This role involves orchestrating the implementation of corporate social responsibility projects across the French operations of a major retail leader. You will take ownership of tracking sustainability performance indicators, specifically focusing on product offer transformation and carbon trajectory goals. By coordinating closely with purchasing and marketing departments, you ensure that group-level ESG ambitions translate into tangible operational shifts in store inventory and supplier standards.

Working within the retail sector offers a unique opportunity to influence decentralized consumption habits on a massive scale. This position is critical because it bridges the gap between high-level group strategy and the technical realities of product lifecycles and energy efficiency in the home improvement market. It is an opportunity to directly impact the environmental footprint of industrial goods and consumer choice in the DIY sector.

This suits someone who is currently in their final year of an engineering or master’s degree and possesses a highly analytical mindset. You should be comfortable navigating complex data sets and demonstrating the interpersonal influence required to move cross-functional teams toward shared sustainability milestones.

Preguntas frecuentes

What are the main missions and responsibilities of this role?

The successful candidate will be responsible for monitoring and driving CSR performance across the organization. This involves a deep dive into the carbon trajectory of the company, specifically tracking and reporting on indicators that reflect the sustainability of the product offer. You will act as a central hub for data, ensuring that the strategic ambitions set by the Kingfisher group are measured accurately at the local level. Collaboration is a major pillar of this role. You will co-animate action plans with the Purchasing and Marketing departments to integrate sustainability criteria into their daily operations. Furthermore, you will be tasked with preparing essential data for regulatory declarations, such as the Carbon Border Adjustment Mechanism (MACF), ensuring the company remains compliant with evolving European environmental legislations.

Key learning opportunities for this job

This apprenticeship offers an immersion into the complexities of retail ESG reporting and the practical application of the Carbon Border Adjustment Mechanism (MACF). You will gain hands-on experience in how a multi-national group translates high-level climate commitments into local procurement policies and product selection processes. Beyond technical data management, you will develop strong skills in change management within a corporate setting. Navigating the interests of diverse departments like finance, legal, and commercial operations will provide a rare insight into the organizational dynamics required to implement large-scale environmental transitions.

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

The ideal candidate is a student in their 5th year of a Master's degree, preferably from an engineering school or a specialized university program focused on sustainable development or project management. A robust mastery of Excel and the broader Office suite is non-negotiable, as the role relies heavily on data analysis and KPI tracking. Strong interpersonal and influence skills are essential, as you will need to convince internal stakeholders of the necessity of CSR initiatives. Candidates with a technical understanding of habitat-related issues—such as energy efficiency or sustainable materials—and prior experience in life cycle assessment (LCA) or carbon footprinting will be highly regarded.

Advice to stand out and make a successful application

To stand out, highlight any experience you have with technical sustainability tools like carbon footprint software or LCA databases. Since the role involves significant interaction with the Kingfisher group, demonstrating your ability to work in a multi-level corporate environment will be a major advantage. Show that you understand the specific challenges of the DIY and retail industry. Researching Castorama's current 'sustainable home' initiatives and mentioning how your analytical skills can help improve their 'Green' product percentage will demonstrate a proactive and business-aligned mindset.

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

The role is primarily focused on the decarbonization of the supply chain and the environmental impact of the products sold in-store. You will work on the 'offer' side of CSR, which means looking at how products are sourced, their durability, and their total carbon impact from production to disposal. Additionally, there is a strong focus on regulatory transparency and reporting. By contributing to the Kingfisher CSR report and managing regulatory data, the role ensures that the company’s environmental claims are backed by rigorous data and align with group-wide transparency standards.

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

One of the primary challenges will be the transversal nature of the projects. You will need to solicit data and commitment from departments whose primary KPIs are often financial or commercial, requiring you to find common ground between sustainability and business profitability. Another challenge is the technical complexity of the reporting. Managing carbon data across a vast catalog of home improvement products requires meticulous attention to detail and the ability to handle evolving regulatory frameworks without losing sight of the broader strategic goals.

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

A typical day might begin with analyzing performance dashboards to track the progress of sustainable product lines. You might then transition into a meeting with the Purchasing team to review supplier environmental criteria or discuss the implementation of new group-level RSE policies. Your afternoon could involve synthesizing data for the next Kingfisher group meeting or preparing technical documentation for environmental compliance. The role is a mix of solitary analytical work and highly collaborative coordination, often requiring you to switch between deep data dives and cross-departmental communication.

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

This position serves as an excellent launching pad for a career in ESG management within large international corporations. Successful completion of this apprenticeship could lead to full-time roles such as a CSR Project Manager, ESG Analyst, or Sustainable Procurement Specialist. Because the role interacts with the Kingfisher group level, it provides high-level visibility that is rare for entry-level positions. This exposure can open doors to international career paths within the broader group or other major players in the European retail sector.

The main stakeholders you might be interacting with

You will frequently interact with the Marketing and Purchasing teams, where you provide the RSE expertise needed to shape the product offer. Locally, you will report to the CSR department while maintaining a strong functional link with project owners across the French headquarters. Externally and at the group level, you will be a Point of Contact for Kingfisher plc's sustainability experts. You may also interact with external consultants or regulatory bodies when preparing mandatory environmental disclosures and ensuring the accuracy of carbon reporting data.
