As a Sustainability Officer at BESIX, you will take on a strategic role within a compact group-level team. Your daily focus centers on translating high-level ESG ambitions into measurable actions across an international project portfolio. You will participate in refining the corporate sustainability roadmap, developing robust KPIs, and ensuring that circularity and decarbonization efforts transition from concept to operational reality.

This position is essential because it bridges the gap between global regulatory requirements like the CSRD and the heavy industrial reality of construction. By embedding ESG principles into the firm’s governance and internal networks, you directly influence how iconic infrastructure projects are designed and built. You are the catalyst for a long-term legacy, steering thousands of colleagues toward more responsible construction practices.

This suits someone who possesses a strong analytical mindset and feels comfortable navigating a complex, multicultural environment. You should have a talent for building internal networks and the professional maturity to communicate sustainability objectives to diverse stakeholders, from on-site engineering teams to group executives.

Perguntas frequentes da vaga

What are the main missions and responsibilities of this role?

The primary mission is to translate the Group's sustainability strategy into actionable frameworks across international operations. You will be responsible for the continuous refinement of the sustainability roadmap, ensuring that key performance indicators (KPIs) and digital dashboards accurately reflect the company's progress toward its long-term goals. On the regulatory side, you will lead the implementation of CSRD and EU Taxonomy requirements. This includes managing double materiality assessments and ensuring data governance is robust enough for external auditing. You will also build and support a global internal sustainability network, fostering a culture of accountability across different business units.

Key learning opportunities for this job

You will gain deep expertise in navigating the CSRD and ESRS frameworks within a high-stakes, industrial context. Given the multidisciplinary nature of BESIX, you will learn how sustainability intersects with complex engineering, project finance, and international maritime works. There is also a significant opportunity to develop skills in change management and corporate governance. Working at a group level provides exposure to how large-scale enterprises adapt their business models to meet global environmental targets, offering a front-row seat to the evolution of the construction industry.

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

The ideal candidate holds a Master's degree in a relevant field like Engineering, Environmental Sciences, or Economics, paired with at least five years of corporate sustainability experience. A background in construction or infrastructure is highly valued, as it ensures you understand the technical constraints of the industry. You should be a trilingual or highly proficient communicator in English, Dutch, and French. The role requires a blend of high-level analytical skills for reporting and soft skills for driving cultural change among diverse, international teams.

Advice to stand out and make a successful application

Focus your application on your technical understanding of ESG reporting frameworks and your ability to manage complex data environments. Highlight any specific experience you have with international project-based organizations, as BESIX operates in a highly decentralized and globalized manner. In your cover letter, demonstrate how you have previously bridged the gap between corporate strategy and operational execution. Highlighting your experience with the CSRD or circular economy initiatives in an industrial setting will help you stand out to the recruiting team.

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

The role focuses heavily on the Environmental and Governance pillars of ESG. You will likely spend significant time on decarbonization strategies and circular construction methods, which are critical for the construction sector's transition to a low-carbon economy. From a governance perspective, the focus is on data transparency and ethical operations. Ensuring that sustainability is not just an add-on but an integrated part of the risk management and decision-making process is a core component of the position.

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

One of the main challenges is standardizing sustainability data across 27+ countries and multiple business units. Collecting accurate, auditable information from varied project sites requires significant persistence and technical coordination with ICT and operational teams. You may also face the challenge of driving cultural change in a traditional industry. Overcoming skepticism and ensuring that sustainability remains a priority alongside tight project deadlines and financial constraints requires both diplomacy and strong leadership.

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

A typical day might begin with a coordination meeting with the CSRD project team to review data collection progress. You could then transition to a briefing session with operational managers in the Middle East or Australia to discuss the implementation of new carbon reduction KPIs on a specific infrastructure project. In the afternoon, you might switch to analytical work, refining reporting dashboards or preparing a presentation for the executive committee. Your day often concludes with stakeholder outreach, perhaps corresponding with external auditors or specialized NGOs regarding the company's ESG performance.

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

There are clear paths toward senior management roles within the sustainability department or lateral moves into strategic business development. As ESG becomes more central to securing large-scale concessions and infrastructure projects, your expertise will be highly visible to top leadership. BESIX also offers international career opportunities. Given the group's presence on four continents, there is the potential to lead regional sustainability initiatives or specialize in specific areas like sustainable finance or green engineering transition.

The main stakeholders you might be interacting with

You will interact frequently with group executives and business unit heads to align sustainability efforts with commercial goals. On the technical side, you will collaborate closely with the Engineering, Legal, and ICT departments to ensure data integrity and technological support for ESG reporting. Externally, you will be the point of contact for auditors, rating agencies, and regulatory bodies. You will also represent BESIX in industry forums, ensuring the company stays at the forefront of sustainable construction practices and maintains its reputation among clients and local communities.
