Responsibilities

• Perform precision optical alignment and fiber coupling of lasers, photodiodes (PDs), photonic integrated circuits (PICs), and waveguide-based devices.
• Build and characterize optical assemblies for TIA and driver validation, including optical-to-electrical (OE) and electrical-to-optical (EO) conversion testing; design, assemble, and maintain optical test stations and experimental setups for device characterization.
• Develop test procedures, automate measurements, collect data, and generate technical reports.
• Conduct high-speed optical and electrical measurements to evaluate device performance, reliability, and yield; analyze results, troubleshoot issues, perform root cause investigations, and recommend design and process improvements.
• Collaborate with optical, electrical, mechanical, and manufacturing engineers to support product development and qualification activities, following laser safety procedures and laboratory best practices.

Requirements

Basic Qualifications

• Master’s degree in Optical Engineering, Electrical Engineering, Applied Physics, or a related field, or a relevant bachelor’s degree plus at least two years of professional experience.
• Experience testing microelectronic systems and components, such as operational amplifiers, ADCs, DACs, and PLLs.
• Experience with common optical and electrical test equipment, including optical power meters, oscilloscopes, optical or electrical spectrum analyzers (OSA), variable optical attenuators (VOA), and multi-axis alignment stages.
