Who we are:

Inpho is delivering an industry first and the Holy Grail of high-speed optical communications—integrated high-speed electronics and optical components (lasers, laser modulators, photodiodes, etc.) on a single semiconductor substrate resulting in much, much higher speeds at lower power and lower cost.

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.

What we are looking for:

We want a highly motivated, experienced engineers with a proven track record of designing high speed optics for the PON and Data Center markets. There is a never-ending quest for higher speeds, lower power, and higher reliability. Inpho is delivering the products that can upend these markets and we are seeking engineers to join our team to make that happen.
