Company

hirify.global is a fabless semiconductor startup developing energy-efficient processors for edge computing, embedded AI, and high-performance applications.

What you will do

• Define DFT strategies and generate, validate, and deliver ATPG patterns for scan, MBIST, JTAG, and embedded memory testing.
• Develop and debug STIL and PDL test programs on Advantest and Teradyne ATE platforms.
• Support first-silicon bringup, load-board validation, and characterization across voltage, temperature, and frequency corners.
• Define and manage wafer probe, final test, and bin-sort flows, including power sequencing and test-time optimization.
• Coordinate test-program handoffs, pattern delivery, qualification, and acceptance criteria with foundries, OSATs, test houses, and design partners.
• Track probe and final-test yield data, resolve anomalies, and coordinate test capacity planning and lot scheduling.

Requirements

• 5+ years of semiconductor test engineering experience in a fabless or IDM environment.
• Hands-on experience with DFT, including scan insertion, ATPG, MBIST, and JTAG boundary scan.
• Experience generating and validating STIL patterns and managing test-pattern delivery packages.
• ATE test-program development experience on Advantest or Teradyne platforms, including wafer probe, final test, and load-board bringup.
• Ability to coordinate directly with external design partners and OSAT suppliers across multiple time zones.
• Strong written and verbal communication skills.

Nice to have

• Embedded memory characterization and programming experience, including non-volatile memory technologies.
• Experience with high-speed serial interface testing, major EDA DFT tools, or processes at 28nm and below.
• ATE yield analysis, test-time optimization, or test automation using Python or Perl.
• Experience generating VCD from RTL simulation and porting it to STIL.

Culture & Benefits

• Competitive compensation with meaningful equity.
• 401(k) matching and company-paid benefits.
• Paid parental leave.
• Flexibility and support for personal and professional development.
