Expert – Photonics & Optical Integration

In your role you will be responsible for the development and evaluation of electro-optical integration concepts within a multi-partner R&D project. You will focus on co-design across optical, electrical, and packaging domains, ensuring that concepts are feasible under system-level and manufacturing constraints. The position bridges photonic design, system requirements, and integration approaches, and contributes to the assessment of viable solutions for future development and industrialization.

• Develop and evaluate electro-optical integration concepts to support system-level objectives within the project
• Contribute to co-design activities across optical, electrical, and packaging domains to ensure technically consistent and feasible solutions
• Support definition and evaluation of coupling approaches, optical interfaces, and system architecture.
• Analyze simulation and experimental results to assess performance, limitations, and feasibility of integration approaches
• Identify technical challenges, constraints, and trade-offs between performance, manufacturability, and integration complexity
• Interface with external partners and research organizations to align technical approaches and consolidate results
• Support preparation of technical reports, presentations, and internal documentation
• Contribute to knowledge transfer within the organization regarding electro-optical integration approaches

• Master's degree or PhD in Photonics, Electrical Engineering, Physics, Electronics, or a comparable technical field
• Relevant experience in photonics, optical integration, or advanced packaging in an industrial research-driven environment
• Experience with Photonic integrated circuit (PIC) design, optical simulation, optical system design, optical communication systems or optoelectronic components is an advantage
• Experience with advanced packaging with optical integration (e.g. co-packaged optics, photonic assembly)
• Experience with substrate, PCB, or advanced packaging manufacturing environments, including an understanding of process capabilities and limitations, is considered an advantage
• Understanding of interactions between optical, electrical, and packaging domains
• Ability to analyze and interpret complex technical data (simulation and experimental)
• Ability to work across interfaces between research, development, and engineering teams
• Fluency in English

• A meaningful role with opportunities for long-term growth in an international environment
• Chance to actively contribute to AT&S´ success and to create value
• A structured and tailor-made onboarding program along with continual training opportunities
• Modern company canteen with freshly prepared meals every day
• Free parking spaces and e-charging stations
• Diverse health measures and a wide range of employee benefits
