Lead Optical Sensing Development Engineer

We are looking for a Lead Optical Sensing Development Engineer to take technical ownership of the development and realization of our optical sensing solutions. In this role, you will develop robust fiber-optic sensing solutions used to measure parameters such as temperature, pressure and heading in demanding underwater environments. You will work across the full product development lifecycle, from early concepts and prototypes through testing, calibration, integration and industrialization. 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.
