Photonic Design Engineer

Senior

Your Responsibilities

• Design and optimize III-V devices, including semiconductor optical amplifiers (SOAs) and semiconductor laser sources.
• Design misalignment-tolerant coupling structures and mode transformers that enable efficient light coupling between active devices and photonic waveguides.
• Perform optical, electrical, and thermal modelling and simulation to predict and validate device performance.
• Develop and maintain design rules, process design kits (PDK), and compact models for active building blocks.
• Analyze characterization data to close the loop between design, fabrication, and measured performance, and drive continuous improvement.
• Support productization, documenting designs and contributing to yield and reliability improvements.
  

Qualifications And Experience

• Masters degree or PhD in Photonics, Optical Engineering, Electrical Engineering, Physics, or a related field.
• 5+ years experience in integrated photonics design.
• Experience with photonic and semiconductor device design and simulation tools (e.g. Lumerical, PhotonDesign, COMSOL, or equivalent.
• Deep understanding of semiconductor device physics, in particular III-V semiconductor lasers.
• Experience with photonic circuit layout (e.g. IPKISS, GDSFactory).
• Familiarity with photonic integrated circuit platforms.
• Strong analytical and problem-solving skills, combined with a structured, data-driven, and team-oriented mindset.
• Ability to collaborate effectively across design-, process-, test- and product teams in a fast-paced foundry environment.
• Fluent in English; knowledge of Dutch or French is considered an advantage.
