From developing next-generation batteries and microelectronics to designing future pharmaceuticals and quantum computers, scientists tackle the world’s greatest challenges by advancing our understanding of materials. However, today's problems are so complex that they require researchers to study materials with highly specialized tools that are not readily available at most institutions. The National Synchrotron Light Source II (NSLS- II) makes such state-of-the-art tools available, together with the expertise to use them, to scientists from all over the world.

The current 29+ beamlines at NSLS-II offer the widest spectrum-from infrared to hard X-rays - of synchrotron light that enables characterization using in situ, multimodal, time-resolved diffraction, spectroscopy and microscopy. One of their core missions is to observe materials under conditions far from equilibrium, i.e., as a function of a process parameter like T, P, pH, pressure and flow of reactive gases, electric or magnetic field.

One of the strategic research directions that NSLS-II is investing in is making beamlines suited to autonomous experiments as well as high throughput measurements. This plan will enhance the scientific throughput with more fundamental insight into the time evolution of materials processing and kinetics.
** Position Description
** NSLS-II is seeking an experienced scientist to join the Tender Energy Spectroscopy (TES) beamline team. The successful candidate will work closely with the Lead Beamline Scientist to enhance beamline capabilities, drive scientific productivity, and support a growing user program. TES is a tender-energy X-ray beamline dedicated to X-ray absorption spectroscopy (XAS) and X-ray fluorescence imaging in the 2-5.5 keV energy range, with planned upgrades extending coverage to 1.7-8.3 keV.

The beamline serves a broad and interdisciplinary user community spanning catalysis, energy science, geochemistry, environmental science, and bioscience. The TES beamline operates two complementary end stations. The SMART XAS end station is a high-throughput, operando platform for bulk XAS measurements. The tender X-ray microscope end station provides micro-focused capabilities (~5 μm beam size using KB mirrors) for spatially resolved studies and is currently undergoing a major upgrade, with commissioning planned for 2026.

The selected candidate will contribute to a wide range of scientific applications, including, but not limited to, complex energy conversion and storage systems such as batteries, fuel cells, and heterogeneous catalysis.
