Assistant manager Business Development

SEKISUI S-LEC

Your Mission

Imagine walking into a design review with a premium automotive brand and presenting a prototype of laminated glass featuring new innovations. You sparked the idea months earlier during a networking lunch, guided it through rapid PDCA sprints with our EU and Japan R&D teams, developed proof-of-concept parts with a glass partner, and are now leading the project towards business nomination.
That’s the daily arc of this role.

  • Customer management: influence across design, NVH and glazing; pitch use cases; and nurture the project pipeline until the start of production.
  • Strategy and research: track megatrends in automotive or architectural glazing, such as EV roofs, acoustic comfort, solar control and displays. Frame business cases and align with the R&D, Sales, Technical Service and Global Marketing teams.
  • Action and execution: lead prototyping, external partnerships, vehicle tests and digital and conference promotions that prove value quickly.

Your goal is to convert marketing curiosity into business that showcases the multifunctional edge of S-LEC™ film, thereby extending our leadership in laminated glass technology.

Who We Are: “Make the NEW” with the World’s PVB Interlayer Leader for Laminated Glass

For over 60 years, SEKISUI S-LEC has been at the forefront of PVB interlayer film technology, transforming glass into a platform for safety, design and sustainability. Today, our S-LEC™ film is used in laminated glass in automotive and architecture for various purposes, such as blocking UV rays, reducing noise, preventing solar heat gain, enabling clear head-up display images and creating stylish colour gradients.

Our action slogan, “Make the NEW,” captures how we work: fast experimental loops, cross-border collaboration and the courage to connect ideas, people and industries.
Join a team where Service, Speed and product Superiority (the 3 S’s) are more than words – they are the KPIs we measure every prototype, customer visit and market analysis against. Here, business development is not a hand-off function; it is the engine that drives “the NEW” from first sketch to serial production.

  • Shape strategy: create business plans with internal colleagues and track progress, making early adjustments if necessary.
