We are seeking a Senior Experimental Physicist to drive the development of CREDO’s next-generation laser-based silicon photonics platforms.

In this role, you will bridge the gap between design and physical realization, owning the integration, characterization and optimization of semiconductor lasers with silicon photonic integrated circuits (PICs).

You will design advanced experiments, build state-of-the-art electro-optical testing infrastructure, and leverage data-driven insights to push the boundaries of device performance and yield.

Responsibilities:

· Develop CREDO’s Laser testing platform capabilities and automation, Conduct Experiments and analyze test results to advance the development of new products.

· Own the critical interface and integration path between semiconductor lasers (e.g., III-V/DFB) and silicon photonic devices. Drive cross-functional efforts to optimize coupling efficiency, electro-optical performance and reliability.

· Utilize systematic Design of Experiments (DOE) to identify performance bottlenecks, improve device yield, and transition prototypes to robust, high-volume manufacturable products.

· Lead root-cause failure analysis investigations for active silicon photonic devices, collaborating with fabrication and packaging teams to implement corrective actions.

Required Qualifications and Experience:

· 5–10 years of hands-on R&D experience in a multidisciplinary, high-tech industrial environment (silicon photonics or semiconductor laser industry preferred).

· Hands-on experience with design and assembly of custom electro-optical test and measurement stations.

· Strong proficiency in statistical data analysis, DOE principles, and statistical software tools (e.g., JMP, MATLAB, or Pandas/SciPy).

Desired Skills (Nice to Have)

· Experience with sub-micron active alignment systems and optical packaging processes.

· Familiarity with photonics and optics simulation tools (e.g., Lumerical, RSoft, Z-max)

· proven programming skills (Python highly preferred) for test automation, instrument control and data acquisition.

Education:

· MS/PhD
