Senior Optical Engineer
Apply on Muonspace’s site →About the role Muon seeks a Senior Optical Engineer to join our team developing infrared remote sensing instruments. You will own stray light control and analysis by defining precise requirements for optical components and surface treatments, and optimizing optical transmission via custom coatings and filter components. Because this role spans a unique intersection of specialties—rigorous stray light analysis, custom coating specification, and spectral filter development—we welcome candidates who bring deep expertise in a subset of these areas and possess the strong foundational engineering skills and appetite to grow into the others. In this role, you will drive both the analytical modeling of stray light and the hands-on R&D efforts to specify, procure, and validate complex thin-film coatings and optical filters. Previous experience in non-sequential ray tracing, thin-film design, or vendor technical management in a fast-paced environment is required. Responsibilities Perform comprehensive stray light analysis using FRED to quantify and mitigate out-of-field stray light, scatter, ghosting, and thermal self-emission across complex infrared optical assemblies. Specify and analyze custom optical coatings and surface treatments to maximize transmission/reflectance and manage environmental durability for our multispectral IR instruments. Serve as the primary technical liaison with specialized optical component vendors.
