The National Synchrotron Light Source-II (NSLS-II) is a DOE-funded scientific user facility at Brookhaven National Laboratory. The Spectroscopy Program within the Physical Sciences & Research Operations Division provides advanced X-ray spectroscopy tools to study complex materials under real-world conditions with a focus on understanding and improving materials used in energy storage catalysis and other applications involving non-ambient and complex dynamic environments. The program includes four NSLS-II operated beamlines as well as three partner beamlines stewarded by NIST covering soft tender and hard X-ray spectroscopy.

Position Description

The National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory seeks a Lead Beamline Scientist for the Tender Energy X-ray Absorption Spectroscopy (TES) beamline. TES is a tender-energy beamline for XAS and X-ray fluorescence imaging in the 2-5.5 keV energy range and will be upgraded to 1.7 8.3 keV. The beamline serves a broad range of scientific user communities including catalysis energy geochemistry environmental and bioscience. TES beamline has two endstations. The Smart XAS endstation is a high throughput/operando bulk XAS endstation. The tender x-ray microspectroscopy endstation is a micro beam endstation with beam size 5 um focused using KB mirrors which is currently being upgraded and will be commissioned in 2026.

As the Lead Beamline Scientist for TES the successful candidate will work closely with a multidisciplinary team including beamline scientists data analysis scientists technicians engineers and other support staff to lead both the TES user program and beamline operations. The Lead Beamline Scientist will develop a vision and strategy to advance the TES user science program enhance the beamline capabilities and propose facility improvements and upgrades to ensure that the TES beamline remains at the state-of-the-art.

Essential Duties and Responsibilities:

• Refine and evolve the mission and technical scope of the TES beamline by interacting effectively with the scientific user community and with the Spectroscopy Program and NSLS-II colleagues

• Grow the TES beamlines scientific program in line with the NSLS-II strategic plan and support the facility mission with a focus on x-ray spectroscopy and microscopy

• Lead the safe operation of the TES beamline and provide oversight of staff and users working at the beamline

• Supervise a team of beamline scientists assigned to the TES beamline

• Propose and manage the TES operating budget beam time allocation and schedule

• Oversee the design implementation maintenance and upgrade of the beamline equipment and guide the beamlines progress with advanced data management and analysis

• Collaborate with NSLS-II staff BNL scientists and/or external researchers to develop an independent scientific or technical research and development program that leverages or enhances the unique capabilities of the TES beamline

• Coordinate the TES user program with those of other NSLS-II beamlines within and outside the Spectroscopy Program that offer complementary techniques or capabilities

Required Knowledge Skills and Abilities:

• Physics Chemistry Materials Science or other relevant fields with minimum 6 years experience in synchrotron-based research with significant experience using x-ray spectroscopy and/or imaging techniques

• Knowledge of x-ray spectroscopy fundamentals and data analysis

• Strong publication record in using X-ray spectroscopy and/or imaging techniques

• Excellent written and communication skills

• Ability to interact effectively in a team environment with a diverse group of scientists engineers technical staff and users

Preferred Knowledge Skills and Abilities:

• Physics Chemistry Materials Science or other relevant fields with minimum 10 years experience

• Demonstrated successful experience with synchrotron beamline operation and user support

• Significant experience using 2D or 3D x-ray fluorescence microscopy.

• Proven expertise in DFT and/or XANES simulation

• Hands-on experience with in-situ and operando measurement

• Demonstrated success in the design installation and/or commissioning of a synchrotron radiation beamline
