Company

hirify.global is a stealth-mode startup building foundational technology for performance, scalability, and resiliency in large-scale AI data center clusters.

What you will do

• Own schematic design for multi-phase buck regulators, point-of-load converters, and power sequencing circuitry.
• Select power components and define placement, routing, decoupling, and high-current power-path constraints.
• Collaborate with package engineering on power delivery at socket and package interfaces.
• Lead laboratory validation of VRM efficiency, loop stability, DC IR drop, thermal behavior, ripple, noise, and transient response.
• Characterize power rails with oscilloscopes, electronic loads, network analyzers, thermal cameras, and related equipment.
• Partner with SI/PI, package, hardware, firmware, and systems teams to debug power integrity issues across the complete platform.

Requirements

• Extensive experience designing high-current, multi-phase DC-DC regulators for ASICs, GPUs, processors, accelerators, or comparable compute platforms.
• Experience designing power hardware for systems with 500W+ devices or similar high-current requirements.
• Deep knowledge of board-level power delivery networks, decoupling, power sequencing, transient response, and voltage regulation.
• Hands-on experience with schematic capture and layout oversight for complex power delivery systems, preferably with Cadence Allegro or Concept.
• Strong laboratory validation skills and experience with SPICE-based time-domain circuit simulation or similar workflows.
• Ability to collaborate in a fast-moving engineering environment.

Nice to have

• Experience with power delivery for AI accelerators, GPUs, networking or switch ASICs, and high-performance server platforms.
• Knowledge of power integrity effects on SerDes, PCIe, Ethernet, CXL, or other sensitive high-speed interfaces.
• Experience validating systems under dynamic AI inference or high-utilization workloads.
• Exposure to package-level power delivery, socket interfaces, or board/package co-design.
• Experience automating laboratory validation with Python or similar scripting languages.

Culture & Benefits

• Work in a startup environment backed by top-tier venture capital firms and notable angel investors.
• Collaborate with experienced builders and operators with a strong emphasis on trust, integrity, respect, and shared responsibility.
• Receive meaningful equity, benefits, and a 401(k).
• Work across remote and on-site locations in the United States and Canada.
