Company

hirify.global develops computing products and hardware platforms, including next-generation GPUs and AI accelerators.

What you will do

• Design and develop end-to-end power delivery solutions, including power conversion, management, sequencing, decoupling, and PCB/package optimization.
• Build and correlate VRM-to-die power delivery network models and perform DC IR-drop, AC target-impedance, transient droop, and Ldi/dt analyses.
• Architect debug and testability features such as voltage and current sensing, telemetry, rail isolation, enable control, and voltage margining.
• Design configurable power delivery solutions supporting multiple SKUs and derivatives from a single board.
• Create and execute validation plans, correlate bench and VR measurements with simulations, and improve model accuracy.
• Investigate power delivery failures, implement corrective actions, and collaborate with silicon, platform, board, software/firmware, and systems validation teams.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering or a related field.
• 5+ years of experience designing low-voltage, high-current, multi-phase DC-DC switching regulators, including buck and boost topologies, transient response, and conversion efficiency optimization.
• 5+ years of experience with signal integrity, power integrity, and power delivery network simulation tools such as Cadence Sigrity PowerDC/PowerSI and Ansys SIwave.
• 5+ years of experience developing power delivery simulation models using SPICE and time-based simulation tools such as LTSpice and SIMPLIS based on SoC power requirements.
• 5+ years of experience modeling power delivery networks across die, package, and PCB, including stackup, plane assignment, decoupling network design, and S-parameter extraction and correlation.
• 5+ years of experience using oscilloscopes and data acquisition systems for hardware troubleshooting and debugging.
• Experience collaborating with signal integrity, layout, and mechanical engineers, with working knowledge of SI/PI, PCB layout, and mechanical board design aspects.
