## Description Xcimer Energy leverages decades of research in inertial fusion energy (IFE) combined with innovative engineering and manufacturing approaches. Our mission is to deploy fusion power plants at scale to meet global decarbonization goals. Xcimer has assembled a team of leaders across fusion science, materials, and manufacturing with a strong track record of execution. Backed by leading investors, Xcimer is uniquely positioned to deliver clean, reliable fusion energy.   This is a full-time, onsite role based at our headquarters in Denver, CO.   As a Coatings Materials Scientist in the Materials & Process Engineering (M&P) Department, you will work closely with the optical and laser systems teams to develop and implement advanced coatings and material solutions for fluorine-resistant environments. This role is hands-on and execution-driven, spanning coating development, materials characterization, and scale-up to production-relevant processes.   You will play a critical role in enabling durable optical performance and system reliability in aggressive chemical environments, directly impacting the core performance of Xcimer’s fusion systems. ## Responsibilities Develop and optimize fluorine-resistant optical coatings for laser-facing components, including mirrors, windows, and diagnostic optics. Design and evaluate fluorine-compatible material systems for broader system applications (e.g., chambers, fixtures, and exposed hardware). Work closely with the optics and laser engineering teams to define coating requirements, performance targets, and integration constraints. Lead hands-on coating deposition efforts, including thin film development, process tuning, and substrate preparation. Design and execute test plans and Design of Experiments (DOE) to evaluate coating adhesion, durability, chemical resistance, and optical performance. Perform detailed materials and coating characterization, including microstructural, compositional, and optical property analysis.
