Senior Mechanical Engineer

Job Description

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're looking for a hands-on Senior Mechanical Engineer to help design and develop the mechanical systems behind our optical switching platform.

You'll work closely with our Mechanical Engineering Manager and cross-functional teams across photonics, electrical engineering, packaging, manufacturing, and operations to develop precision mechanical assemblies that enable world-class optical performance.

This is an ideal opportunity for an engineer who enjoys solving difficult multidisciplinary engineering problems, wants significant ownership over product design, and is interested in growing into future technical leadership, while preferring to remain deeply involved in hands-on engineering today.Key Responsibilities
