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 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

Qualifications:

Expertise with optical transceiver circuits such as Trans-impedance Amplifier (TIA), laser/led drivers and photodetectors

Familiarity with datacenter class optical module designs for Quad Small Form-factor Pluggable Octal Small Form Factor Pluggable (QSFP)/(OSFP) form factor pluggable modules or emerging Near-Packaged Optics (NPO) or Co-Packaged Optics (CPO) approaches.

Familiarity with industry standards including IEEE Ethernet standards, OIF standards and MSAs

Preferrred Qualifications:

Ability to work cross-functionally with ASIC, packaging and optical design teams and provide clear technical inputs
Strong verbal and written communication skills, and ability to articulate and engage with both technical and non-technical stakeholders at all levels
Ability to code scripts in python for validation and data analysis
Working knowledge of high-speed test instruments such as VNAs, sampling and real time oscilloscopes and spectrum analyzers
Hands-on lab experience especially with probed/free space coupled (using stages) optical systems

System test and characterization engineer
