Photonics Process Development Engineer 2 Packaging and Tooling

Join our fast-paced and passionate team as a Photonics Process Development Engineer 2 focused on advanced packaging and tooling. As we scale, you will be instrumental in building our manufacturing foundation from the ground up. This is a dynamic, hands‑on role for a highly self‑directed engineer who thrives in an ambiguous, fast-moving environment.

You will play a critical role in establishing scalable photonic manufacturing processes that directly enable product performance, reliability, and cost targets. Your work will define how our technology transitions from prototype to production.

You will collaborate closely with device, optical, electrical, mechanical, and manufacturing engineers to transform delicate photonic designs into robust, manufacturable, high‑yield products.
