Our focus on customer-driven product definition and commitment to design solutions in the cloud, for the cloud, results in breakthrough execution and scale for our customers. We are headquartered in the heart of California’s Silicon Valley, with R&D centers and offices in Taiwan, China, Vancouver and Toronto, Canada, and Haifa, Israel.

We are looking for Principal Design Verification Engineers with proven experience in working on industry standard protocols such as PCIe/CXL/DDR/Ethernet. Using your coding and protocol expertise, you will contribute to the functional verification of the designs from coming up with block level and system level verification plan to writing test sequences, test execution, collecting and closing coverage. 

Basic qualifications

  • Strong academic and technical background in electrical engineering. At minimum, a Bachelor’s in EE is required and Masters degree preferred.
  • ≥10 years’ experience supporting or developing complex SoC/silicon products for Server, Storage, and/or Networking applications.
  • Professional attitude with the ability to prioritize a dynamic list of multiple tasks, to plan and prepare for customer meetings in advance, and to work with minimal guidance and supervision.

  • Entrepreneurial, open-minded behavior and can-do attitude. Think and act fast with the customer in mind!
  • Authorized to work in the US and start immediately.

Required Experience

  • Experience with interpreting PCIe/CXL standard protocol specifications to come up with verification plan and execute them in simulation environments.
  • Must be able to work independently to develop test-plans, and related test-sequences in UVM to generate stimuli and work collaboratively with RTL designers to debug failures.
  • Develop user-controlled random constraints in transaction-based verification methodology. Experience writing assertions, cover properties and analyzing coverage data.
  • Must have prior experience using Verification IPs from 3rd party vendors for PCIe/CXL (with focus on Gen3 or above)
  • Develop VIP abstraction layers for sequences to simplify and scale verification deployments.
  • Currently based locally or open to relocation. 

Preferred Experience

  • Physical Layer, Link Layer and Transaction Layer verification expertise in PCIe /CXL protocol
  • Experience with compliance at the physical and transaction layers for PCIe/CXL endpoints or root ports.
  • Experience in analyzing performance metrics of CXL/PCIe
  • Experience in system level verification for PCIe/CXL


We know that creativity and innovation happen more often when teams include diverse ideas, backgrounds, and experiences, and we actively encourage everyone with relevant experience to apply, including people of color, LGBTQ+ and non-binary people, veterans, parents, and individuals with disabilities.
