Sr. DFT Engineer, SI Hardware

About the role

• Sr. DFT Engineer, SI Hardware | Tesla (Tesla SI)
• Location: Austin, Texas | Req ID: 250576 | Job Type: Full-time
• What to Expect

The Tesla SI Hardware team is at the forefront of revolutionizing artificial intelligence through cutting-edge hardware innovation. Comprising brilliant engineers and visionaries, the team designs and develops advanced SI inference chips tailored to accelerate Tesla’s machine learning capabilities.

A key part of this effort is Dojo, Tesla's custom supercomputer system built to efficiently train massive neural networks on vast video data from the fleet. The work of Tesla's SI Hardware team powers the neural networks behind Full Self-Driving (FSD), and Tesla humanoid robot, Optimus, pushing the boundaries of computational efficiency and performance.

By creating custom silicon and optimized architectures, the team ensures Tesla remains a leader in AI-driven automotive and energy solutions, shaping a future where intelligent machines enhance human life.

Tesla’s SI Hardware team is looking for a DFT Engineer to work on custom ASIC design-to-production. You will help drive the state-of-the-art in testability, debug and safety to achieve high test coverage, quality, and safety needed to aggressively deliver very low DPPM, while optimizing the test cost. We are open to hiring in Austin, TX; Palo Alto, CA.

What You'll Do

• Define and implement various DFT features at RTL and gates using in-house flows
• Work closely with the physical design team in achieving design closure with DFT features
• Perform block-level scan insertion, ATPG, coverage analysis, and simulations
• Run top-level test pattern retargeting and simulations
• Identify design changes needed for improving test coverage
• Work with test / product engineering team members on test pattern delivery and Si bring up

What You'll Bring

• Knowledge of Testability techniques and features (Compressed Scan, Built-in-Self-Test, Loop-Back, Boundary Scan) covering digital logic domain, embedded memories and PHY/IO’s
• Well versed in JTAG / 1500 / 1687 networks. BSDL, ICL and PDL knowledge preferable
• Expertise in ATPG, coverage analysis, and zero-delay / SDF-based pattern simulations. Experience with Cadence DFT tools (Modus and Genus) or Mentor DFT tools (Tessent Shell) preferred
• Good knowledge of Verilog, logic design, circuit design fundamentals as well as timing
• Working knowledge of TCL, python (or another scripting language like Perl)
• Experience in implementation of MBIST and knowledge of repair schemes, algorithms is a plus
• Experience or working knowledge of SERDES, Analog /mixed-signal DFT techniques (like IOBIST, loop-backs etc.) is a plus
• Post Silicon experience in Pattern conversion for Testers, Pattern Bring-up & Debug, Silicon Characterization etc. is a plus
• Degree in Computer Engineering or Electrical Engineering or equivalent experience with evidence of exceptional abilities
