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 a Sr. Engineer in the Test Hardware group, you will drive the development and maturity of the Test Equipment required to deliver Ayar Labs’ next generation SuperNova and TeraPHY products. Responsibilities include interfacing with Product Development Engineers, Design Engineers, and Validation Engineers to create test software and equipment that deliver trustworthy data to our partners and customers. You will be joining a small team in a dynamic startup environment, where each member is able and expected to take on a wide range of responsibilities, and to learn and grow with the company.
