System test and characterization engineer

• 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 as well as system performance measurements.
• Define and run link DOEs using uLED on ASIC transmitters, fiber bundle as transmission and PD on ASIC as receivers.
• Characterize various aspects of both existing and potential future optical components such as evaluating signal-to-noise ratio (SNR), receiver sensitivity, bit-error-rate (BER), crosstalk, power consumptions and link budget of the transmission system
• Work with PCBA design engineers to design, fabricate and bring up test boards. Experience in schematic capture, circuit simulation and PCB design guidance
