GaN Technology Engineer

GaN Technology Engineer - Onsite working in Spain 

The Engineer at a foundry specializing in the fabrication and design of photonic components based on Gallium Nitride (GaN) plays a key role in supporting the development, optimization, and characterization of integrated photonic devices. Engineers are responsible for executing tasks under supervision, developing technical skills, and contributing to project deliverables.

Responsibilities: 

• Execute assigned tasks in the design, simulation, and layout of integrated photonic devices using GaN.
• Assist in the design, simulation, and layout of GaN-based photonic and optoelectronic devices (e.g., LEDs, laser diodes).
• Support process development and optimization for GaN-based device fabrication.
• Participate in technical reviews and internal training.
• Conduct data analysis and contribute to technical documentation and reporting.
• Collaborate with process engineers and designers to troubleshoot device performance and yield issues.
• Follow cleanroom protocols and ensure compliance with safety and quality standards.
• Document results and maintain accurate records of experiments, measurements, and fabrication steps.

Required Education:

• Bachelor’s or Master’s degree in Engineering, Applied Physics, Photonics, Materials Science, Optoelectronics, or a related field.
• Academic or research experience in III-V semiconductors or photonic integration is highly valued.

Technical Skills:

• Solid understanding of semiconductor physics, photonics, and optoelectronic device principles.
• Familiarity with GaN-specific fabrication processes.
• Experience with photonic design and simulation tools such as:
  • KLayout, Cadence, or IPKISS
  • Lumerical (FDTD, MODE)
  • COMSOL Multiphysics
• Knowledge of PDKs (Process Design Kits) and DRC (Design Rule Checking).
• Hands-on experience with optical/electrical test setups and equipment (e.g., optical spectrum analyzers, probe stations, power meters).
• Experience with device simulation tools (e.g., Lumerical, Silvaco, COMSOL) for optical, electrical, and thermal modeling.
• Programming/scripting skills in Python, MATLAB, or similar for data analysis and automation.
• Familiarity with cleanroom fabrication processes: photolithography, etching, deposition, metallization, wafer bonding, etc.
• Proficiency in technical English, both written and spoken.
