The mission of this role is to develop and execute electrical validation tests to quantify parametric device performance and margins over all system conditions. The validation team holds customers' requirements in the highest regard and is solely responsible for certifying a product's parametric conformance to this high bar. At Astera Labs, we are looking for motivated Post-Silicon Validation Engineers to work on our game-changing portfolio of connectivity products for Artificial Intelligence and Machine Learning applications. In this role you will formulate a comprehensive post-Silicon validation plan, automate the testing of ICs and board products, design experiments to root-cause unexpected behavior, report results and specification compliance, and work with key internal customers to quantify margins and ensure robustness.

Key Responsibilities:

  • Develop and execute electrical validation tests to quantify parametric device performance and margins over all system conditions.
  • Formulate a comprehensive post-Silicon validation plan, automate the testing of ICs and board products, design experiments to root-cause unexpected behavior, report results and specification compliance, and work with key internal customers to quantify margins and ensure robustness.
  • Work with key internal customers to quantify margins and ensure robustness.
  • Design experiments to root-cause unexpected behavior.
  • Report results and specification compliance.
Requirements:
  • Strong academic and technical background in Electrical or Computer Engineering. At minimum, a Bachelor's is required, and a Master's is preferred.
  • ≥8 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 internal meetings in advance, and to work with minimal guidance and supervision.
  • Entrepreneurial, open-minded behavior and can-do attitude. Think and act with the customer in mind
  • Proven track record solving problems independently, preferably as a tech lead
Preferred Experience:
  • Experience leading SoC Debug and development for high-speed interfaces such as PCIe/802.3 Ethernet
  • Familiarity with PCIe or Ethernet especially Electrical Compliance sections
  • Working knowledge of key, high-speed design blocks such as PLL's, DFE, Tx EQ, PAM4
  • Experience in system testing, characterization, margin analysis and optimization of high-speed PCIe/CXL data links over long and short channels
  • Strong python scripting ability: knowledge of object-oriented programming and basic dev ops using git for source control and collaboration
  • Deep background in developing bench automation techniques, preferably using Python, with emphasis on execution efficiency, repeatability, and data analysis.
  • Proficiency using high-speed lab equipment such as BERT, Oscilloscope, and VNA
Base Pay Range:

The base pay range for this role is $160,000 - $240,000. Your base salary will be determined based on your location, experience, and the pay of employees in similar positions.

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.
