We at EDAG simply claim to be our customers' global mobility technology experts! EDAG Engineering Scandinavia AB is the Scandinavian subsidiary of the EDAG Group. We are now certified as "A GREAT PLACE TO WORK" with a top score! More and more customers are discovering our ability to deliver local engineering capabilities in a wide range of areas – often in combination with other global EDAG facilities, colleagues, and competencies to handle larger projects and commitments. We are seeking an experienced engineer with a passion for optical development and automotive lighting systems. In this role, you will be responsible for developing, simulating, evaluating, and optimizing advanced exterior and interior lighting solutions using ANSYS SPEOS. You will work closely with cross-functional teams and customers to transform simulation results into robust and innovative optical designs. Role Purpose We are looking for an experienced Optical Simulation Engineer to support the development of advanced automotive exterior and interior lighting systems in Gothenburg. The role requires strong hands-on expertise in ANSYS SPEOS, covering the entire simulation process from CAD preparation and optical model setup to simulation, analysis, optimization, and customer-ready reporting. Key Requirement The successful candidate must be able to independently build, execute, analyze, and optimize complete ANSYS SPEOS simulation models and translate simulation results into practical optical design improvements. Your Responsibilities

• Perform optical simulations using ANSYS SPEOS for automotive exterior and interior lighting systems.
• Develop and evaluate optical concepts for headlamps, rear lamps, interior lighting and ambient lighting.
• Set up complete SPEOS simulation models, including light sources and LED models, optical materials, surface properties, reflectors, lenses, light guides, diffusers, sensors and measurement planes.
• Perform ray-tracing simulations and evaluate luminous intensity, illuminance, luminance, homogeneity, optical efficiency and light distribution.
• Optimize optical concepts against customer requirements, styling targets and applicable legal requirements.
• Support early concept development as well as detailed optical development and design optimization.
• Prepare, clean and simplify CAD geometry for optical simulation and ensure suitable model quality.
• Analyze simulation results, identify root causes of optical performance issues and recommend design improvements.
• Correlate simulation results with physical measurements, prototypes and photometric test results where applicable.
• Work closely with optical design, mechanical design, electronics, thermal simulation and validation teams.
• Prepare clear simulation reports and present results and recommendations to project teams and customers.

Required Qualifications & Experience

• Degree in Physics, Photonics, Optical Engineering, Automotive Engineering or a comparable technical discipline.
• Professional experience in optical simulation and optical system development.
• Strong practical experience with ANSYS SPEOS is essential.
• Experience in automotive lighting systems is highly preferred.
• Ability to interpret photometric results and convert findings into concrete geometry and material improvements.
• CAD experience, preferably CATIA V5 or 3DEXPERIENCE, including preparation of geometry for simulation.
• Knowledge of LucidShape, LightTools or Zemax is an advantage.
• Understanding of automotive lighting regulations, such as UNECE and/or FMVSS, is beneficial.
• Structured, independent and analytical working style with strong problem-solving skills.
• Very good communication skills and the ability to explain technical results clearly.
• Fluent English is required. Swedish or German is an advantage.
