Your Mission
The future of AI computing is light, not electrons. Q.ANT is building photonic processing systems that compute with light - delivering a scalable, energy-efficient alternative to transistor-based architectures for next-generation AI and HPC applications.
As , you will provide technical leadership for the definition, integration, and bring-up of complete processor-based photonic systems. You'll oversee system-level electrical design - both digital and analog - ensuring performance and signal integrity at GHz frequencies, while coordinating activities across processor design, board/system hardware, firmware, and validation teams.

Why Q.ANT
Who we are and what we do:
Q.ANT is a photonic deep-tech scale-up developing photonic processing solutions that compute with light and deliver a scalable alternative to transistor-based systems.
Why now matters:
AI data centers are projected to consume 17% of US electricity by 2030. A single GPU now draws as much power as a kitchen oven. Traditional CMOS processors require 1,200 transistors for a simple 8-bit multiplication - Q.ANT's photonic chip does it with one optical element.
In July 2025, the Leibniz Supercomputing Centre became the world's first HPC facility to deploy photonic computing in production.This isn't research anymore - it's real, it's shipping, and it's redefining what's possible.
How to Apply
We're looking for someone who gets energized by the challenge of integrating cutting-edge photonics with high-speed digital systems - and who wants to see their work deployed in production systems that are already changing how the world computes.
