Location: On-site in Austin, Texas, US or Bristol, UK

Salary: Starting from $321,000 in Austin or £220,000 in Bristol, plus equity.

Company

hirify.global develops the DX-1 decode accelerator, a rack-scale AI hardware platform combining digital logic, data movement, packaging, optics, and interconnect.

What you will do

• Architect and own DFT strategies for complex, high-throughput digital pipelines in advanced CMOS nodes.
• Implement and verify Scan, JTAG, Boundary Scan, Memory BIST, and related DFT features.
• Develop and optimize ATE-compatible ATPG patterns to improve fault coverage and manufacturing yield.
• Develop DFT-focused RTL and collaborate on formal and constrained-random verification.
• Minimize DFT impact on power, performance, and area while defining interfaces with mixed-signal and software teams.
• Lead design reviews, mentor engineers, and drive testability and silicon debug practices through the ASIC lifecycle.

Requirements

• 7+ years of hands-on DFT architecture, implementation, and verification for high-performance ASICs or SoCs, including ownership of at least one product with comprehensive DFT coverage.
• Experience with Scan/ATPG, Boundary Scan, Memory BIST/Repair, compression, EDT, JTAG, IEEE 1149.1, and IEEE 1687.
• Expertise in scan insertion, pattern simulation, fault modeling, diagnosis, and large pattern-set management.
• Proficiency with Python and Tcl scripting for DFT automation, pattern management, and silicon debug.
• Experience with tape-out at 22 nm or below, plus knowledge of semiconductor device physics, fault models, and yield enhancement.
• Eligibility is subject to U.S. export control regulations and recent citizenship or permanent residency status; applicants from certain restricted countries may not be eligible.

Nice to have

• Knowledge of high-speed SerDes or HBM/DDR DFT challenges.
• Familiarity with AI/ML workloads or systolic arrays and their DFT implications.
• Contributions to open-source DFT tools or verification frameworks.

Culture & Benefits

• Meaningful stock options and ownership in the company.
• Annual Living-Local Bonus for residing within 20 minutes of the office.
• Employer-contributed retirement plans.
• Competitive compensation based on experience, skills, and location.
