Company

hirify.global builds hardware and software infrastructure for frontier AI inference, including custom chips, racks, and manufacturing systems.

What you will do

• Own daily monitoring of wafer, CoWoS assembly, and final test yield across NPI, production ramp, and high-volume manufacturing.
• Define, track, and communicate manufacturing KPIs, including yield, ramp velocity, cycle-time impact, excursion response, and corrective-action closure.
• Analyze wafer maps, parametric data, sort and final test results, assembly yield, and manufacturing history to identify yield-loss mechanisms.
• Lead cross-functional yield reviews and coordinate containment, material disposition, recovery, root-cause resolution, and corrective actions.
• Act as the operational interface with foundry, OSAT, CoWoS, and test partners on yield performance and improvement planning.
• Build automated yield dashboards, production reports, early-warning indicators, operating procedures, and standardized review workflows.

Requirements

• 7+ years of experience in semiconductor yield, product, or manufacturing engineering, or silicon operations, including production ramp or high-volume manufacturing ownership.
• Deep understanding of semiconductor manufacturing from wafer fabrication through wafer sort, advanced packaging, and final test.
• Experience managing yield performance with leading-edge foundry and OSAT partners and resolving complex yield excursions.
• Strong knowledge of statistical yield analysis, SPC, Pareto analysis, hypothesis testing, DOE, process capability, and root-cause analysis.
• Experience analyzing wafer maps, parametric and test data, bin distributions, assembly data, and equipment or process history.
• Bachelor’s degree in Electrical Engineering, Materials Science, Chemical Engineering, Physics, Mechanical Engineering, or a related technical field; ability to travel to partner sites as needed.

Nice to have

• Experience with 2.5D/3D integration or CoWoS.
• Advanced technical degree.
• Proficiency with SQL and Python or another scripting and analytics language.
