Integrated Photonics Engineers focus on designing and developing integrated photonic devices and circuits, often working in fabrication and R&D. Optical Systems Engineers work on designing and optimizing complete optical systems, including components and integration. While both roles require optical engineering knowledge, the main difference lies in the scope: device-level vs system-level focus.
