Key learning opportunities for this job

Candidates can expect deep immersion into the complexities of CSRD (Corporate Sustainability Reporting Directive) within a diversified infrastructure conglomerate. This environment offers a unique chance to see how sustainability metrics apply across vastly different sectors, from renewable energy to public transportation. There is significant exposure to advanced ESG controlling tools and methodologies. The company emphasizes internal training, offering specifically targeted educational programs that help specialists stay ahead of the curve in non-financial auditing and reporting standards.

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

The ideal candidate holds a degree in Business Administration or Sustainability and possesses a strong background in financial or sustainability controlling. Professional certifications such as the ESG Professional or Sustainability Reporting Specialist from ÖCI are highly valued and indicate the necessary technical depth. Analytical precision and high Excel proficiency are essential for handling complex data sets. Equally important is a communicative personality; you must be able to translate technical ESG requirements into clear instructions for various internal departments that may not have a background in reporting.

Advice to stand out and make a successful application

Focus your application on your technical understanding of the NaBeG and CSRD. The hiring team is looking for someone who doesn't just know the acronyms but understands the practical implications of implementing these frameworks in a large-scale corporate environment. If you have experience in interdisciplinary project management, highlight it. Demonstrating how you have previously bridged the gap between finance departments and sustainability teams will set you apart as a candidate who can navigate the complex structure of a municipal utility group.

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

The role focuses heavily on transparency and accountability within the city's green transition. You will be the gatekeeper for data related to decarbonization efforts, resource efficiency, and social responsibility metrics that define the group's 'klimafit' strategy. Specifically, you will likely work on the EU Taxonomy alignment of major infrastructure projects. This ensures that the massive investments made by Wiener Stadtwerke in public transit and energy networks are correctly classified and reported as sustainable activities to investors and regulators.

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

One of the primary challenges is data harmonization across multiple diverse subsidiaries. Ensuring that a transit company and a funeral service provider report consistent and comparable ESG data requires high attention to detail and diplomatic persistence. The rapidly changing regulatory landscape in the EU also presents a challenge. You will need to stay agile and constantly update internal processes to keep pace with new ESRS interpretations and reporting requirements without disrupting the quarterly reporting cycle.

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

A typical day might involve a morning session reviewing KPI submissions from various business units, followed by a meeting with the IT department to optimize the ESG reporting software. You might spend time analyzing Excel models to ensure EU Taxonomy compliance for a new wind farm project. In the afternoon, you could be drafting internal guidelines for ESRS data collection or preparing a briefing for senior management on the latest regulatory developments. The day is a mix of deep analytical work and cross-functional coordination.

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

Growth in this role often looks like specialization in ESG strategy or a move into senior controlling management within the group. The high visibility of ESG reporting makes this a strategic position with exposure to executive decision-making processes. There are also opportunities for internal mobility (Jobtausch), allowing you to gain insights into different sectors of the group. This breadth of experience is invaluable for anyone aiming for a leadership role in sustainable corporate governance.

The main stakeholders you might be interacting with

You will interact extensively with the Group Sustainability Team and Finance Department to align non-financial and financial reporting. External auditors are also key stakeholders during the year-end reporting process. Within the subsidiaries, you will work closely with local ESG coordinators and operational managers. Your role is to support them in data collection while providing the necessary oversight to ensure group-wide consistency.
