As a senior technical contributor, you will combine hands-on engineering with technical leadership, working closely with System Engineering, Product Integration, Verification & Validation, Lifecycle Engineering and manufacturing partners to turn complex sensing concepts into reliable and scalable products.

What you’ll do:

• Lead the development and engineering realization of optical sensor subsystems throughout the product lifecycle.

• Translate product and subsystem requirements into robust optical sensing solutions.

• Develop fiber-optic sensing principles, sensor architectures, optical assemblies, packaging concepts, calibration methods and subsystem interfaces.

• Develop sensing solutions for temperature, pressure, heading and future sensing capabilities.

• Design and evaluate concepts, prototypes and engineering models through testing, characterization and analysis.

• Develop calibration methods and characterize sensor accuracy, repeatability, drift and environmental performance.

• Analyze test and verification results, identify failure modes and performance limitations, and drive technical improvements.

• Lead technical investigations, root cause analyses and engineering trade-offs related to sensor performance, stability and reliability.

• Work closely with multidisciplinary engineering teams to resolve integration and interface challenges.

• Support Verification & Validation and industrialization, improving manufacturability, calibration efficiency and production repeatability.

• Make and drive subsystem-level technical decisions while balancing performance, reliability, manufacturability, cost and risk.

• Identify technical risks and dependencies early and help teams find practical solutions.

• Contribute to design reviews and multidisciplinary technical discussions, creating alignment around technical direction.

• Mentor and support engineers within the optical sensing domain while remaining an active hands-on engineering contributor.

• Contribute to the continuous improvement and long-term development of optical sensing technologies and engineering practices at Optics11.

Why Join Us?

• Join one of Europe’s most promising deep-tech scale-ups.

• Shape the future of a rapidly growing multidisciplinary R&D organization.

• Competitive salary and benefits package.

• Enjoy regular team activities and company events.

• Fresh team lunches provided 3 times/week.

Requirements

What you bring:

• A Master’s degree or PhD in Optical Engineering, Applied Physics, Photonics, Electrical Engineering, Mechanical Engineering or a related technical field.

• Strong experience in fiber-optic sensing, optical sensor development, photonics or precision optical systems.

• Solid understanding of optical physics, sensor design, optical assemblies and calibration principles.
