Job Description

The Lawrence Berkeley National Lab's () Advanced Light Source Division () Division has an opening for a Radiation Physicist . to join our team. In this pivotal role, you will conduct radiological risk assessments, perform radiation calculations, provide shielding requirements, oversee radiation safety protocols, and collaborate with engineers on shielding design. This position provides an opportunity to work with cutting-edge technology, contribute to groundbreaking research, and ensure the safety and success of a world-class scientific user facility.

The Advanced Light Source is a U.S. Department of Energy (DOE) Office of Science national scientific user facility whose excellent scientific reputation, expert staff, and capabilities in the soft x-ray, hard x-ray, and infrared regimes attract nearly 1,600 academic and industrial users each year in disciplines spanning physical, chemical, materials, biological, energy, and Earth sciences. It is one of five Berkeley Lab user facilities that serve a combined 11,000 users annually. The co-location of these user facilities - including the Molecular Foundry Nanoscale Science Research Center and the NERSC scientific computing center, as well as Berkeley Lab's outstanding programs in materials and chemical sciences, among others - offers a prime environment for collaborative science. The ALS has been a global leader in soft x-ray science for more than two decades and is currently undergoing a large-scale upgrade (ALS-U) that will endow the facility with state-of-the-art x-ray capabilities. It's an exciting time to join our growing team!
