Inpho is a fast-growing startup, focused on developing cutting‑edge optoelectronic solutions for next‑generation communications, and photonic systems. Our multidisciplinary team is pushing the boundaries of innovation in integrated photonics and semiconductor packaging.

Inpho’s new class of electro‑photonic chips is poised to revolutionize and disrupt the optical interconnect market. Utilizing this new class of chips enables existing optical interconnect systems to be built at much lower cost, new architectures to be deployed that provide significantly higher price / performance, and a whole new generation of higher speed interconnect to be built that to date have been impossible.

About the Role

We’re looking for a Principal Test Engineer to join our NPI Engineering team. Reporting to the VP Engineering, New Product Development, this critical role will lead the development, implementation, and optimization of production high volume test solutions for a new class of high performance electro‑optical designs. This role requires strong technical expertise in ATE development, test architecture, DFT integration, high performance hardware design, and a passion for building robust, scalable, and cost‑effective test solutions.

This is a unique opportunity to trailblaze next‑generation test solutions for a new class of high performance electro‑optical designs. The successful candidate will be responsible for developing test and characterization platforms, to ensure Inpho’s cutting‑edge products are delivered with high quality.
