Job description

Our client is a technology-oriented company developing advanced optical fiber and laser beam guidance solutions for demanding photonics applications. The organization combines optical engineering, laser processing, precision manufacturing, and measurement technologies to develop and industrialize sophisticated fiber-based components and systems for international customers.

Its activities rely on close collaboration between development, manufacturing, quality management, product management, and customers, with a strong focus on technical rigor, experimental validation, manufacturing feasibility, and traceability. The company operates in an international and technically demanding environment, offering engineers the opportunity to contribute across the complete development cycle from initial design concepts and experimental work through manufacturing process development and product validation.

Mission

The Optical Fiber Development Engineer will be responsible for developing and improving optical fibers and laser beam guidance systems, combining experimental photonics expertise with manufacturing-oriented engineering. The role will design concepts and production processes, plan and evaluate experiments, characterize optical and mechanical properties, and collaborate across technical and commercial functions to translate development work into reliable and manufacturable solutions.

Responsibilities

Optical Fiber and Beam Guidance Development

• Develop and continuously improve optical fibers and laser beam guidance systems.
• Perform laser processing of optical fibers as part of development and manufacturing process activities.
• Create technical design concepts and translate development requirements into practical engineering solutions.

Manufacturing Process Development

• Develop manufacturing processes for optical fiber and beam guidance products.
• Work closely with manufacturing teams to ensure that development concepts can be implemented reliably in production.
• Support the transition of technical developments into controlled and repeatable manufacturing processes.

Experimental Development and Characterization

• Plan, execute, and evaluate experiments related to optical fiber technologies and associated systems.
• Select appropriate measurement methods according to experimental and development requirements.
• Test and measure relevant optical and mechanical properties and analyze the resulting data.

Cross-functional Collaboration and Documentation

• Collaborate with manufacturing, quality management, and product management throughout development activities.
• Work with customers in domestic and international environments on relevant technical topics.
• Maintain clear technical documentation and ensure appropriate traceability of development, experimental, and measurement activities.

Required Qualifications

• University degree in physics, photonics, or a comparable technical or scientific discipline.
• Professional experience in optical fiber development, photonics, laser processing, or a closely related field.
• Experience working with CAD systems, particularly SolidWorks.
• Demonstrated scientific and analytical thinking supported by relevant professional or technical achievements.
• Ability to independently plan and execute technical development and experimental activities.
• Fluent German and English language skills.
• Strong communication and teamwork capabilities.
• High level of reliability, attention to detail, and ability to quickly understand complex technical subjects.

Preferred Experience

• Experience developing or improving optical fibers and laser beam guidance systems.
• Practical experience with laser processing of optical fibers.
• Experience developing manufacturing processes for photonic or precision-engineered products.
• Experience selecting measurement methods and characterizing optical and mechanical properties.
• Previous collaboration with manufacturing, quality management, product management, and international customers.
• Independent, meticulous, results-oriented, and collaborative working style.
