System Test and Characterization Engineer

Responsibilities

• Lead a team of engineers to characterize optical transmitters, optical receivers and link performance of highly parallel opto-electronic interfaces
• Develop and maintain optical transmission system testing bed for full characterization of optical components and modules
• Define and run link DOEs using uLED on ASIC transmitters, fiber bundle as transmission and PD on ASIC as receivers
• Characterize signal-to-noise ratio (SNR), receiver sensitivity, bit-error-rate (BER), crosstalk, power consumptions and link budget
• Work with PCBA design engineers to design, fabricate and bring up test boards

Requirements

• MS or PhD in electrical engineering or physics
• 3+ years of experience
• Expertise with optical transceiver circuits (TIA, laser/led drivers, photodetectors)
• Familiarity with datacenter class optical module designs (QSFP, OSFP, NPO, or CPO)
• Experience with optical transceiver test methodologies
• Familiarity with IEEE Ethernet standards, OIF standards and MSAs

Preferred Qualifications

• Ability to work cross-functionally with ASIC, packaging and optical design teams
• Python scripting for validation and data analysis
• Working knowledge of high-speed test instruments (VNAs, sampling/real time oscilloscopes, spectrum analyzers)
• Hands-on lab experience with probed/free space coupled optical systems
