THE OPPORTUNITY
Lumai is redefining how the world computes. We are an ambitious, venture-backed UK startup pioneering a breakthrough AI accelerator for data centres which uses 3D optical compute. Our radical technology uses light to perform computation at orders of magnitude faster speeds and at far greater scales than ever before, all whilst consuming far less energy than traditional approaches.
Lumai is unlocking performance and efficiency gains that could transform the economics of AI and compute infrastructure and reshape how intelligence scales globally.
If you are passionate about bringing groundbreaking technology to market, and want to be part of a team pushing the boundaries of what is physically possible, Lumai is where you can make it happen.
ABOUT LUMAI
Founded in 2022, Lumai is a University of Oxford spinout using optical processing to accelerate large language models (LLMs) and other transformer-based AI systems. The team combines expertise in optical computing, machine learning, and physics.
Lumai has already secured over $15 million in investment from leading deep-tech investors including Constructor Capital, IP Group and PhotonVentures, alongside government grants, and is scaling rapidly to deploy the fastest optical compute currently available globally.
THE ROLE
In analog design, layout isn't an afterthought – it's where matching, parasitics, and noise coupling either preserve a carefully designed circuit's performance or quietly destroy it. As a Senior Analog Layout Engineer at Lumai, you will own the physical implementation of our custom analog and mixed-signal blocks, from data converters to bias and clocking circuits, on advanced CMOS process nodes.
You will work in tight feedback loops with circuit designers, translating schematic intent into silicon-accurate layout, and you will be the team's authority on matching techniques, parasitic-sensitive floorplanning, and the physical verification flows that get a design tapeout-ready.
