Title: Technical Lead, Mixed Signal IC Lab Validation and Test Engineer

 Location: Allentown, PA

 Description:  Technical Leader for IC Lab Validation of high-speed serial transceivers and control circuits for Silicon Photonics applications

This is a high-visibility role in Cisco’s Silicon Photonics group. As a lead validation engineer you are expected in pre-silicon:

·         Participate in design reviews, review product design specifications and create test requirements for design teams.

·         Design and document test evaluation boards for silicon validation.

·         Capture PCB schematics and work with SI and layout engineers to optimize board designs for high-speed RF testing.

·         Have a good understanding of packages, connectors etc. and impact on board level SI. Identify critical PCB BOM components.

·         Identify and procure test equipment required for successful test and validation of high-speed circuits.

·         Generate software/firmware specifications for Cisco’s development teams.

·         Evaluate boards through TDR and VNA measurements.

·         Develop test plans and schedules for successful IC validation.


·         Lead lab validation effort for top level characterization

·         Ensure proper test coverage for analog and digital functional coverage

·         Carry out validation across all PVT corners

·         Review and present validation data

·         Collaborate with cross functional teams to assist with module and ATE level test debug and yield analysis

·         Mentor junior engineers and summer interns


Technical Knowledge and Skills:

·         Candidate must have excellent lab skills with familiarity with state-of-the-art high speed test/characterization equipment

·         Deep understanding of high-speed Ethernet based transceivers

·         Knowledge of digital communication transceivers using modulation schemes such as PAM, QPSK/QAM, error correction techniques

·         The candidate must be able to interpret IEEE 802.3 standards

·         Good understanding of analog circuits such as op-amps, reference sources, analog-to-digital converters, digital-to-analog converters, high-speed custom digital logic, CDR, VCO, phase detectors etc. Good understanding of jitter mechanisms

·         Some understanding of device physics and analog layout issues are required.

·         PCB schematic capture tools such as Allegro or similar CAD tools

·         Matlab, Python, Visual Basis/C experience is a plus

·         Some knowledge of optical interface testing would be an advantage


Education & Experience:

Skills & Qualifications: BSEE/MSEE required with 10+ years in high speed RF validation with at least 5+ years specializing in multi-gigabit rate transceivers.
