About The Position

Lumai is redefining how the world computes with its AI accelerator for data centers that uses 3D optical compute. This technology offers significantly faster speeds, greater scales, and lower energy consumption compared to traditional methods, aiming to transform AI and compute infrastructure economics. Lumai, a University of Oxford spinout founded in 2022, specializes in using optical processing to accelerate large language models and transformer-based AI systems. The company has secured over $15 million in investment and is rapidly scaling to deploy the fastest optical compute globally. The role of Senior Solutions Architect is crucial for bringing Lumai's optical compute inference platform to market, acting as the technical lead for customer engagements.

Requirements

• Substantial experience in a solutions architecture, technical pre-sales, or senior field engineering role within AI infrastructure, high-performance compute, semiconductors, or a comparable deep-tech hardware domain.
• Strong working knowledge of AI inference at scale, including how large language models are deployed.
• Familiarity with data center architecture: rack power, thermal, networking, and integration with existing software stacks.
• Demonstrated ability to lead technical discovery with sophisticated customers and translate requirements into a solution.
• Comfortable operating in a fast-moving, sometimes ambiguous, pre-product environment.

Nice To Haves
