The Materials Development and Manufacturing Technology Group at NASA’s Jet Propulsion Laboratory, California Institute of Technology is seeking a postdoctoral scholar for basic science research related to the development of bulk metallic glasses (BMGs) and their related composites. JPL runs a premier research laboratory on BMGs, with a well-established record in the academic community and in industry. Previous research has been related to alloy development, suction casting, injection molding, development and testing of gears, infrared imaging science, rapid capacitive discharge welding, cellular structures, spacecraft debris shielding, compliant mechanisms and flexures, mirrors, inserts, and the development of ultratough composites. A postdoctoral scholar is sought who has a Ph.D. directly related to the development and mechanical properties of BMGs and could immediately make contributions to the areas listed above. The candidate is expected to rapidly integrate into the laboratory and perform independent scientific research in support of current NASA programs. The candidate is expected to vigorously lead, perform and publish peer-reviewed scientific papers and file relevant intellectual property. The candidate will have access to two arc-melters, two FLIR infrared thermal cameras, injection molding equipment, thermoplastic forming equipment, vacuum chambers, RF power supplies, metallography equipment, gear testing equipment, a load frame, microscopes, Vicker’s hardness tester, machining capability and 3D polymer printers all within the primary group. The candidate will also have access, where appropriate and where funding permits, to other JPL groups and resources. The intent of the postdoctoral position is to do independent scientific research with little physical support. As such, the candidate must be able to perform all relevant experiments, fix and maintain equipment, perform all microscopy or characterization, and completely write scientific publications based on the results with limited input from others.
