"ARI Lead Beamline Scientist"

The National Synchrotron Light Source II (NSLS-II) at Brookhaven National Laboratory seeks a lead beamline scientist for the soft x-ray angle-resolved photoemission spectroscopy (ARPES) and resonant inelastic x-ray scattering (RIXS) Imaging (ARI) beamline. The ARI beamline incorporates two endstations, one for ARPES and one for RIXS, and provides ultra-high spatial resolution (~100nm) scanning imaging capability in each endstation via tightly-focusing mirror optics. Other spectroscopic techniques are also provided including XPS, XAS, inverse XAS, photoelectron diffraction, and fluorescence. The ARI beamline is currently under construction with expected first light in the summer of 2026.

As the Lead Beamline Scientist for ARI, 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 ARI user program and beamline operations. The Lead Beamline Scientist will develop a vision and strategy to advance the ARI user science program, enhance the beamline capabilities, and propose facility improvements and upgrades to ensure that the ARI beamline remains at the state-of-the-art.

Essential Duties and Responsibilities:

• Refine and evolve the mission and technical scope of the ARI beamline by interacting effectively with the scientific user community and with the Electronic Structure Techniques Program and NSLS-II colleagues.
• Grow the ARI beamline's scientific program in line with the NSLS-II strategic plan and support the facility mission with a focus on scanning imaging angle-resolved photoemission spectroscopy and resonant inelastic x-ray scattering.
• Lead the safe operation of the ARI beamline and provide oversight of staff and users working at the beamline.
• Supervise a team of beamline scientists assigned to the ARI beamline.
• Propose and manage the ARI 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 and/or technical research and development program that leverages or enhances the unique capabilities of the ARI beamline.
• Coordinate the ARI user program with those of other NSLS-II beamlines within and outside the Electronic Structure Techniques Program that offer complementary techniques or capabilities.

Required Knowledge, Skills, and Abilities:

• PhD. in Physics, Chemistry, Materials Science, or other relevant fields with at least 6 years' experience in synchrotron-based research with significant experience using electron spectroscopy and/or x-ray scattering techniques.
• Considerable knowledge of ARPES and RIXS fundamentals and data analysis.
• Familiarity with resonant inelastic x-ray scattering measurements and data analysis.
• Strong publication record using ARPES and/or RIXS 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:

• PhD. in Physics, Chemistry, Materials Science, or other relevant fields with at least 10 years' experience in synchrotron-based research with significant experience using electron spectroscopy and/or x-ray scattering techniques.
• At least 3 years demonstrated successful experience with synchrotron beamline operation and user support.
• Demonstrated success in the design, installation, and/or commissioning of a synchrotron radiation beamline.
• Working knowledge of soft x-ray optics, x-ray and electron detectors, and/or beamline control systems (e.g., EPICS).
• Recognized expertise in angle-resolved photoemission spectroscopy.
• Programming skills for data analysis and/or collection in Python.
• Demonstrated success supervising or leading scientific or technical groups or projects.
