[HW] PHY Engineer

Frontier of On-device AI Semiconductors

for Everyone, Everywhere

About DeepX Co., Ltd.

DEEPX is a forward-thinking Series D startup architecting the infrastructure for the Physical AI era.

By delivering the world’s most energy-efficient NPU technology, we are solving the critical power and heat challenges of Generative AI to bring super-intelligence to every device, everywhere.

Our global leadership is validated by our record-breaking recognition as a multi-year CES Innovation Award honoree (2024 & 2026) and being named the 2024 Frost & Sullivan Company of the Year in the NPU sector. With an enterprise value approaching 1 trillion KRW, DEEPX offers a unique pre-IPO

opportunity to join a market leader defining the new industry standard for the $70B AI semiconductor market.

We are currently scaling toward mass production of our flagship DX-M1 (Samsung 5nm) with over 50 global projects scheduled, while engineering next-generation 2nm solutions to support 100B parameter Large Language Models (LLM) at the edge. ☞ Link
