AIxic Labs · Stealth · Taiwan & US

Designing HPC silicon
at the frontier.

A small, senior team. An ambitious chip-design program. We are hiring across hardware, software, and architecture.

About

A senior team building HPC silicon.

AIxic Labs is a stealth chip-design company in Taiwan and the US, building custom HPC ASICs grounded in a substantial body of architecture and systems research. We work end-to-end across architecture, RTL, verification, and the software stack.

We hire people who want to take a chip from a clean sheet to a customer's rack — and own every layer in between.

We need engineers who are hands-on and who have mastered AI as a force-multiplier for their own productivity. We move fast because every person on the team ships.

Product details are available under NDA.
