Your career in a new light

A key role in advancing our optical expertise, with a direct impact on the realization of innovative lighting solutions at the highest level.

Your job:

• Analysis of initial optical requirements specifications from Product Management (target LDC, luminous flux, efficiency, UGR/glare, applicable standards, as well as mechanical and thermal constraints)

• Evaluation of standard optics versus customized solutions, including the preparation of well-founded decision proposals considering technical, economic, timeline, and sustainability aspects

• Creation and continuous maintenance of optical requirement specifications for external development partners (including light sources, CAD data, reference optics/LDCs, target values, as well as test and release criteria)

• Technical coordination and management of external optical developments for reflectors, lenses, TIR optics, optical systems, films, prisms, and diffractive optics

• Coordination of iterative design processes across optics, mechanics, electronics, and lighting design, ensuring seamless opto-mechanical integration

• Verification of developed concepts in close alignment with XAL Lighting Design through lighting planning, simulations, evaluation of measurement data, and comparison with specifications

• Planning, implementation, and evaluation of prototypes, soft tools, as well as 3D-printed and pre-series samples, including the preparation of release recommendations for tooling and external manufacturing

• Specification of materials, surfaces, tolerances, functional areas, temperature requirements, and handling guidelines for optical components

• Support of PDRS, quality planning, supplier approval, sampling, validation, and optical series release processes

• Analysis of deviations in light distribution, efficiency, color shift, uniformity, and visual quality, including the definition and implementation of necessary tool or design adjustments

• Continuous market analysis regarding standard solutions and technological innovations in the field of optics

• Acting as the main technical contact for external optics suppliers

Qualifications and skills:

• Completed technical education or degree in optics, photonics, physics, lighting technology, mechanical engineering, mechatronics, or a comparable field

• Several years of experience in optical development, ideally in architectural lighting, automotive lighting, or optical plastic/metal components

• Strong understanding of lighting engineering parameters such as LDC, luminous flux, efficiency, cut-off, UGR, glare parameters, uniformity, and color shift, as well as solid knowledge of photometric measurement techniques

• Knowledge of relevant manufacturing processes and materials, including PC, PMMA, silicone, aluminum, coatings, films, injection molding, extrusion, and PVD

• Experience working with external development partners and suppliers, as well as with technical documentation, specifications, validation, and series approvals

• Knowledge of Relux and DIALux; experience with additional simulation tools is an advantage

• Structured and self-reliant way of working, strong communication skills, a solution-oriented mindset, and enthusiasm for multidisciplinary and international collaboration

The position is classified with a minimum salary of € 4,000 gross per month. All employees stand out through their expertise, commitment, and personality. Depending on qualifications and experience, there is a willingness to offer a competitive and individually tailored package. Home office options are available after the onboarding phase in accordance with company guidelines.
