ROLE SUMMARY We are seeking a Senior Optical Engineer to lead the design, analysis, and optimization of advanced optical systems for both ground-based and space-based telescope platforms. This role will be responsible for translating system requirements into high-performance optical designs, driving architecture decisions, and ensuring optical performance from concept through integration and validation. The ideal candidate brings deep expertise in optical design along with hands-on experience building and testing precision optical systems in complex, multidisciplinary environments. RESPONSIBILITIES - Design and develop complex optical systems for telescopes, including reflective, refractive, and hybrid architectures. - Perform optical design, modeling, and optimization using tools such as Zemax, Code V, or equivalent. - Translate system-level requirements into optical prescriptions that meet performance targets for resolution, sensitivity, field of view, and aberration control. - Conduct tolerance analysis, stray light analysis, and ghosting analysis to ensure robust performance across manufacturing and environmental conditions. - Define optical budgets and error allocations, including wavefront error, alignment tolerances, and environmental effects. - Partner with mechanical and thermal teams to support STOP (Structural, Thermal, Optical Performance) analysis and ensure optical stability and alignment. - Drive optical architecture trade studies across performance, manufacturability, cost, and risk - Collaborate cross-functionally with mechanical, electrical, software, and systems engineering teams to integrate optical designs into full telescope systems. - Support optomechanical design efforts, including mounting strategies, alignment features, and thermal compensation approaches. - Lead optical testing and validation activities, including development of test plans, alignment procedures, and calibration methods. - Support integration and test campaigns, including lab validation, field testing, and environmental testing for space-based systems (e.g., thermal vacuum, vibration). - Analyze test data, troubleshoot performance issues, and perform root cause analysis across system components. - Mentor junior engineers and contribute to optical engineering standards, processes, and documentation. BASIC QUALIFICATIONS - Bachelor’s or Master’s Optical Engineering, Physics, or a related field. - 5+ years of experience in optical design and analysis, ideally within astronomical instrumentation, imaging systems, or aerospace/defense. - Deep expertise in optical design tools such as Zemax OpticStudio, Code V, or equivalent. - Strong foundation in geometrical optics, physical optics, aberration theory, and diffraction-limited system design. - Experience with tolerance analysis, stray light analysis, and optical performance budgeting. - Familiarity with optomechanical design principles and constraints. - Knowledge of optical coatings, materials, and environmental effects on optical performance. - Strong problem-solving skills and ability to operate in a fast-paced, multidisciplinary environment. - Excellent communication skills and ability to lead technical discussions and design reviews. PREFERRED QUALIFICATIONS - Experience supporting or collaborating on STOP analysis. - Hands-on experience with optical alignment, interferometry, and optical test equipment. - Experience with reflective telescope designs (e.g., Cassegrain, Ritchey-Chrétien) and/or wide-field imaging systems. - Experience with space-based optical systems and environmental qualification (thermal, vibration, vacuum).
