Senior CPU DFT Engineer – Scan & MBIST

Job Description

We're seeking a DFT Engineer to join our CPU design team, focusing on Scan insertion, MBIST, and DFT infrastructure for complex, high-performance CPU cores. You'll be involved from architecture through silicon bring-up, contributing to world-class chip quality and manufacturability.

Responsibilities

• Deliver DFT implementation for CPU cores with an emphasis on scan insertion, test point insertion, and MBIST generation.
• Collaborate closely with RTL, verification, and physical design teams to ensure seamless integration of DFT structures.
• Develop and maintain DFT automation flows using industry-standard EDA tools.
• Analyze and optimize scan coverage, ATPG efficiency, and test time.
• Own DFT-related signoff (coverage analysis, timing, pattern validation).
• Support silicon bring-up and yield debug, partnering with ATE and product engineering teams.
• Contribute to development and continuous improvement of AheadComputing’s DFT methodologies.

Qualifications & Skills:​

• Minimum Qualifications:​​
  • B.S./M.S. in Electrical Engineering, Computer Engineering, or equivalent.
  • 6+ years of experience in DFT for CPU or complex SoC designs.
  • Experience in scan insertion, ATPG, and MBIST.
  • Hands-on experience with tools like Synopsys TestMAX, Mentor Tessent, Cadence Modus, or similar.
  • Strong scripting skills in TCL, Python, or Perl.
  • Solid understanding of logic design, synthesis, STA, and physical design impacts of DFT.
  • Experience with DFT timing constraints and integration into hierarchical flows.

• Preferred Qualifications:​
  • Experience with DFT for custom CPU pipelines or high-frequency logic.
  • Expertise in scan or memory test methodologies.
  • Exposure to DFT-related silicon debug and ATE bring-up.
  • Contributions to DFT methodologies or flow automation in multi-site teams.

What We Offer:

• Competitive salary and benefits package.
• Opportunities for professional growth in an innovative startup environment.
• Collaboration with talented engineers passionate about cutting-edge CPU technologies.
• A flexible and inclusive work culture based in Portland, OR or Austin, TX.
