As a central figure in the external reporting team, you will own the end-to-end preparation of environmental and ESG disclosures. This means translating complex performance data into clear, audit-ready narratives for the annual report and external indexes. You will not just report numbers; you will drive the integrity of non-financial information across a global matrix organization, ensuring every claim is backed by robust internal controls.

Working for a global leader in beverage manufacturing, your work ensures that the company’s ambitious water, carbon, and waste commitments are transparently communicated to investors and regulators. In an era of tightening CSRD and SEC mandates, this role is the safeguard that prevents greenwashing and builds genuine market trust in the brand’s long-term environmental stewardship.

This suits someone who possesses a sharp analytical mind and the interpersonal gravitas to influence senior stakeholders across finance and sustainability functions without having direct authority.

Preguntas frecuentes

What are the main missions and responsibilities of this role?

The primary mission is to own the preparation of ESG-related disclosures within the Annual Report and Environmental Reporting Index (ERI). You will be responsible for ensuring that all environmental data is accurate, consistent, and compliant with evolving international standards. Beyond just drafting reports, you will act as the key liaison with external auditors, resolving queries and managing the assurance process for non-financial information. You will also partner with functional owners to establish and monitor internal controls over ESG data points. Strategically, you will identify opportunities to enhance reporting processes and ensure that the Filing Assurance Committee is fully aligned with management actions and regulatory requirements.

Key learning opportunities for this job

You will gain deep expertise in global sustainability frameworks such as TCFD, SASB, and GRI, while navigating the practical implementation of emerging EU and US reporting regulations. This is a front-row seat to how a FTSE 100 leader manages non-financial compliance. You will also develop high-level proficiency in advanced reporting tools like Workiva and learn the intricacies of matrix influence. The role offers exposure to how environmental metrics, like carbon and water usage, are integrated into financial risk assessments and investor communications.

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

The ideal candidate brings at least five years of experience in ESG reporting or environmental finance, backed by a degree in Business, Finance, or Environmental Sciences. You should have a proven track record of handling complex data assurance processes and working with major accounting firms. Technical knowledge of environmental metrics like Scope 3 emissions or water replenishment is highly valued. Equally important is your ability to navigate a matrixed environment, requiring strong interpersonal skills to drive results through colleagues over whom you have no direct authority.

Advice to stand out and make a successful application

Focus your application on your technical understanding of data controls and assurance. Highlight specific examples where you have successfully managed an external audit process or implemented a new disclosure framework in a large corporate setting. Since this is an individual contributor role requiring high influence, use your cover letter to demonstrate stakeholder management prowess. Show that you understand the unique reporting challenges faced by the beverage industry, particularly regarding supply chain transparency and resource scarcity.

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

This role sits at the intersection of performance and transparency, focusing heavily on water stewardship and carbon reduction reporting. You will be documenting the progress of the company's 'Society 2030' goals through rigorous data tracking. You will also focus on circularity and waste management metrics. The role ensures that the environmental impact of producing 200+ global brands is disclosed in a way that satisfies both regulatory bodies and ESG-focused institutional investors.

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

The biggest challenge will be influencing across functions to ensure timely and accurate data delivery from various global teams. As an individual contributor, you must rely on your expertise and communication skills to hold others accountable. Additionally, keeping pace with the rapidly changing regulatory landscape (like CSRD) across different jurisdictions while maintaining a consistent global narrative will require constant vigilance and the ability to simplify complex technical requirements for non-experts.

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

A typical day involves a mix of reviewing technical data sets and attending cross-functional meetings with the sustainability and compliance teams. You might spend the morning coordinating with external auditors to close out queries on environmental metrics. In the afternoon, you could be drafting narrative disclosures for the Annual Report or meeting with the External Reporting Lead to align on the presentation of ESG performance for an upcoming results announcement. It is a cycle of data validation, stakeholder consultation, and strategic drafting.

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

This role offers significant visibility to senior leadership and the Audit Committee, providing a platform for potential moves into Senior ESG Management or specialized Compliance leadership roles. The global nature of the firm facilitates lateral moves into different regions or functions. You will build a specialized skill set in ESG assurance, which is currently one of the most in-demand areas of corporate finance and sustainability. This expertise positions you well for future Director-level roles in Corporate Sustainability or Investor Relations.

The main stakeholders you might be interacting with

You will interact daily with the External Reporting and Sustainability teams to align on data and messaging. You also work closely with the Compliance and Assurance leads to ensure internal controls are functioning correctly. Externally, your primary contact will be third-party auditors (PwC) during the assurance cycle. You will also provide critical information to the Filing Assurance Committee and senior executives who oversee the company's public market disclosures.
