Assistant Demand Planning Manager

Bangkok, Thailand

The engine behind the beauty.

Getting 7 billion products to 150 countries is a complex puzzle. You won’t just be tracking shipments. You’ll be working with real-time forecasting, AI inventory systems, and automated warehouses across 180 global sites. Your focus? Moving products through 8 distribution channels efficiently, while figuring out how to strip carbon out of the entire process. It’s highly technical, the pace is fast, and the expectations are high. If you like solving real operational problems at scale, you'll fit right in.

Skills you'll sharpen here

  • Global problem-solving
  • Data-driven decision making
  • Cross-functional collaboration
  • Sustainable practices
  • Agile project management
  • Leadership & influence

As well as these, L'Oréal employees are upksilled in AI fluency, data fluency, and critical thinking.

Inside the operation

  • You’ll work in a fast-paced

    'test and learn' environment where you are empowered to make high-stakes decisions in real time. We celebrate entrepreneurship, and agility is how we navigate the market.

  • You won't just manage flows - you’ll pioneer the future of distribution.

    Expect to work with AI, Big Data, and advanced robotics to build a predictive, ultra-connected supply chain.

  • Your mission is dual:

    drive economic performance while taking radical environmental responsibility. From running carbon-neutral warehouses to designing sustainable packaging loops, you’ll actively reduce our planetary footprint.

  • You’ll accelerate your career with a global leader in supply chain sophistication.

    We consistently rank in the Gartner Top 10 worldwide for our innovation and operational mastery.
