Graphene Photonic Component Designer (f/m/d)

Permanent employee, Full-time · Aachen

About us

We see the semiconductor industry as a realm of possibility. We see opportunity. We see the profound impact that our graphene solutions will have in transforming the industry. We invite you to join us in driving change with our fundamentally human-centered approach, uniting bright minds around a shared vision. The vision is: Prove to everybody that you can make a fundamental change. Prove with your knowledge and skills how things can be done differently. Together, we can change the paradigm of how the world connects

About our technology

The semiconductor industry’s growing demand for more powerful chips with higher bandwidth and lower power finds its solution in our technology. We connect chips to high-throughput, low-delay computing networks. The key lies in harnessing the physical properties of graphene to combine electronic computing with photonic communication, allowing countless chips to interact almost as if they were one. Our graphene photonic innovation increases computing power and efficiency to a new order of magnitude    

In short, we connect chips to create powerful and energy-efficient networks, overcoming connectivity limitations in the semiconductor industry. We deliver the graphene solution

The Role

Black Semiconductor is seeking a Graphene Photonic Component Designer (f/m/d) to play a key role in building our graphene-based, high-speed optical transceiver platform. You will contribute to the design and simulation of both passive and active photonic components. Your work will span from designing fiber-to-chip and chip-to-chip coupling structures in silicon nitride, to the development of advanced graphene electro-optic modulators, photodetectors, and polarization control components

To join our team, you should be excited to

Develop graphene-based photonic components, including modulators, photodetectors, resonant structures, and active gratings, for a high-speed optical transceiver platform
Design passive photonic components in silicon nitride (e.g., for polarization control, fiber-to-chip and chip-to-chip coupling)
Drive innovation in 2D material device structures, focusing on efficiency, integrability, and novel photonic functionalities
Create and maintain PDK building blocks, ensuring layout quality and up-to-date libraries for photonic design workflows
Design test structures to validate models and verify performance across fabrication and environmental variations
Optimize component designs using fault-tolerant principles and best practices in Design for Manufacturability (DFM) and Design for Functionality (DFF), including mask layout and synthesis
Collaborate cross-functionally with the process integration team on feasibility studies (e.g., for loss and bandwidth improvements), with the packaging designer on coupling interfaces, and with the characterization team on statistical data analysis

Your Qualifications

M.Sc. or Ph.D. in Electrical Engineering, Optical Engineering, Physics, or a related field
3+ years of experience in integrated photonics
Proficiency in photonic simulation tools: Lumerical MODE/FDTD, COMSOL or equivalent
Familiarity with graphene device simulation tools and 2D materials modeling software
Knowledge of electro-optic simulation platforms
Programming skills in Python and working knowledge of Git for version control
Experience with photonic layout tools such as gdsfactory, Nazca, or OptoDesigner
Hands-on experience with optical characterization equipment is a plus
