Job description

About Voltai

Voltai is developing world models, and agents to learn, evaluate, plan, experiment, and interact with the physical world. We are starting out with understanding and building hardware; electronics systems and semiconductors where AI can design and create beyond human cognitive limits.

About the Team

Backed by Silicon Valley’s top investors, Stanford University, and CEOs/Presidents of Google, AMD, Broadcom, Marvell, etc. We are a team of previous Stanford professors, SAIL researchers, Olympiad medalists (IPhO, IOI, etc.), CTOs of Synopsys & GlobalFoundries, Head of Sales & CRO of Cadence, former US Secretary of Defense, National Security Advisor, and Senior Foreign-Policy Advisor to four US presidents.

About this Role

You’ll design and optimize power conversion and distribution systems for high-performance computing and autonomous hardware. You’ll architect topologies, simulate efficiency trade-offs, and validate thermal and EMI performance across extreme conditions. Your work will enable AI systems to operate with maximum power integrity and minimal loss.

Qualifications

You might thrive if you have 5+ years of experience in:

• Switch-mode power supply design, buck/boost converters, and GaN/FET topologies
• SPICE, PLECS, or other circuit-level simulation tools
• Power integrity, thermal management, and PCB layout for power systems
• EMI/EMC design, loop compensation, and hardware validation
