Photonics Circuit Designer (f/m/d)

As a Photonics Circuit Designer, you own the schematic, layout, and physical realization of photonic ICs, translating concepts into tape-out-ready blocks. You will collaborate with the Photonics Architect, device and simulation teams, EIC, and packaging engineers to align circuit design with manufacturing requirements. Your work bridges circuit design, IC implementation, and semiconductor fabrication, ensuring manufacturability and performance. This role offers an opportunity to shape high-bandwidth, energy-efficient photonic solutions at scale. You will contribute to a human-centered, innovation-driven culture that values cross-functional impact and continuous learning.
