- Translate product requirements into optical architectures and system-level specifications
- Perform optical modeling and simulation (e.g.,Zemax, Code V,LightTools)
- Drive tolerance analysis, error budgeting, and performance optimization
- Collaborate with mechanical, electrical, software, and manufacturing teams to ensure robust system integration
- Own system-level trade studies and design decisions balancing performance, cost, and manufacturability
- Guide prototyping, testing, and validation of optical systems
- Develop and execute test plans; analyze data and iterate designs accordingly
- Support transfer to manufacturing, including alignment strategies and yield improvement
- Troubleshoot complex optical/system-level issues in development and production
- Mentor junior engineers and contribute to technical leadership within the team
- Interface with external vendors and partners for components and subsystems
