Cisco Signal Integrity Engineer 

United States, California, San Jose 

120077166

The application window is expected to close on: 1/27/25

Our devices are designed to be universally adaptable across service providers and web-scale markets, designed for fixed and modular platforms. Our devices deliver high speed without sacrificing programmability, buffering, power efficiency, scale, or feature flexibility.

You'll be part of our group driving our game-changing next-generation network devices built with Cisco Silicon One™.

Your Impact

You will be joining the SP platform Mechanical Thermal group in San Jose, CA, which is responsible for designing and developing complex electro-mechanical systems for a variety of networking products from fixed to centralized and distributed architectures with sizes ranging from 1U to 40U. You’ll work with Hardware Distinguished Engineers and Hardware Leads to architect and develop cooling solutions for next-generation high-performance routing platforms. In this role, you’ll tackle the challenges of high-power ASICs and high-density optical transceivers by investigating and implementing innovative, next-generation cooling.

High-Level Responsibilities:

• Design and develop thermal solutions (air-cooled or liquid-cooled) for systems with high-power ASICs and high-density optical transceivers.

• Develop detailed package, board, and system-level simulations using Computational Fluid Dynamic tools such as Flotherm or Icepak to simulate and analyze thermal solutions.

• Collaborate with Distinguished Engineers and HW leads on system architectures and cooling.

• Manage or perform thermal testing (including airflow, acoustic, thermocouple testing, modules, and/or platform level validations) to validate simulation models.

• Lead and mentor other thermal engineers in the group.

• Investigate and implement new innovative thermal technologies.

• Collaborate with mechanical engineers, and other cross-functional teams to identify risks, derive tradeoffs and deliver objective, data-driven solutions.

• Develop test plans and test reports and present simulation reports to the project team and management.

Who You’ll Work With

You will be working very closely with the rest of our Mechanical/Thermal group, which is a dedicated team with foundations of innovation, teamwork, open communication, and customer success. You’ll also work cross-functionally with Hardware Engineering, Product Management/Marketing, Product Operations, Global Supplier Management (GSM), External Vendors/Suppliers, Manufacturing Operations, and EMS/JDM partners.

Who You Are

Preferred Qualifications

• PhD in Mechanical, Thermal Engineering, or relevant degree and 5+ years of relevant experience.

• 5+ years of relevant experience in the thermal design of telecom, compute, or networking equipment.

• Experience in the use of Computational Fluid Dynamic analysis tools such as Flotherm or Icepak.

• Knowledge and experience with advanced air-cooling technologies (vapor chamber and remote heat sinks, thermal interface materials, fans/fan trays).

• Experience with designing liquid cooling and/or immersion cooling systems.

• Experience with performing other analysis such as Finite Element Analysis (FEA) and Data Center cooling simulations.

• Proficiency with 3D MCAD modeling tools such as PTC's Creo or NX.

• Knowledge of optical transceiver module types, form factors, and requirements.
