Job description

Purpose of the Position: The Principal Research Scientist I, Step 4, will conduct advanced research and development in multilayer optical coatings, instrument hardware, and computational modeling to enable advancements in X-ray optic technology for astrophysical and high-energy applications. The scientist will collaborate closely with NASA Marshall Space Flight Center’s (MSFC) X-ray Astronomy Group under existing cooperative agreements to design, fabricate, and test reflective optical elements and to develop data-driven software tools that enhance instrument performance and coating precision. Duties / Responsibilities: Optical Coating Design and Fabrication: • Develop, optimize, and characterize single-layer and multilayer reflective coatings for hard X-ray mirrors and full-shell optics. • Support thin-film deposition studies using magnetron sputtering systems and related techniques, including layer-thickness control, interface quality improvement, and environmental stability studies. Instrumentation and Hardware Development: • Participate in the design, assembly, and validation of laboratory instrumentation and coating facilities used for optical deposition and metrology. • Support the development of test hardware for characterizing mirror reflectivity, roughness, and uniformity. • Collaborate with engineering teams on optical component integration into flight-like telescope assemblies. • Participate in study teams for the development of new mission concepts and support relevant aspects of current flight projects. Computational and Software Development: • Build and maintain computational models for X-ray reflectivity, multilayer optimization, and performance prediction from the soft to hard X-ray bandpass, including lower gamma-ray energies. • Implement and train physics-informed and machine-learning algorithms for parameter optimization, data interpretation, and control automation of coating processes. • Develop MATLAB/Python-based simulation tools and GUIs for reflectivity analysis and data processing. • Apply improvements and updates to motion control software as new hardware is integrated into laboratory systems. Data Analysis and Reporting: • Conduct quantitative analysis of X-ray reflectivity (XRR) and synchrotron data to extract optical constants, interface roughness, and depth-dependent parameters. • Document experimental findings, maintain research records, and contribute to technical reports, NASA deliverables, and peer-reviewed publications. Collaboration and Personal Development: • Work with multidisciplinary teams across NASA, academia, and industry to advance technology readiness levels of X-ray instrument technologies (TRL). • Contribute to proposal preparation for external funding and participate in internal research planning meetings. • Pursue an independent astrophysics research program, time permitting, to maintain a strong knowledge base in the field. • Contribute to the community through service and participation in peer reviews, scientific organizing committees, scientific conferences, and research collaborations. Minimum Requirements: • Ph.D. in Physics, Optical Engineering, Materials Science, or a related discipline. • Minimum of 9 months of verifiable full-time work experience. • Demonstrated expertise in thin-film deposition, optical coatings, or multilayer mirror development. • Proficiency in computational modeling using Python, MATLAB, or equivalent scientific software. • Experience with optical metrology, vacuum systems, or instrument integration. • Excellent written and verbal communication skills and the ability to work collaboratively in multidisciplinary research environments. Desired Qualifications: • Experience with hard-X-ray or extreme-ultraviolet optics, multilayer design codes, or synchrotron reflectivity measurements is desired. • Familiarity with machine-learning or AI-based optimization methods for physical systems is desired. • Prior collaboration experience with NASA or national laboratories is preferred.
