Job Description

Experimental Physicist - Optical Imaging and Spectroscopy Denver, COScience – Laser Experimental Science /Full-Time /On-Site APPLY FOR THIS JOB Xcimer Energy leverages decades of research on Inertial Fusion Energy (IFE) combined with groundbreaking new laser architecture. Our mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. Xcimer has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by leading investors, Xcimer is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. Join us in powering a better world with inertial fusion! As an Experimental Physicist in the fields of optical imaging and spectroscopy, you will be collaborating with a team of engineers and scientists on identifying physics problems and risks associated with building high energy pulsed laser systems, proposing experiments, and designing, building, and operating advanced imaging and spectroscopic experiments in the fields of pulsed plasma imaging, high speed imaging, spectroscopy of atoms and molecules, and other similar fields. You will train technicians and junior science team members to conduct experiments in the long run. You will independently own and lead projects, coordinate with the architecture, science, and engineering teams periodically and adjust priorities and the course of these projects. You will also process and interpret experimental data and collaborate with the theoretical team to support the development of models of various processes. To succeed in this role, you will need a strong practical understanding of spectroscopic and imaging techniques for investigating fast processes (nanosecond timescales and longer). Demonstrated experience working with a wide range of diagnostic equipment is required. Experience building and working with vacuum systems in an experimental environment is expected. Experience with standard spectral and image analysis techniques for quantitative data interpretation. Experience using pulsed laser systems for excitation of gases or illumination of objects for fast imaging is highly desirable. It is expected that you will be able to accept responsibility for multiple small-scale projects immediately, learn quickly, and lead these projects effectively. You must be highly motivated, eager to learn, and possess excellent communication and organizational skills. Responsibilities Design, procure, build, and operate experimental setups and imaging systems. Own and manage schedule and budget. Collaborate with vendors to refine specifications and procure optical, vacuum, and diagnostic equipment. Develop clear procedures and documentation for technicians. Plan, execute, and oversee spectroscopic experiments, ensuring accurate data collection and thorough analysis. Calibrate devices and ensure experimental data are acquired accurately and free of artifacts. Work with the theoretical team on simulations and development of physics models Learn, understand, and actively participate in discussions related to future, larger-scale experiments. Troubleshoot and resolve non-trivial diagnostic, instrumentation, and system level issues Produce written technical reports and contribute to internal design reviews and technical discussions Qualifications M.S. degree with 3–4 years of relevant laboratory experience; Ph.D. preferred. Strong practical understanding of optical imaging and spectroscopic techniques Ability to own, operate, and maintain complex experimental systems. Demonstrated experience working with a wide range of experimental diagnostic equipment. Experience with techniques for quantitative imaging of turbulent flows, such as digital holography, is highly desirable. Proven ability to independently troubleshoot and resolve non-trivial technical issues. Experience planning, managing, and executing experiments. Strong data analysis skills Experience working effectively ... (truncated, view full listing at source)
