About the Role

We are looking for a new colleague to join our Sensors & Devices team at our Herning office. As our new Optical Design Engineer, you and the team will be responsible for developing advanced optical sensing solutions for wind turbine blades, contributing directly to improvements in structural health monitoring, load measurement, and reliability of the turbines.

Our sensing solutions consist of proprietary fiber‑optic FBG sensors and optical interrogators combined with advanced data analysis. Development and optimization are done in close collaboration with major wind turbine OEMs globally, and internally in an informal cross functional collaboration between R&D, Operation, Quality and Business.

You will work across the full product lifecycle—from concept and modeling to prototype validation and industrialization—and provide expert support to production and quality teams. In your work there will be opportunities to influence product design, test facilities, production processes and way of working.

Key Responsibilities

Optical Design & Development

• Translate functional requirements into robust sensor and interrogator designs
• Design, model, and optimize optical sensing concepts for use in wind turbine blades
• Build and validate simulation models using relevant optical design tools
• Support development of prototypes, test setups, and calibration methods

Industrialization & Production Support

• Collaborate with manufacturing engineers to ensure optical designs are scalable, repeatable, and cost‑effective for production.
• Troubleshoot optical assemblies, alignment issues, and component tolerances in production processes.
• Define inspection criteria, test methods, and quality checkpoints for optical components and assemblies.

Quality, Testing & Validation

• Conduct root‑cause analysis on field issues, production deviations, and non-conformities related to optical performance.
• Support continuous improvement activities and product upgrades.
• Document design decisions, test results, and quality findings in accordance with internal processes.

Qualifications

Professional Competencies

• MSc or BSc Degree in Engineering or Physics within photonics, electronics, or related field
• Strong analytical and problem‑solving skills
• Experience in free-space and fiber-optical system design and simulation
• Experience with fiber‑optic sensing, strain measurement, or structural monitoring.
• Familiarity with production processes (assembly, calibration, inspection).
• Experience working in renewable energy, wind turbine components, or similar industries.

Personal Competencies

• Structured, detail-oriented, and capable of driving tasks independently.
• Strong collaboration skills, especially with cross-functional teams (R&D, Production, Quality, Procurement).
• Ability to communicate technical topics clearly to both specialists and non‑specialists.
• Customer centric mindset with focus on quality and business opportunities

What We Offer

• A key role in shaping next‑generation optical sensing solutions for wind turbine blades.
• Close collaboration with experts in optical design, electronics, materials and data analysis
• A workplace focused on innovation, teamwork, collaboration and Customer First mindset
• Opportunities for personal and professional development.
