Senior Development Engineer – Photonic Devices / VCSEL Epitaxy (m/f/d)

The Senior Development Engineer will drive the design and optimization of epitaxial stacks for VCSEL and related photonic device structures. The role focuses on translating device‑level requirements into robust epitaxial designs, using advanced semiconductor physics and numerical simulations to guide development and optimize performance, yield, and reliability. This position is ideal for someone with a strong academic and/or R&D background in semiconductor physics and photonic devices who wants to work at the interface of epitaxy, device design, and product development. 

Key Responsibilities

• Design and simulate epitaxial layer stacks for VCSEL and other photonic device structures to meet optical, electrical, and thermal device requirements.
• Develop and refine device and epitaxy simulation models (e.g., optical cavity / mode simulations, carrier transport, thermal behavior) to suppo...
