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.

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 end station is a high throughput/operando bulk XAS end station. The tender x-ray microspectroscopy end station is a micro beam end station 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.

• 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 beamline's 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 beamline's 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

• PhD in 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
• Knowledge of x‑ray imaging or fluorescence imaging 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

• PhD in Physics, Chemistry, Materials Science, or other relevant fields with minimum…
