Location: Remote (within India)

Employment Type: Full time

Years of Experience: 4+ years of experience

Role:

We are seeking an Optical Engineer specializing in Automotive Lighting Simulation using Ansys SPEOS (4+ years) with a keen interest in headlamp, signal lamp, and interior lighting design, photorealistic rendering simulations in SPEOS. A basic knowledge in Zemax OpticStudio is appreciated. He/She will be responsible for designing and analyzing automotive lighting systems (headlamps, DRLs, tail lamps, fog lamps, interior ambient lighting), performing photometric and colorimetric simulations in SPEOS, ensuring compliance with automotive lighting regulations (ECE, SAE, FMVSS) and creating such regulatory templates is also preferred, and generating optical/lighting system designs as per client and OEM requirements.

Key Responsibilities:

- Design, build, validate, and optimize automotive lighting optical systems

(reflectors, lenses, light guides, projector modules) using SPEOS.
- Perform photometric, colorimetric, and illuminance simulations for headlamps, tail lamps, DRLs, fog lamps, and interior lighting using SPEOS.
- Conduct regulatory compliance simulations and reporting as per ECE, SAE,

FMVSS, and other regional automotive lighting standards and create them if required.
- Perform stray light, ghost image, glare, scattering, and reflection analysis for lighting and sensor-integrated optical systems in Speos or else in Zemax is also appreciated.
- Model and validate LED/light source characteristics, sources libraries, and source-to-optic coupling in SPEOS.
- Use SPEOS material library and apply appropriate material/coating/surface finish models (textures, coatings, diffusers,



reflective/absorptive surfaces)

to meet styling and performance targets.
- Perform CAD integration and opto-mechanical modeling for lighting assemblies (SolidWorks/CATIA/NX to SPEOS workflow).

Utilize SPEOS GPU/HPC-based rendering for faster simulation turnaround and conduct CPU vs. GPU vs HPC trade-off studies.
- Propose design mitigation strategies (baffles, coatings, apertures, surface treatments) to resolve stray light, hotspot, or glare issues.
- Generate clear technical reports, simulation documentation, and presentations for internal reviews and OEM/client submissions.
- Stay updated with the latest automotive lighting trends, SPEOS tool capabilities, and simulation methodologies (adaptive lighting, matrix LED,

pixel lighting, etc.).
- Collaborate with senior optical/lighting engineers, styling, and mechanical teams to integrate optical performance with design intent and manufacturability.

Required Qualifications

- Bachelor's/Master's/Ph.D. degree in Optics, Physics, Mechanical,

Photonics, Automotive Engineering, or related field experience.
- Hands-on experience with automotive lighting design and simulation using

Ansys SPEOS only(requirement).
- Strong knowledge of photometry, colorimetry, and automotive lighting regulations (ECE/SAE/FMVSS).




- Solid analytical and problem-solving skills with the ability to interpret simulation and photometric results.
- Experience with optical material properties, coatings, textures, and surface finishes relevant to automotive lighting.
- Proficiency in CAD integration (CATIA/SolidWorks/NX) for opto-mechanical system modeling.
- Knowledge of light sources (LED, laser) and source modeling/characterization.
- Excellent communication and technical reporting skills.

Preferred Qualifications

- Experience with advanced lighting systems — matrix LED, adaptive driving beam (ADB), pixel/DMD-based headlamps, and projector module design.
- Basic to intermediate knowledge of Zemax OpticsStudio for optical system design is really appreciated.
- Familiarity with Python for simulation automation, post-processing, and data analysis is also appreciated

Knowledge of ODX export workflows and mechanical design integration for

Speos-Zemax Opticstudio.

- Hands-on experience correlating lab-based photometric/goniophotometer measurements with SPEOS simulation results.
- Exposure to stray light and glare analysis in combined lighting-sensor

(camera/LiDAR) systems.

What We Offer:

- Opportunity to work on cutting-edge automotive lighting systems for global OEMs and Tier-1 clients.
- Collaborative and multidisciplinary environment spanning optics,

mechanical, and styling teams.
- Travel to customer engagements and technical presentations.
- Professional development in advanced optical simulation and automotive lighting design tools.
- Research and Development opportunities with commercial software might be feasible, if interested.
