Lead Optical Design & Test Engineer - Free Space Optical (FSO) Communication Systems

• Design and optimize optical systems (telescopes, relay optics, Tx/Rx paths, filters) using Zemax OpticStudio
• Perform optical tolerancing and thermal analysis to ensure manufacturability and alignment robustness
• Collaborate with opto-mechanical engineers to define interfaces and alignment concepts that maintain optical performance; support the design of opto-mechanics for demanding environmental conditions
• Develop practical alignment methods, including adjustment strategies, observables, and metrology selectio
• Design and implement optical test setups to measure beam quality, throughput, pointing accuracy, and wavefront performance.
• Create structured test procedures and verification processes suitable for qualification and production environments
• Create specification documents for the procurement of customized optical components. Accompany the procurement process, including the selection of international suppliers and supporting the incoming inspection
• Analyze system-level optical performance and support link-budget-driven design trades
• Support integration, troubleshooting, and validation during prototype and environmental testing

• Education: Master’s Degree or PhD in Optical Engineering or related fields
• 7-10 years of experience designing optical systems and practical laboratory validation
• Strong proficiency in Zemax (sequential & non-sequential) including tolerancing/thermal analysis; familiarity with other tools is a plus
• Hands-on experience aligning and testing precision optical systems
• Understanding of Gaussian beam propagation, laser optics, and alignment sensitivity
• Experience in developing repeatable optical test methods and documentation
• Ability to work cross-functionally with mechanical, systems, and test engineers
• Excellent English communication skills
