**Primary Responsibilities**

- System Design & Testing: Lead the test setup design, alignment, and testing of complex optical systems in a laboratory environment, focusing on free-space and fiber-coupled architectures.

- Laser Operations: Directly manage and operate Class 3b and 4 laser systems, spanning both visible and Infrared (IR) wavelengths, ensuring all experiments comply with rigorous laser safety standards.

- Radiometric Analysis: Perform detailed radiometric analysis and measurements to characterize optical power, irradiance, and radiance across various system apertures.

- Instrumentation & Electronics: Set up, calibrate, and operate laboratory instrumentation and electronics to drive and monitor optical components, including laser controllers, TECs, and detector bias circuits.

- Automation: Develop and maintain test automation scripts to control laboratory hardware and streamline data collection processes.

- Detector Integration: Integrate and characterize highly sensitive detector technologies, including Avalanche Photodiodes (APD), Geiger-mode APDs (GmAPD), and Single Photon Counting Detectors (SPCDs) as well as IR and visible focal planes.

- Customer Interaction: Interface directly with customers to provide technical updates, present design reviews, and translate mission requirements into hardware specifications.

- Documentation: Author comprehensive technical reports, test plans, and data analysis summaries for internal stakeholders and external customers.

- Cleanliness Standards: Maintain hardware integrity by working within controlled environments, ensuring all optical assembly and testing meet strict cleanliness standards.
