Optical Packaging Engineer (f/m/d)

Optical Packaging Engineer (f/m/d)

Shape the future of Photonic Semiconductor packaging

Location: Dortmund, Germany
Employment Type: Full-time (40 hours/week) | Permanent

At Innolume, we develop innovative optoelectronic semiconductor technologies for next-generation communication, sensing and photonic applications. Our expertise ranges from advanced quantum-dot and quantum-well technologies to customized photonic devices tailored to our customers' requirements.

To strengthen our engineering team, we are looking for an experienced Optical Packaging Engineer (f/m/d) who is passionate about turning advanced photonic technologies into robust, scalable and production-ready solutions.

In this role, you will take ownership of optical assembly and packaging processes—from concept and process development to industrialization and continuous improvement. You will work hands-on with advanced optical components and assembly technologies and collaborate closely with production, R&D and quality.

If you enjoy combining photonics, precision engineering and manufacturing and want to see your solutions move from development into real-world production, we would love to meet you.

• Develop and optimize optical assembly and packaging processes for photonic semiconductor devices
• Take technical ownership of assembly equipment, tooling and related measurement processes
• Work hands-on with lensed fibers, collimators, FAC and SAC lenses and other optical components
• Develop and implement advanced optical coupling and thermal management concepts
• Optimize bonding processes, including epoxy and eutectic bonding
• Apply structured experimentation and statistical process control (SPC) to improve process capability, quality and yield
• Transfer new processes and technologies from development into stable production
• Analyze technical failures, troubleshoot complex process and equipment issues and implement sustainable solutions
• Collaborate closely with Production, R&D, Quality and other engineering teams
• Prepare technical and process documentation, including development plans, engineering reports, SOPs and work instructions
• Train and support production teams on new equipment and processes
• Support engineering changes, deviation processes and continuous improvement initiatives
• Ensure compliance with applicable EHS requirements and company standards

Required

• Bachelor's or master's degree in photonics, optical engineering, applied physics, electrical engineering or microsystems engineering or a related technical field
• Professional experience in optical or electro-optical packaging, assembly or process engineering
• Hands-on experience with optical alignment, coupling and assembly technologies
• Experience with laser sources, photodetectors and optical components such as lensed fibers, collimators or micro-optics
• Experience with advanced assembly equipment and automated motion or positioning systems
• Strong analytical, troubleshooting and problem-solving skills
• Ability to independently manage technical projects while collaborating effectively with multidisciplinary teams
• Fluent English language skills, both written and spoken

Nice to have

• Experience with semiconductor back-end or photonic device manufacturing
• Experience with wire bonding, die bonding, epoxy bonding or eutectic bonding
• Knowledge of SPC, Design of Experiments (DoE) and statistical data analysis
• Programming experience with Python and/or LabVIEW
• Experience with 3D CAD and technical drawings, preferably SolidWorks
• Experience transferring engineering processes into volume production
• German language skills are an advantage

• A permanent position in an innovative and international high-tech environment
• The opportunity to work at the forefront of photonics and semiconductor technology
• Hands-on responsibility for technologies and processes from development through industrialization
• Challenging projects with a high degree of technical ownership and room to contribute your own ideas
• Close collaboration with experienced colleagues across R&D, engineering and production
• Individual internal and external training and professional development opportunities
• Flexible working hours in a collaborative working environment
• 30 days of annual leave
• Attractive additional benefits, including company parking, company events, free beverages and fruit
• Gift vouchers for special occasions such as birthdays
• Additional benefits after successful completion of the probationary period, including commuting allowance, mobility support, meal subsidies and other attractive perks
