• Collaborate with mechanical engineering teams to integrate optics into manufacturable luminaire designs.
• Work with suppliers to develop and evaluate optical components such as lenses, reflectors, and diffusers.
• Build and test prototypes, conduct photometric measurements, and validate optical performance using goniophotometers and integrating spheres.
• Analyze test data and iterate designs to improve performance, uniformity, and efficiency.
• Ensure compliance with relevant lighting standards and regulations (IES, UL, energy codes).
• Support new product development from concept through production release.

Key Competencies:

• Optical design and ray tracing
• LED optics and light distribution design
• Photometric testing and analysis
• Cross-functional engineering collaboration
• Product development lifecycle management

Education: Bachelor’s or master’s degree in Optical Engineering, Physics, Electrical Engineering, or related field.

Experience:

• 3+ years of experience in optical design for LED lighting or illumination systems (commercial, architectural, automotive, or consumer lighting).
• Strong understanding of non-imaging optics and illumination design.
• Experience with optical simulation and ray-tracing software.
• Knowledge of LED sources, color mixing, light extraction, and glare control techniques.
• Experience working with injection-molded optics, reflectors, and light guide technologies.
• Familiarity with photometric measurement equipment and lighting standards.

Preferred Skills:

• Experience designing optics for architectural or commercial luminaires.
• Familiarity with IESNA lighting standards and photometric files (IES/LDT).
• Experience with tolerance analysis and optical manufacturing constraints.
• Knowledge of human-centric lighting, color quality (CRI/TM-30), and glare metrics (UGR).
• Experience with CAD tools such as SolidWorks or PTC Creo.

Salary Range: $120,000 - $130,000 starting base plus bonus
