Photonic Component and Circuit Designer (f/m/d)

Photonic Component and Circuit Designer (f/m/d)

Overview
As a Photonic Component and Circuit Designer, you will play a key role in the design and simulation of high-speed WDM/DWDM optical transceiver systems and bridge component-level photonic design with system-level architecture. You will be responsible for developing integrated solutions optimizing system performance.

The Role

As a Photonic Component and Circuit Designer (f/m/d) , you will design and simulate high-speed optical components and circuits, focusing on WDM/DWDM transceiver systems and bridging component-level photonic design with system-level architecture. You will be responsible for developing integrated solutions that optimize system performance.

• Design and benchmark passive low-loss components for WDM systems
• Develop active graphene-based components
• Run photonic circuit-level simulations to optimize device performance
• Apply fabrication-tolerant design optimization strategies
• Design test structures and implement design-for-test (DFT) methods
• Perform component and circuit layouting
• Deliver PDK-ready components to support scalable integration

Your Qualifications

• M.Sc. or Ph.D. in Electrical Engineering, Optical Engineering, Physics, or a related field
• 3+ years of experience in integrated photonics device physics and modeling
• Experience in design, simulation, analysis, and optimization of low-loss passive (and ideally active) components
• Proven record of developing devices that perform within specifications
• Experience in test structure development
• Background in integrated photonics platforms (ideally SiN)
• Proficiency with Lumerical products (Mode, FDTD, Interconnect)
• Programming skills in Python and familiarity with Git
• Familiarity with multiplexing devices (CMZI, AWG, ring resonators, MUX) is good to have
• Knowledge of optical link/circuit simulation is good to have
• Exposure to DFM, electronic-photonic co-design, and compact model generation is good to have
• Experience with PDK building block development is good to have
• Proficiency with layout tools (gdsfactory, Nazca, OptoDesigner) is nice to have
• Hands-on lab experience in photonic device characterization is nice to have
