Job Description

Credo’s Optical Systems Applications Engineering group is seeking an Optical Systems Validation Engineer to validate Credo’s DSP devices with high-speed optical components for data rates ranging from 50 Gbps to 224 Gbps and beyond. As an Optical Systems Validation Engineer, you will design optical test hardware, create test procedures, and analyze test results to finalize chip and module configurations used across various applications, including AI and data center applications. As an essential team member, your contribution will be critical to Credo’s development of high-speed interconnect products for data center applications.  

Responsibilities

• Conduct electrical and optical measurements of optical evaluation boards and modules. 
• Design and analyze optical and high-speed electrical hardware for optical test stations. 
• Evaluate optical components (including, but not limited to, various types of lasers, modulators, and receivers) for performance and reliability in reference designs and for feasibility in test systems.
• Design and execute engineering validation testing and design validation testing.  
• Perform failure analysis. Work with contract manufacturers or field applications engineering teams when needed.  
• Work collaboratively across teams, including Signal Integrity, Thermal, Mechanical, Firmware, and Electrical Engineering. 

Minimum Qualifications

• B.S. (Electrical Engineering) with 7+ years of relevant experience or M.S. (Electrical Engineering) with 5+ years of relevant experience.
• Strong analog/digital/RF/Optical circuit analysis skills
• Strong background in circuit theory, linear system theory, feedback, ICs, high-speed RF fundamentals, and link budget analysis
• Strong laboratory measurement skills with high-speed optical and electrical test equipment
• Strong communication and presentation skills.

 Preferred Qualifications:

• Experience in optical alignment and fiber coupling.
• Strong experience with standard optical test instruments, such as power meters, optical spectrum analyzers, optical variable attenuators, and multi-axial stage positioners
• Strong experience in high-frequency electrical test equipment such as vector network analyzers, digital communication analyzers, spectrum analyzers,
• Good understanding of tolerances, yield analysis, reliability, and failure analysis variation.
• Experience in high-speed optical and electrical test and test automation.
• Programming skills in one or more of the following: Python, C/C++, MATLAB, or LabVIEW for collecting, analyzing, and presenting data
• Experience in Signal Integrity analysis of high-speed PCBs (Keysight ADS)
• Experience in mechanical CAD software (AutoCAD or equivalent)
• Experience in Electromagnetic analysis of optoelectronic assemblies (Ansys HFSS)
• Experience in PCB layout for high-speed
