Company

hirify.global provides semiconductor solutions that serve as essential building blocks for data infrastructure across enterprise, cloud, and AI architectures.

What you will do

• Perform hands-on DFT implementation, including MBIST, BISR, Boundary Scan (IEEE 1149.x), and IJTAG (IEEE 1687) insertion.
• Execute DFT verification, debug, and DRC closure using Siemens Tessent and SpyGlass DFT/RTL checks.
• Generate, simulate, and debug MBIST and logic ATPG patterns to drive test coverage closure.
• Develop and validate DFT timing constraints for scan, BIST, and test modes.
• Automate DFT insertion and analysis flows using TCL scripts.
• Collaborate with RTL, Physical Design, and ATE teams to support pre-silicon signoff and post-silicon pattern bring-up.

Requirements

• Bachelor's, Master's, or PhD in Computer Science, Electrical Engineering, or related fields.
• 5+ years of hands-on DFT implementation experience.
• Strong proficiency with Siemens Tessent (MBIST/BISR, Boundary Scan, IJTAG, ATPG).
• Strong TCL scripting skills for DFT automation.
• Experience with the full DFT lifecycle from RTL/netlist through silicon debug.
• Must be eligible to access export-controlled information as defined under U.S. export control laws.

Nice to have

• Experience in MBIST coverage improvement and repair efficiency optimization.
• Post-silicon experience including pattern bring-up, tester conversion, and silicon characterization.
• Exposure to mixed-signal or SERDES DFT, such as IOBIST or loopback testing.

Culture & Benefits

• Employee stock purchase plan with a 2-year look back.
• Comprehensive family support programs to balance work and home life.
• Robust mental and physical health resources.
• Recognition and service awards for contributions and milestones.
