About The Position

Ayar Labs is shattering AI data bottlenecks by moving data at the speed of light. As pioneers of co-packaged optics (CPO), we are using light instead of electricity to move data faster, further, and with a fraction of the energy needed to fuel the explosive growth of AI models. Backed by industry giants like NVIDIA, AMD, Mediatek and Intel and manufactured in partnership with the world’s leading semiconductor ecosystem, Ayar Labs’ co-packaged optics solution is key to unleashing next-generation AI scale-up architectures. As an Engineer in the Software Infrastructure group of the Product and Test Engineering department, you will be expected to execute assigned software development tasks independently, applying standard engineering techniques and judgment to adapt solutions that will enable high volume production of our SuperNova and TeraPHY parts. You will work closely with your colleagues in the Product and Test Engineering department to help them consolidate, standardize, test, and release instrument drivers, test recipes, and other software solutions. You will be joining a small team in a dynamic startup environment, where you are expected to take on a wide range of responsibilities with guidance from senior engineers and team leads, and to learn and grow with the company.
