The Common Hardware Group (CHG) creates innovative hardware platforms central to the AI era, powering Cisco’s core Switching, Routing, and Wireless products for organizations globally. Our innovations in silicon, optics, and hardware platforms—like Silicon One—are shaping the technology industry.

The Transceiver Module Group (TMG) within CHG is a collaborative and multi-functional product development and sustaining team responsible for defining and implementing specifications, test procedures, and validation of optical interconnection technologies ranging from 100

Mbit/s to 1.6

Tbit/s. As optics are the critical backbone of AI infrastructure, our team is at the forefront of this evolution, ensuring the seamless integration of high-performance modules across a vast portfolio of Cisco switches and systems.

• Develop and implement comprehensive test and configuration strategies for new optical module transceiver products to ensure robust performance.
• Investigate complex technical issues by performing root cause analysis and implementing corrective actions for hardware-software interactions at the system level.
• Build and maintain automation tools and scripts (e.g., Python, LabVIEW, etc.) and leverage AI methodologies to enhance test efficiency and accelerate data analysis.
• Conduct lab operations using electrical and optical test equipment, including optical attenuators, switches, I2C analyzers, digital multi-meters, traffic generators, and oscilloscopes.
• Characterize module low-speed IO and electrical timing using knowledge of EEPROM programming, digital logic, and the Common Management Interface Specification (CMIS).
• Partner with multi-functional engineering teams and external suppliers to ensure high-quality product designs that meet industry standards and perform reliably across Cisco switches and systems.
• Author clear test reports and present complex technical data to multi-functional partners to facilitate informed decision-making.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or relevant field with 5+ years of relevant work experience or Master’s degree in Electrical or Computer Engineering with 3+ years of relevant experience.
• Experience with electrical/optical test and measurement equipment. Such as optical attenuators, switches, I2C analyzers, digital multi-meters, traffic generators, or oscilloscopes.
• Experience in automation environments (e.g., Unix/Linux, Python).
• Experience of digital logic, EEPROM, and I2C interfaces.

• Demonstrated familiarity with optical transceiver industry standards (SFF, IEEE) and MSA (Multi-Source Agreement) specifications.
• Strong understanding of CMIS (Common Management Interface Specification) standards.
• Experience with basic networking, including Cisco IOS/NXOS or CCNA certification.
• Demonstrated interest or experience in applying AI tools to enhance test automation and hardware validation processes.
