Candidati a questo ruolo →

Join the corporate social responsibility team to support the rollout of a group-wide sustainability strategy. You will be centrally involved in the annual reporting cycle, moving from raw data collection to the creation of meaningful content that tracks progress against environmental and social targets. Your work helps translate complex data sets into actionable summaries for leadership decision-making.

Working within the electrical solutions sector means your efforts directly support the energy transition. By refining how the group reports on its carbon footprint and circular economy initiatives, you ensure transparency for a company that powers modern infrastructure. This role is a rare chance to bridge the gap between high-level ESG frameworks and the operational reality of global manufacturing.

This suits someone who is pursuing a Master’s degree in environmental engineering or sustainability and possesses a sharp analytical mindset. You should be comfortable navigating large Excel sheets and be eager to contribute your own voice to an international, mission-driven team.

FAQ del ruolo

What are the main missions and responsibilities of this role?

As an intern, your core responsibility is to support the Corporate Social Responsibility Manager in the execution of the group's sustainability agenda. You will dive deep into the annual reporting process, which involves identifying data owners across different departments and ensuring the accuracy of the information collected. Beyond data gathering, you will be tasked with transforming these figures into narrative content for the sustainability report. You will also perform high-level analysis on data sets to provide the team with summaries that support strategic decision-making and group-wide environmental monitoring.

Key learning opportunities for this job

This position offers a front-row seat to the implementation of CSRD-aligned reporting within a major industrial player. You will learn how to manage complex environmental data and translate it into a narrative that meets international reporting standards. The role provides hands-on experience with environmental KPIs and the methodology behind carbon footprinting for large-scale operations. Mentorship is a central pillar of this experience, as you will be reporting to an experienced CSR Manager. Additionally, you will gain exposure to the TAI Community, which offers a broader networking platform to learn from other interns and apprentices across the global organization.

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

The team is looking for a student currently enrolled in a Master's program (Bac +4/5) specifically focused on Sustainability or Environmental Engineering. Because the role is based in an international corporate environment, total fluency in English is mandatory for success. Technical proficiency in Microsoft Excel is critical, as you will spend significant time cleaning and analyzing data. Beyond technical skills, the ideal intern demonstrates personal initiative and a solution-oriented mindset, showing a high level of attention to detail which is vital for accurate ESG disclosures.

Advice to stand out and make a successful application

To stand out, you should demonstrate that you have thoroughly researched the company’s current sustainability performance. Mentioning specific themes or projects from their 2025 Annual Report in your introduction will show a high level of engagement and motivation. Keep your application concise; the team prefers a tailored CV that highlights analytical projects or previous environmental data experience over a long cover letter. Be clear about your availability for the full 6-month duration starting in late 2026 to ensure alignment with their project cycles.

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

The role focuses heavily on ESG transparency and the measurement of environmental impact across the value chain. Given the company's position in electrical manufacturing, you will likely encounter topics related to energy transition, circular economy models for hardware, and decarbonization of production facilities. You will also contribute to the 'Social' pillar of ESG by assisting in the communication of the group's corporate values and social initiatives through the formal reporting structure.

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

The most significant challenge will be the complexity of data collection in a large organization. You may need to follow up with various stakeholders across different departments who have competing priorities, requiring professional persistence and excellent communication skills. Another challenge lies in the accuracy and integrity of the data. As these reports are often subject to audit or regulatory scrutiny, ensuring that every data point is verified and consistent across several hundred pages of reporting is a demanding task.

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

A typical day might begin with a team meeting to discuss the progress of the reporting cycle, followed by several hours of data auditing in Excel. You would communicate via email or video calls with site managers to clarify specific environmental metrics or social statistics. In the afternoons, you might shift towards content creation, drafting sections of the sustainability report or designing visual summaries of data for internal presentations. You also have the flexibility to participate in networking events hosted by the internal trainee community.

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

This internship is designed as a potential talent pipeline; the company emphasizes its 'Happy Trainees' certification and high recommendation rate. A successful internship can lead to future full-time opportunities within the sustainability or QEHS departments as the group expands its ESG capabilities. You will build a professional network within the TAI Community that spans multiple countries, providing a strong platform for future career moves within the electrical engineering and green technology sectors.

The main stakeholders you might be interacting with

Your primary interaction will be with the Corporate Social Responsibility Manager, who serves as your mentor. You will also collaborate with the wider CSR team and the TAI Community of interns and apprentices. Externally, you will interact with department heads across manufacturing, HR, and facilities to gather data. Although you are based in a specific location, the nature of the reporting role means you will likely communicate with stakeholders across different international office hubs.
