About Us:

nEye.ai, a well-funded optical switch startup, is poised to revolutionize the future of data centers. nEye’s MEMS-based silicon photonics optical circuit switches (OCS) eliminate critical bottlenecks in AI processing by enabling direct optical connections among thousands of GPUs and memory units. The company's SuperSwitch is an ultra-low power consumption, high radix, compact chip-scale design, offering hyperscale data centers enhanced performance, efficiency, and scalability.

Job Overview:

We are seeking a highly skilled and strategic Director of Mechanical Engineering to be the primary owner and driver of all mechanical aspects of our product development. In this pivotal role, you will be the primary technical authority for mechanical design, simulation, and manufacturing, serving as the central interface between mechanical engineering and all other teams within the company. This is a unique opportunity for an accomplished individual contributor who is also ready to lead a small team of engineers, or a prior manager that enjoys leading a small, focused team. Your impact in this role will be measured by your team's accomplishments.

You will be responsible for building and organizing the team that creates robust and reliable mechanical designs meeting the stringent requirements of the telecom and data center markets. You will own all stress/strain, modal, and thermal simulations, ensuring our products are optimized for performance and durability. This role spans the entire product lifecycle, from initial concept and vendor development to first article inspection and engineering change control. You will work closely with packaging experts on the team that specialize in particular areas of the product design.
