THE OPPORTUNITYLumai is redefining how the world computes. We are an ambitious, venture-backed UK startup building a breakthrough AI accelerator for the data centre, powered by 3D optical compute. Our technology uses light rather than electricity to perform the matrix multiplications at the heart of AI inference — at speeds and scales electronics cannot reach, and at a fraction of the energy.The performance and efficiency gains we are unlocking could reset the economics of AI infrastructure and change how intelligence scales globally.If you want to bring genuinely new technology to market and work at the edge of what is physically possible, Lumai is where you can do it.ABOUT LUMAIFounded in 2022, Lumai is a University of Oxford spinout using optical processing to accelerate large language models and other transformer-based AI systems. Our team brings together optical computing, machine learning, physics, and silicon expertise.We have raised over $15 million from leading deep-tech investors and government grants,



and we are scaling quickly to deploy the fastest optical compute available anywhere. Every day here is spent on technology that did not exist five years ago. You will not be maintaining legacy systems.THE ROLEEvery analog and mixed-signal design ultimately has to answer to silicon. As an Analog Test & Characterization Engineer at Lumai, you will bring our chips to life on the bench, bringing up new silicon, characterising analog and mixed-signal performance, and closing the loop between what was simulated and what silicon actually does.You will work hands-on with lab equipment and custom test setups to extract accurate performance data on data converters, bias/reference circuits, and clocking IP, then work with the design team to understand and explain any gaps between measurement and simulation.You will report to the Senior Analog/Mixed-Signal Design Lead and work closely with circuit designers, layout, and firmware/software engineers to support silicon bri
