Product Marketing Manager, Grenoble

We are a deep-tech startup developing heterogeneous integrated silicon photonics to enable the next generation of optical interconnects for AI factories and hyperscale infrastructure. Our technology combines advanced photonics and electronics to deliver scalable, high-bandwidth, and energy-efficient connectivity.We are building not just products—but a new category in how AI systems are interconnected. We are looking for a hands-on Product Marketing Manager who can bridge cutting-edge photonics technology with real market needs. This is not a “slides-only” role—you will be expected to dive deep into the technology, shape the narrative from first principles, and directly influence product direction and company strategy.You will define how our technology is understood by the market and help turn it into a product commercial success.
