About the Job
We are looking for a highly skilled Photonics Design Engineer (f/m/d) to join the Semiconductor R&D team at our company in our Ecosystem. In this role, you will be responsible for designing and developing passive photonic components that power our graphene-based, high-speed optical transceiver platform.
As part of the team, you’ll help shape the chip-to-chip photonic connectivity roadmap. Working across fabrication, characterization, and process teams, you’ll deliver scalable, low-loss photonic solutions for next-generation semiconductor performance.
Join our Ecosystem company: A German hardware startup focused on designing and manufacturing groundbreaking microchips. The company develops energy-efficient, high-performance components with the potential to redefine global semiconductor connectivity through graphene photonics.
In this role, you’ll:
- Design passive photonic components in silicon nitride, including multiplexers and fiber-to-chip couplers
- Create, maintain, and update PDK building blocks in line with evolving requirements
- Develop test structures and support model validation through statistical data
- Explore and apply inverse design techniques and benchmark them against conventional methods
- Collaborate closely with the characterization team to improve yield, reduce optical loss, and support design iteration
- Work with process integration teams to ensure manufacturability, scalability, and performance
Your Profile:
- PhD or at least 3 years of professional experience in integrated photonics design
- Experience using Lumerical tools (e.g., MODE, FDTD, Multiphysics)
- Proficiency in Python and familiarity with Git workflows
- Strong layout design experience using gdsfactory, Nazca, or OptoDesigner
- Experience with inverse design techniques is a plus
- Hands-on experience with optical lab characterization is a plus
- Knowledge of Zemax is a plus
- Strong analytical and problem-solving skills with a structured, data-driven approach
- Excellent communication skills in English (written and spoken). German is a plus
Please note that this position is based in NRW region.
