Working within a multi-sector industrial group, you will take charge of the end-to-end data lifecycle for the organization’s ESG performance. This involves designing reporting tools, calculating carbon footprints across all three scopes, and performing Life Cycle Assessments (LCA) for chemical and biotech products. You will bridge the gap between technical data and strategic decision-making by translating complex metrics into actionable insights for the executive committee.

This role is a catalyst for the group’s ecological transition, moving beyond simple compliance to drive decarbonization in high-impact sectors like water treatment and pharmaceuticals. By integrating ESG criteria into procurement and manufacturing processes, you will help modernize the sustainability framework of a global industrial player. It is a unique chance to influence the environmental footprint of essential industrial solutions at an international scale.

This suits someone who possesses a sharp analytical mind and an engineering or business background, combined with technical mastery of Excel and a passion for industrial sustainability.

Job-FAQs

What are the main missions and responsibilities of this role?

The core of this role involves structuring and consolidating ESG data across more than 50 international subsidiaries. You will be responsible for the entire reporting cycle, from defining data collection models for energy and waste to ensuring the reliability of information for the annual sustainability report. This includes developing dashboards for the Executive Committee to track decarbonization progress. Beyond general reporting, you will manage carbon accounting and product life cycle assessments. This means calculating Scopes 1, 2, and 3 emissions and identifying specific reduction levers within the group's chemical and biotech processes. You will also lead the ESG assessment of strategic suppliers to integrate sustainability into the purchasing department's decision-making.

Key learning opportunities for this job

You will gain deep expertise in CSRD compliance and ESRS standards, as you will be at the forefront of the group's regulatory adaptation. This is an excellent environment to master advanced carbon accounting methodologies and Product Carbon Footprint (PCF) analysis, which are highly sought-after technical skills in the industrial sector. Additionally, you will learn how to digitalize ESG processes within a global industrial ERP system like Sage X3. Exposure to diverse sectors—from fragrance creation to pharmaceutical active ingredients—will provide a broad perspective on how sustainability challenges differ across chemical and biological manufacturing environments.

How does the ideal candidate look like (experience, skills)?

The ideal candidate holds a Master’s degree from an engineering or business school with a specialization in data science or sustainable development. You should have 1 to 3 years of experience, ideally in a consulting firm or a corporate ESG department, where you have already handled carbon footprinting or extra-financial reporting. Technically, you must be an Excel expert, proficient with Power Query and database management, as the role requires cleaning and analyzing large volumes of complex data. Fluency in both French and English is essential due to the international nature of the group's subsidiaries and global supply chain.

Advice to stand out and make a successful application

To stand out, demonstrate your ability to handle complex industrial data. In your cover letter, don't just mention your interest in sustainability; explain a specific instance where you successfully used data analysis to solve a problem or identify an environmental impact. Analytical rigor is the top priority for this team. Familiarize yourself with the One Health approach and Proxis Développement’s specific business units. Showing that you understand the intersection of specialty chemicals, water preservation, and ESG regulations like CSRD will prove that you are ready to hit the ground running in their specific regulatory context.

What aspects of the company's sustainability is this role likely to focus on?

The role focuses heavily on decarbonization and climate strategy. You will spend significant time refining the group's carbon trajectory by analyzing emission hotspots across the supply chain. This includes a strong focus on Scope 3, specifically regarding raw material sourcing and the end-of-life of chemical products. There is also a significant sustainable procurement component. You will be tasked with soliciting and analyzing ESG data from suppliers to ensure the group's environmental commitments are reflected in its purchasing choices. This ensures that sustainability is embedded into the group's core industrial operations rather than existing as a separate function.

What are the main challenges someone in this role might face?

One of the primary challenges will be the harmonization of data across many different subsidiaries with varying levels of ESG maturity. Convincing local teams to provide accurate and timely data requires both pedagogical skills and great persistence. You will need to build trust while maintaining high standards for data quality. Another challenge lies in the technical complexity of LCAs in the chemical and biotech fields. Balancing the scientific precision required for these assessments with the operational need for simplified reporting for the COMEX will require a strong sense of priority and excellent synthesis skills.

How could a typical day look like for someone in this position?

A typical day might begin with a meeting with the Purchasing or Quality departments to discuss the integration of new ESG criteria into the supplier onboarding process. You might then spend several hours in Excel or Power Query, consolidating energy consumption data from a French subsidiary and a foreign biotech plant to update the carbon dashboard. In the afternoon, you could work on a Life Cycle Assessment for a new fragrance ingredient, researching emission factors and collaborating with the technical teams. The day often ends with regulatory monitoring or drafting sections of the sustainability report to ensure compliance with the latest European directives.

What are the opportunities for professional growth and development in this role?

As a junior analyst in a growing group, you have a clear path toward becoming an ESG Manager or a Decarbonization Lead. The transverse nature of the role provides high visibility, meaning success in this position could lead to strategic roles within the Finance or Operations departments as they become more integrated with sustainability goals. The group’s entrepreneurial culture encourages proactivity. If you successfully implement new digitalization tools for reporting, you could eventually lead the group's entire ESG data strategy or specialize in high-level environmental engineering and life cycle management for the chemical industry.

The main stakeholders you might be interacting with

You will report directly to the Group ESG Director while maintaining a close functional relationship with the Purchasing and Quality Directors. These interactions are crucial for embedding ESG metrics into the group’s operational heart. Externally, you will be the point of contact for strategic suppliers regarding their sustainability performance. Internally, you will interact with subsidiary managers across the globe and collaborate with the Legal department and the ESG Executive Committee (COMEX) to ensure the group’s strategy aligns with international regulations.
