The application window is expected to close on: 05/30/2026 Job posting may be removed earlier if the position is filled or if a sufficient number of applications are received . This is a hybrid role with three day per week at our Holmdel, NJ office. The Acacia division of Cisco is looking for an integrated photonics test engineer. Meet the Team Acacia (part of Cisco) is a market leader in high-speed coherent optical transceivers, pioneering the development of coherent pluggable transceivers. Acacia’s coherent products are deployed by all hyperscalers to connect their Data Centers over distances from a few kilometers to thousands of kilometers and even in submarine networks. The emergence of AI has drastically increased the demand for Acacia’s coherent transceivers. Acacia’s coherent transceivers are also being used in space applications and are expected to be used inside data centers as interconnect speeds continue to increase. Acacia is also entering the PAM4 Client market and is expected to be a key provider of PAM4 solutions, including a 1.6T PAM4 DSP. The Photonic Integrated Circuits (PIC) team is a dynamic group that develops advanced photonics chips for optical communications products. Acacia takes pride in providing and fostering a collaborate environment to ensure success and personal growth.
