DFT Engineer

About the Role:

Tesla's Silicon Development Group is seeking a DFT Engineer to drive Design-for-Test across the design-to-production lifecycle for custom ASICs. In this role, you will own testability from design through silicon bring-up and high-volume manufacturing. You will advance state-of-the-art methodologies in test, debug, and safety to achieve high coverage, exceptional quality, and ultra-low DPPM—while optimizing test cost at scale.

Responsibilities:

• Define and implement DFT features at RTL and gate levels using in-house flows
• Partner with physical design teams to achieve timing and design closure with DFT constraints
• Execute block-level scan insertion, ATPG, coverage analysis, and simulations
• Perform full-chip pattern retargeting, validation, and sign-off
• Drive design improvements to enhance test coverage and diagnosability
• Collaborate with test and product engineering on pattern delivery, silicon bring-up, debug, and characterization

Requirements:

• Strong understanding of DFT methodologies including compressed scan, MBIST, loopback, and boundary scan across digital logic, embedded memory, and IO/PHY domains
• Solid knowledge of JTAG, IEEE 1500, and IEEE 1687; familiarity with BSDL, ICL, and PDL is a plus
• Proven expertise in ATPG, coverage analysis, and both zero-delay and SDF-based simulations
• Experience with industry-standard DFT tools such as Cadence Modus/Genus or Siemens Tessent
• Strong foundation in Verilog, digital logic design, circuit fundamentals, and timing analysis
• Proficiency in scripting (TCL, Python, or Perl)
• Experience with MBIST implementation, repair algorithms, and memory test strategies is a plus
• Exposure to SerDes and mixed-signal DFT techniques (e.g., IOBIST, loopbacks) is a plus
• Post-silicon experience including pattern conversion, bring-up, debug, and characterization is a plus
• Bachelor's or Master's degree in Electrical or Computer Engineering (or equivalent experience)
