Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.

Organizational Overview

The Hard X-ray Scattering & Spectroscopy (HSS) program at BNL’s National Synchrotron Light Source II (NSLS-II) offers world-class capabilities for studying complex and heterogeneous materials under in-situ and operando conditions. The program provides specialized spectroscopy, diffraction, and imaging facilities using synchrotron-generated X-ray beams, and computational resources for high-throughput analysis and modeling. Within this program, the High Energy Engineering X-ray Scattering (HEX) beamline is designed to enable time-dependent 2D and 3D imaging and diffraction with a strong focus on in-situ measurements using high-energy X-rays. The mission of the HEX beamline is to help advance clean energy technologies and creative energy storage solutions and to support engineering materials development in NY State and beyond.

Position Description

NSLS-II has an opening for a beamline scientist to join the HEX beamline team. This position is needed to develop and maintain a tomographic system consisting of a comprehensive, state-of-the-art imaging equipment, and the software for data acquisition and reconstruction in support of the scientific mission of NSLS-II. Working together with the HSS program staff, the successful candidate will support the high volume user research program at the HEX beamline. The candidate is expected to engage in internal and external scientific collaborations that leverage the unique capabilities of the beamline. The candidate will be involved in commissioning, maintaining and upgrading the instrumentation and the software for optimized, fast, full-field imaging using hard X-rays. The candidate’s responsibilities will include user support, design of complex in-situ and operando experimental protocols, and particularly the active support of development of data analysis and processing protocols in collaboration with the Data Science & Systems Integration (DSSI) team.

Essential Duties and Responsibilities:

  • Work with a team of scientists and software engineers to define and implement the best strategies in X-ray imaging instrumentation and scientific data handling
  • Support HEX users during their measurements at the HEX beamline and advise them on data-reduction and reconstruction.
  • Take the lead in developing new computational approaches and methods to extract maximum scientific information from experimental data.
  • Collaborate with other DOE facilities active in the field of synchrotron-based tomography.
  • Present work and results at scientific meetings, and travel to multiple scientific facilities throughout the world.

Position Requirements

Required Knowledge, Skills, and Abilities:

  • Ph.D. degree in Physical Science, Materials Science, Applied Mathematics or related field.
  • At least 4 years of hands-on experience in operating and maintaining X-ray imaging instrumentation
  • Established expertise with experimental protocols and data acquisition at either a synchrotron beamline or at a lab CT-machine.
  • Significant contributions to the field of computed tomographic data reduction, reconstruction, or analysis.
  • Working experience in scientific computing or large scale data management in a Linux environment.
  • Employed open-source and commercial software for image reconstruction.
  • Demonstrated experience in Python and C/C++.
  • Excellent communications and interpersonal skills to interact effectively with a diverse group of scientists, engineers, and technical staff.
  • Excellent written and oral communications skills.

Preferred Knowledge, Skills, and Abilities:

  • Performed user-oriented activities such as local contact duties.
  • Demonstrated collaborations in the field of X-ray tomography.
  • Familiar with the working principles of imaging sensors, visible light scintillators, and optical coupling.
  • Working experience in the use of X-ray optics such as monochromators and mirrors for hard X-rays.
  • Proficiency in the use of sound software engineering methodologies.
  • Demonstrated record in collaborative software development.
  • Working knowledge of control systems (EPICS preferred) and common techniques for automated data collection.


  • Occasional travel.
