

• Master's degree in Materials Science and Engineering or related field.
• 7+ years experience in microfabrication/nanofabrication cleanroom environment.
• Proficiency in multilayer layout design and Python scripting for design automation and data analysis.
• Experience optimizing etch and deposition processes (thermal evaporation, e-beam, sputtering, PECVD, ICP RIE, ion mill).
• E-beam lithography experience is required for this posting.
• Willingness to travel locally to shared cleanrooms and labs.
• Eligibility for Interim Secret clearance and potential Top Secret clearance; U.S. citizenship required.

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.
• Build and maintain GDS/layout databases with Python automation for layout generation, fracturing, and DRL checks; link data across design, fabrication and metrology.
• Apply AI/ML approaches to improve fabrication processes.
• Refine deposition techniques across e-beam, thermal, sputter, PECVD, ALD, MOCVD to enhance device quality.
• Characterize thin films and processes using SEM/EDS, XPS, XRD, AFM, ellipsometry, film stress analysis.
• Execute precision etching processes to meet tight design specs and tolerances.
• Maintain and update runsheets and process documentation for accuracy and repeatability.
• Collaborate with teams to drive fabrication workflow improvements.
