A Day in the Life

Reporting to the head of the "Environmental Impact Assessment" team, you will operate at the heart of a multidisciplinary ecosystem. Your daily life will involve embodying technical expertise and data mastery to serve the Group's sustainability strategy. You will act as a key interface between the internal needs of R&I and external expert partners, ensuring that LCA science translates into concrete business orientations.

Your Missions:

1. Methodology Guardian& Value Internalization:

• Act as one of the LCA and product carbon footprint (PCF) methodological referents within the department for the ingredients and bioresources (feedstocks) of the L'Oréal portfolio.
• Guarantee the reliability of impact data used for extra-financial reporting (notably carbon), the eco-design process of our formulas, and internal studies on the Group's sustainability challenges.
• Internalize added value: analyze and synthesize key concepts shared by external providers to enrich internal expertise and build our collective knowledge base.

2. Leading and connecting:

• Agilely lead technically a large portfolio of impact studies and contribute to prioritizing needs and intersecting the Group's major environmental challenges with operational reality (volumes, material criticality).
• Translate business needs into technical data for consultants, perform critical analysis of their results, and transform them into clear, actionable strategic recommendations.
• Support internal partners in interpreting results and evaluate the environmental relevance of new ingredients compared to current portfolio benchmarks.

3. Data Governance & Digital Ecosystem:

• Guarantee the quality, traceability, and consistency of environmental data (used for carbon, water, and biodiversity needs) generated by our team and partners.
• Optimize data collection and management processes by bridging the gap between business needs and IT teams (eco-design tools, databases).
• Continue developing the interface between feedstocks, ingredients, and raw materials for a multi-level understanding of impact.

4. Methodological Development:

• Transform scientific and regulatory monitoring into levers for action: contribute to reflections on the evolution of our methods to anticipate future framework changes.
• Participate in expert working groups to represent L'Oréal's technical vision.

• Education: Engineering degree or Master's (Bac+5) in Environment, Chemistry, or Agronomy.
• Technical Expertise: Mastery of LCA concepts, as well as associated software and databases (SimaPro / ecoinvent). A good understanding of carbon accounting frameworks is an asset.
• Scientific Foundation: Knowledge of organic chemistry is essential to understand the nature of our ingredients and challenge data.
• Experience: Minimum of 3 years of experience, preferably 5 years, in an industrial sector or consulting firm.

• Soft Skills
  • Agility & Strategic Perspective: Strong intellectual agility allowing you to juggle multiple subjects and connect technical points to global strategic issues (climate, biodiversity, resources).
  • Synthesis & Pedagogy: You know how to simplify complexity and communicate clearly with non-expert stakeholders.
  • Project Leadership & Proactivity: You take ownership of your topics, anticipate roadblocks, mobilize the right people, and drive initiatives through to delivery.
  • Data Mindset: A marked appetite for database management and IT tools. Operational rigor is second nature to you.
  • Collaboration: You enjoy working in networks and know how to navigate a complex organization where success depends on collective intelligence rather than solitary execution.
• Languages: Native-level or bilingual French; Fluency in English is mandatory (international and scientific context).
