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.

• 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.

• 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.

• 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).

• Competitive Compensation – A salary package aligned with industry standards and your experience.

• Equity Opportunities – Take part in our success with stock options.

• Flexible Work Environment – Enjoy working from our office or in a hybrid work setup with the flexibility to work remotely part of the week. We require a minimum of 3 days per week in our office to support collaboration and team culture. (LA Office only)

• Unlimited PTO – Take the time you need with our flexible, trust-based vacation policy, including paid holidays. We encourage everyone to rest, recharge, and take care of themselves.

• Health & Wellness – Comprehensive medical, dental, and vision coverage with 100% of the premium paid by the employer for employees.

• Cutting-Edge Tools – Get access to the latest hardware and software you need to do your best work.

• Mission-Driven Culture – Be part of a team working on meaningful challenges with real-world impact.

• Inclusive Team – We foster a supportive and diverse workplace where all voices are valued.
