HW Post-Silicone Validation Engineer

Join Cisco's Post-Silicon Validation Team, where a startup culture meets the resources of a leading networking company. Collaborate with engineers and designers to validate ASICs and shape the future of high-performance networking technology.

Responsibilities:

• Perform hands-on post-silicon electrical validation in lab environments for networking ASICs and evaluation platforms.
• Support early-silicon bring-up activities.
• Execute detailed hardware validation plans covering functionality characterization, performance, and reliability.
• Set up, configure, and maintain lab benches, boards, and test equipment.
• Assist with power-on, reset sequencing, clock bring-up, and strap configuration.
• Perform voltage, current, and signal integrity measurements.
• Capture and analyze waveforms, eye diagrams, jitter, PDN measurements, and error metrics.
• Help isolate silicon, board, or signal integrity issues under guidance.
• Validate Ethernet MAC/PHY and high-speed interfaces such as PCIe and SerDes.
• Assist with link training, lane margining, and BER testing.
• Support packet-level validation using traffic generators and protocol analyzers.
• Operate oscilloscopes, logic analyzers, VNAs, protocol analyzers, and multimeters.
• Use lab automation tools and scripts to control equipment and capture data.
• Use thermal chambers and chillers to perform temperature-related tests.
• Perform minor soldering re-work on test boards.
• Follow ESD, safety, and lab best practices at all times.

Qualifications:

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related field.
• Minimum 3 years of experience (internships, co-ops, or academic lab experience acceptable).
• Prior experience in electronics, digital logic, and signal integrity concepts.
• Experience in schematics/Layout files and understanding board-level designs.

Skills:

• Experience with silicon bring-up or hardware validation labs.
• Familiarity with DDR5, USB3.0, SGMII, PCIe Gen3.x, USB2.0, eMMC, SPI, MDIO, I2C, UART.
• Exposure to Ethernet, PCIe, or SerDes testing.
• Experience with high-speed measurement techniques (eye diagrams, BER, jitter).
• Lab automation experience (Python).
• Understanding of networking fundamentals and packet-based systems.
