This internship puts you at the center of the operational rollout of the CSR strategy for a leading satellite services company. Working closely with the Ethics and CSR officer, you’ll actively help structure the group’s carbon trajectory and strengthen its responsible purchasing policy.

The role is unique because it links the technical rigor of ISO 14001 certification to the creativity needed to raise employee awareness. Working for a company whose core business is Earth observation, you directly help align internal practices with its broader environmental mission.

This suits someone who is a Bac+4/5 student with an initial specialization in CSR, looking for a versatile experience, with strong initiative and a desire to see the concrete impact of their communication and project management work.

This includes identifying key emission sources and proposing reduction trajectories. You will also play a critical role in responsible purchasing by developing evaluation questionnaires and environmental clauses for suppliers. Additionally, you will support the ISO 14001 certification process for the French sites by documenting environmental management systems and defining continuous improvement plans.

Key learning opportunities for this job

This position offers deep technical exposure to the ISO 14001 standard and environmental management systems in a complex, high-tech industrial environment. You will gain hands-on experience in carbon accounting and the practical implementation of sustainable procurement policies. Beyond technical skills, the intern will develop strong stakeholder engagement abilities by translating complex ESG concepts into accessible communication materials for an international workforce and organizing internal awareness events.

The ideal candidate is currently pursuing a Master's degree in CSR or Environmental Management and demonstrates a sincere passion for sustainability challenges. A solid understanding of the ISO 14001 framework is highly valued. Key soft skills include rigor, organization, and initiative. You should be comfortable working autonomously while being a collaborative team player. Proficiency in Excel and English is necessary to handle international data and reporting.

Advice to stand out and make a successful application

To stand out, emphasize any experience you have with environmental standards or carbon reporting tools. Demonstrating an interest in how space technology serves environmental protection will show alignment with CLS Group's core mission as a 'société à mission'. Ensure your application showcases your writing skills, as internal communication and documentation are significant parts of the role. Mention any specific projects where you took the initiative to launch a sustainability or awareness campaign.

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

The role bridges the gap between the company's external mission (Earth observation) and its internal operations. You will focus heavily on environmental compliance through the ISO 14001 roadmap and decarbonization strategies. There is also a significant focus on Responsible IT and biodiversity, reflecting the nature of a data-driven space company looking to minimize its digital and physical footprint.

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

The most significant challenge will be coordinating efforts across diverse teams (Quality, HSE, Purchasing, and HR) to gather data and implement new processes. Balancing technical documentation with creative communication tasks requires high adaptability. You may also face the challenge of standardizing practices across 41 international sites, navigating different local regulations and cultural approaches to sustainability.

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

A typical day might begin with a meeting with the HSE team to review the environmental aspect register for the ISO certification. You might spend the afternoon drafting a briefing pack on eco-design or digital sobriety for the group's engineers. Later, you could be analyzing responses from a supplier survey to update the responsible purchasing scorecard or brainstorming ideas for the next internal CSR awareness workshop hosted on the company intranet.

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

Interns at CLS are given real responsibilities, providing a strong foundation for a career as a CSR Project Manager or Environmental Consultant. The exposure to international operations and high-level certifications is a significant career accelerator. Given the group's growth and the increasing importance of ESG compliance, successful interns may see opportunities for further collaboration or gain a competitive edge in the green job market across the aerospace and environmental sectors.

The main stakeholders you might be interacting with

You will work most closely with the Ethics and CSR Office, but your role is highly transversal. You will frequently interact with the Quality and HSE departments for certification projects. Externally, you will engage with suppliers to enforce CSR clauses. Internally, your audience includes all 1,200 employees globally as you drive engagement through articles, workshops, and educational materials.
