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.

Responsibilities

• Set the vision and long-term direction for Compiler and Architecture organization - spanning all aspects of compiler development (frontend, middle-end, backend), and cycle-accurate performance modelling team -holding the organisation accountable for delivering against it.
• Build and lead a high-performing Compiler & Architecture organisation. Develop managers who take genuine ownership of customer outcomes and reliability, not just delivery metrics.
• Define what technical excellence looks like at scale. Establish the architectural principles, review cadences, and quality standards the organisation operates by,
• Shape the technical direction for ML inference on OLIX hardware, partnering closely with the ASIC and FPGA teams for hardware-software co-design - making hard calls on where to invest.
• Translate long-term business direction into clear priorities to maximize customer and business outcomes, and shutting down work that does not.
• Build a healthy, high-performance culture that balances innovation, speed, and operational excellence.
