Process Engineer

GaN Technology Engineer Full-time 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.
