Software Engineering Director - Compiler & Architecture

ABOUT OLIX

AI is growing faster than any technology in history and the explosion in demand has created a massive infrastructure gap; we can no longer build chips or power stations fast enough to keep up. The industry is still leaning on a ten-year-old hardware blueprint that has reached its limit. A new paradigm that is faster and more efficient will be the biggest economic opportunity of the next century and create the most important company of the next decade. OLIX is building this next paradigm; the Optical Tensor Processing Unit (OTPU) achieves performance and energy efficiency that is impossible to match from existing chips.

ROLE

As Engineering Director, Compiler & Architecture, you will lead the organization (scaling to 24 ICs and 4 Managers) responsible for continuing to refine our OTPU architecture and partnering with other teams to translate it into real, reliable, and repeatable performance gains for customers.

We are looking for a senior engineering leader to help shape where OLIX is going, not just how we get there. You bring deep technical judgment and a proven ability to build high-performing organizations that move with pace and conviction. You'll set the technical direction, define what matters and why, and create the conditions for outstanding engineers and engineering managers to do their best work.
