What you'll do:

You will be a technical leader in the Component Quality and Technology team within Supply Chain Operations, who will partner with Cisco’s IC design engineers in the Transceiver Module Group, silicon fabs, test equipment vendors and other Cisco Supply Chain teams to develop leading edge characterization and production test solutions on Cisco’s suite of silicon photonic integrated circuits.

You have expert knowledge in the design and measurement of OWAT (optical wafer acceptance test) and EWAT (electrical wafer acceptance test) structures and parameters that need to be tested to verify known good silicon. You will produce optical and electrical test parameter specifications based on prototype data collection and analysis of the tested structures.  You will specify and write test programs to capture this data, and automate the data analysis.

 

You have excellent knowledge of test equipment integration, and are able to write libraries to support the automated test of the integrations. You will have hands on experience in optical wafer level probing including integration and alignment of optical and electrical probes to perform the test measurement capabilities. You have knowledge in optical waveguide and test structure design, DFT, coupling structure design and optical measurements of waveguides and other optical structures.

 

Your scope includes defining characterization plans and generate characterization reports, defining production screening guard-band specifications based upon design intent and characterization results, and transferring new products into full manufacturing release by collaborating with offshore manufacturing personnel. You should also have the capability to write or revise test programs on 93000 test platform and other platforms as needed. Your additional responsibilities include manufacturing sustaining support on Cisco’s photonics integrated circuits.

 

You must have proven ability to perform statistical data/yield/correlation analysis on large data sets from wafer sort to system final test to find yield issues and apply root cause corrective actions to design and test teams. Your role will also be to drive component failure analysis at the die or module, containments, and root cause corrective actions interfacing with development/manufacturing engineering and management to resolve complex technical problems.

 

Who you'll work with:

You will be part of a team providing innovative opto-electrical test solutions for Silicon Photonics platform at Cisco. You will collaborate with and lead test implementation at optical wafer fabs and OSATs (out-sourced assembly and testing). You will liaise with IC design teams to ensure suitable test structures are incorporated in the designs to verify production silicon. You will further collaborate with IC designers, module and system hardware teams on integrated circuit verification and performance, and identifying and implementing corrective action on both new and mature products and technologies.

 

 

Who you are:

·       MS (or higher) in Physic, Optics, Electrical Engineering or related fields.

·       7+ years’ experience in optical testing and silicon IC bring-up, production and characterization test experience.

·       Deep knowledge in Optical signal characterization and testing using optical measurement instrumentation.

·       Experience programming in C, C++, Python, AWK, SED, Perl languages, Unix.

·       Strong working knowledge of integrating optical test equipment and writing instrument drivers to form a holistic solution.

·       Understanding of optical test structure design for testing and state of the art electro-optical testing and probing equipments.

·       Strong working knowledge of production ATE for characterization and production testing, and ability to automate data collection and analysis.

·       Deep knowledge on performing statistical data analysis, experience in yield management of high volume products (e.g., able to take STDF data and produce comprehensive data analytical charts for debug and yield improvement) and the ability to setup design of experiments to drive to the root cause of the problem.

·       Ability to drive deep collaboration and leadership across many parts of Cisco's technical entities to provide bleeding-edge solutions for Cisco's photonic and system test strategies.

·       Strong teamwork & collaboration skills. Excellent problem solving & effective conflict resolution skills.

·       An effective cross-functional communicator with strong, presentation and interpersonal skills, who perseveres and has cross-functional leadership to drive results and change across organizations up to the executive level.

·       Can communicate effectively with internal and external executives via executive summaries and project status overviews

·       Ability to thrive in a dynamic environment.

High level of motivation and energy.
