Building the infrastructure for AGI
Flux designs and manufactures optical processors to train and run inference on large AI models.

What we're working on
The demand for AI will soon exceed our current computing capacity by a massive margin. Who can supply this much computing power is the trillion-dollar question. Relying solely on silicon chips could mean building entire nuclear facilities just to power millions of GPUs.
At Flux, we see a more promising way forward: optical computing. By offering higher performance and consuming far less energy, optical solutions move beyond the physical constraints of silicon. We’re confident this new paradigm will shape the future of AI.
Help us build the future of AI hardware
We reward innovation, speed, and bold thinking.
You’ll be based in our new office in the AI hub of Kings Cross.
