Optical Engineer (Adhesives & Films for Displays)
Job Summary:
We are seeking an Optical Engineer with expertise in adhesives and optical films used in display technologies. The ideal candidate will focus on evaluating, optimizing, and implementing optical adhesives, coatings, and films to enhance display performance, including light transmission, contrast, and durability. This role involves working closely with R&D, process engineering, and manufacturing teams to develop innovative optical bonding solutions for high-performance displays.

Key Responsibilities:
1. Technical lead for programs involving optical functional materials
2. Research and evaluate optically clear adhesives (OCA), liquid optical adhesives (LOCA), and optical films for display applications.
3. Analyze optical, mechanical, and adhesive properties to ensure optimal light transmission, low reflectivity, and strong adhesion.
4. Collaborate with material suppliers to qualify new adhesives, films, and coatings.
5. Conduct spectral, refractive index, and light scattering measurements to assess adhesive and film performance.
6. Perform haze, contrast, transmittance, and reflection evaluations to ensure optimal optical clarity.
7. Investigate and mitigate optical defects such as bubbles, birefringence, and Newton’s rings in bonded display assemblies.
8. Optimize lamination, bonding, and curing processes for optical adhesives and films.
9. Develop methods to reduce air gaps, enhance optical coupling, and improve adhesion durability.
10. Support pilot production and mass manufacturing to ensure proper application of optical materials.
11. Identify and troubleshoot adhesion failures, delamination, and environmental degradation in display assemblies.
12. Develop solutions to improve adhesion strength, moisture resistance, and optical stability over time.
13. Implement quality control measures for bonding uniformity and material reliability.

Qualifications:
1. Bachelor’s degree in Optical Engineering, Material Science, or related field.
2. 3+ years of experience in optical adhesives, coatings, and films for display technologies
3. Strong knowledge of optical properties of adhesives and films, including refractive index, transmittance, and haze.
4. Hands-on experience with spectrophotometers, ellipsometers, optical microscopes, and adhesion testing.
5. Familiarity with display assembly techniques, such as lamination, vacuum bonding, and UV curing.
6. Experience with failure analysis techniques, including FTIR, SEM, and environmental aging tests.
7. Understanding of polarizers, anti-reflective coatings, and light diffusion films.
8. Experience with liquid optical bonding (LOCA) and optically clear adhesives (OCA) for high-resolution displays.
9. Knowledge of roll-to-roll processing, plasma treatment, and precision coating techniques.
10. Exposure to ISO and ASTM standards for optical adhesive and film testing.
11. Strong knowledge with Microsoft Office (Excel, PowerPoint)

Work Environment:
1. Hands-on lab and manufacturing environment with optical testing, bonding, and metrology equipment
2. Collaboration with cross-functional teams, including R&D, Manufacturing, and Quality Engineering
3. Some travel may be required to supplier or production sites for material evaluation and process support
