Location: Los Alamos, NM
Cap-Exempt H-1B Position — No lottery required
**What You Will Do** The Accelerator Operations and Technology Division (AOT), Radio Frequency Engineering (RFE) group is seeking an R&D Engineer at either a Level 2 or Level 3 to join the Low-Level Radio Frequency (LLRF) team. The AOT division is responsible for maintaining, operating, and upgrading all accelerator systems at the Los Alamos Neutron Science Center (LANSCE) complex. These systems include two 750-keV Cockcroft-Walton-based injector systems (H+ and H- systems), a 201.25-MHz drift-tube linear accelerator (LINAC) utilizing high-power diacrode tubes, an 805-MHz coupled cavity LINAC utilizing high-power klystrons, a proton storage ring, and approximately one kilometer of beam transport lines that deliver beam to the five independent research programs. The RFE group oversees all radio frequency (RF) systems and consists of three specialized teams: Low-Level RF (LLRF) focused on real-time phase and amplitude controls; High-Power RF (HPRF) systems at 201 MHz; and High-Power RF systems at 805 MHz. The group provides expertise, support, technical, leadership and engineering support in RF system design, including gridded tube amplifiers, klystrons, RF control systems, and accelerator cavities. While the group's primary focus is the design, and implementation of RF systems for the LANSCE User Facility, it also supports a wide range of internal and external collaborations, sharing expertise with national security projects and international accelerator research communities. RFE team members frequently participate in global partnerships, workshops, and conferences to advance RF technology. **This position will be filled at either the R&D Engineer 2 or R&D Engineer 3 level, depending on the skills of the selected candidate. Additional job responsibilities (outlined below) will be assigned if the candidate is hired at the higher level.** **R&D Engineer 2 $106,400 - $176,000** The Low-Level Radio Frequency (LLRF) team at LANSCE is looking for a candidate with a backgro
