Résumé du poste

THEMA Foundries in Belgium seeks a Photonic Design Engineer to design, simulate, and optimize integrated photonic circuits for advanced semiconductor applications. You translate system requirements into robust photonic designs and collaborate with multidisciplinary teams from concept to production.

Responsibilities include design and optimization of III-V devices, misalignment-tolerant couplers, and developing PDKs, focusing on manufacturability, yield and reliability in a fast-paced foundry

Qualifications

• Master’s degree or PhD in Photonics, Optical Engineering, Electrical Engineering, Physics, or related field.
• 3+ years experience in integrated photonics design.
• Experience with photonic and semiconductor device design and simulation tools (Lumerical, PhotonDesign, COMSOL or equivalent).
• Deep understanding of semiconductor device physics, III-V laser and amplifier operation is a strong asset.
• Experience with photonic circuit layout (IPKISS, GDSFactory).
• Familiarity with photonic integrated circuit platforms (silicon and/or silicon nitride); heterogeneous integration concepts are a strong asset.
• Strong analytical and problem-solving skills, data-driven and team-oriented mindset.
• Ability to collaborate across design-, process-, test-, and product teams in a fast-paced foundry environment.
• Fluent in English; knowledge of Dutch or French is an advantage.

Responsabilités

• Design and optimize III-V devices, including SOAs and on-chip semiconductor laser sources.
• Design misalignment-tolerant coupling structures and mode transformers for efficient light coupling.
• Perform optical, electrical, and thermal modelling to predict device performance.
• Develop and maintain design rules, PDKs, and compact models for active building blocks.
• Analyze characterization data to close the loop between design, fabrication, and measured performance.
• Support productization, documenting designs and contributing to yield and reliability improvements.

Description du poste

As a Photonic Design Engineer, you are responsible for designing, simulating, and optimizing integrated photonic circuits for advanced semiconductor applications. Your focus is on translating system requirements into robust photonic designs, collaborating with multidisciplinary teams, and supporting the development of innovative photonic technologies from concept through production. Through modelling, design verification, and continuous improvement, you contribute to high-performance, manufacturable, and reliable photonic solutions.

Your responsibilities

• Design and optimize III-V devices, including semiconductor optical amplifiers (SOAs) and on-chip 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

• Master’s degree or PhD in Photonics, Optical Engineering, Electrical Engineering, Physics, or a related field.

• 3+ 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 laser and amplifier operation is a strong asset.

• Experience with photonic circuit layout (e.g. IPKISS, GDSFactory).

• Familiarity with photonic integrated circuit platforms (silicon and/or silicon nitride); experience with heterogeneous integration concepts is a strong asset.

• 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.
