Photonics Design Engineer

As a Photonics Design Engineer in our Silicon Photonics Core R&D team, you will drive the evolution of high-speed optical interconnects for AI clusters and data centers. In our fabless design house, you will bridge CMOS electronics with photonic integrated circuits (PIC), optimizing energy-per-bit performance for 800G and 1.6T applications. Your work directly enables scalable, power-efficient silicon photonics solutions.

Responsibilities:

• Design and simulate active/passive integrated photonic devices and circuits
• Develop photonic device models and optimize performance metrics (efficiency, bandwidth, loss)
• Collaborate with fabrication teams (foundries) to ensure design manufacturability (DFM)
• Conduct design verification and performance analysis via simulation and experimental data correlation
• Support product development from concept to volume production
• Document specifications and support test/integration teams
• Other ad hoc duties as assigned

Requirements:

• Master’s Degree with 3 years' industry experience or PhD in EE/Optics/Physics
• Proficiency in photonic simulation tools (Lumerical, COMSOL, etc.)
• Strong knowledge of photonic device principles (waveguides, modulators, detectors, lasers)
• Experience with semiconductor fabrication processes and DFM
• Familiarity with scripting for automation (Python, MATLAB)
• Background in silicon photonics, III-V, or hybrid integration is a plus
• Strong analytical skills and ability to work in cross-functional teams
