Integrated Photonic Test Engineer

The application window is expected to close on: 08/25/2026. 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 days per week at our Holmdel, NJ office.

The Acacia division of Cisco is a market leader in high-speed coherent optical transceivers, pioneering the development of coherent pluggable transceivers that are deployed by hyperscalers to connect data centers over distances from a few kilometers to thousands of kilometers, even in submarine networks. The market growth driven by AI has amplified demand for Acacia’s cohesive transceivers and their usage in space and data center interconnects.

Acacia is also entering the PAM4 Client market and is expected to be a key provider of PAM4 solutions.

As an Integrated Photonic Test Engineer, you will develop and support Cisco’s next‑generation integrated photonic components for telecommunications, data centers, and AI infrastructure. You will devise, build, and execute engineering tests for novel optical components in Cisco’s silicon photonics product portfolio.

• Develop, build, and perform engineering tests to support integrated photonic components and circuits on die, wafer, and assembly levels.
• Analyze and correlate optical test data with design and process parameters to optimize device performance for high‑speed photonics applications.
• Apply data analytics leveraging AI/ML for proactive problem detection and resolution.
• Communicate clear, concise, and actionable data‑driven analysis to cross‑functional teams, including Design, Assembly, Test, Qualification, and Foundry partners.

• Bachelor’s degree + 7 years of related experience, or Master’s degree + 4 years, or PhD + 1 year of related experience.
• Knowledge of solid‑state physics, integrated photonics, and opto‑electronics.
• Experience in hardware and software automation of photonics testing.

• Ph.D. with +3 years of experience.
• Prior experience with commercial large‑scale photonic circuit testing developments.
• Prior experience building optical testing setups and systems for integrated photonics and performing hands‑on testing.
• Strong programming skills for testing automation using Python, Matlab, C#, or LabVIEW.
• High proficiency in statistical programming languages for data analysis and modeling, and experience with commercial statistical applications such as JMP.
• Strong SQL skills for complex data extraction from relational databases.
• Experience testing RF and high‑speed optical components.
• Prior experience specifically with silicon photonics or other integrated high‑speed photonic platforms is a strong plus.
