• Take ownership of technical work packages and R&D projects, ensuring effective execution and measurable progress
• Develop, evaluate, and industrialize new hardware concepts, assembly processes, and manufacturing approaches for fiber handling and integration
• Plan and execute experiments, analyze results, and translate findings into practical product and process improvements
• Work hands-on in the laboratory, including prototyping, characterization, validation, and process optimization
• Collaborate with customers, research partners, suppliers, and interdisciplinary teams to transform innovation into manufacturable solutions
• Mentor junior engineers and technicians while fostering a results-oriented engineering culture
• Contribute to technology scouting, future product concepts, and technology roadmaps for optical fiber interconnects
• Act as a technical driver by aligning stakeholders, challenging existing approaches, and maintaining development momentum

Your Profile

• Master's degree in Photonics, Physics, Electrical Engineering, Telecommunications, Mechanical Engineering, or a related field
• At least 5 years of professional experience in photonics, fiber optics, optical packaging, telecom/datacom, or high-precision automation
• Experience coordinating technical activities, mentoring colleagues, or taking responsibility for project deliverables is an advantage
• Hands-on mindset and enthusiasm for experimental development work
• Enjoy working hands-on in the laboratory and using experimental approaches to solve challenging technical problems
• Strong analytical and problem-solving skills
• Demonstrated ability to take ownership, drive topics proactively, and turn ideas into tangible results
• High intrinsic motivation, curiosity for technology development, and the persistence to overcome technical challenges
• Ability to motivate colleagues, maintain momentum in development projects, and contribute to ambitious team goals

We also welcome applicants from related fields such as optical connector technologies, fiber processing, cable assembly, or precision manufacturing who are looking to transition into advanced photonics technologies.

We offer

• Security and Flexibility for Your Future: Permanent employment contract, flexible working hours, and an attractive compensation package including a company pension scheme
• Work on Technologies That Shape the Future: Contribute to cutting-edge photonics technologies for AI applications, data centers, and next-generation optical communication solutions
