DFT - Staff DFT Engineer

Location: Bay Area, United States; on-site

Company

hirify.global is an early-stage chiplet startup developing technologies for high-volume, high-performance chiplet-based systems.

What you will do

• Define DFT strategy, methodologies, and implementation plans for chip-level designs and standalone IP blocks such as PHYs and chiplets.
• Implement DFT features in RTL for digital and analog blocks.
• Generate and validate 1687 PLD, 1149.x, MBIST, ATPG, SA, and TDF patterns at RTL and gate level.
• Collaborate with AMS and circuit architecture teams on high-speed interface coverage, structural tests, PRBS-based PHY loopback, and clock-network measurement.
• Automate DFT flows with scripting and support device bring-up, ATE pattern handoff, qualification, and RMA analysis.
• Document test coverage and mitigation strategies for coverage gaps.

Requirements

• Proficiency in modern DFT/DFx techniques and tools, including scan insertion, ATPG, and MBIST.
• Working knowledge of IEEE 1149.x, 1687, 1500, and 1838 standards.
• Proficiency in Verilog simulation and debugging of DFT structures at RTL and gate level.
• Experience taping out at least four designs and bringing up at least two designs on ATE or in a lab.
• Proficiency in TCL and shell scripting, plus working knowledge of Perl, Python, or a similar language and industry-standard development tools.
• BS in Electrical Engineering or equivalent and 6–9 years of experience; collaborative cross-functional work is required.

Nice to have

• Deep expertise in modern test methods, DFx methodologies, and test time, PPA, and coverage tradeoffs.
• Experience analyzing holistic device test coverage, including non-structural tests.
• Experience delivering hard and soft IP and creating design-kit collateral.
• 3+ years of experience with the Siemens Tessent platform, including ATPG, MBIST, iJTAG, BS, and SSN flows.
• MS or PhD in Electrical Engineering or equivalent.

Culture & Benefits

• Fast-paced early-stage startup environment.
• Cross-functional collaboration with experienced chip and circuit specialists.
• Work focused on manufacturable, high-performance chiplet technologies.
• Fun work environment with excellent benefits.
• AI tools may assist with parts of the hiring process, while final decisions remain with human reviewers.
