This role acts as a bridge between corporate finance and environmental stewardship, overseeing the framework that translates Mars’ sustainability performance into rigorous, audit-ready data. You will take ownership of the global sustainability reporting calendar, defining the internal controls and documentation needed to ensure compliance with emerging international regulations. By partnering with segment leaders and controllership teams, you will transform raw social and environmental metrics into high-stakes corporate disclosures.

At a time when global transparency mandates like CSRD are reshaping the business landscape, this position ensures that one of the world’s largest private food companies remains accountable to its sustainability promises. You are not just tracking numbers; you are building the governance architecture that proves the company’s Five Principles are active and measurable across its vast global footprint. This creates the trust necessary for long-term investments in sustainable sourcing and social impact.

This suits someone who possesses a strong background in accounting or risk management and thrives when bringing structure and process to complex, evolving regulatory environments.

Job FAQs

What are the main missions and responsibilities of this role?

The primary mission involves establishing a robust Sustainability Reporting for Finance framework. You will be responsible for defining the internal processes and controls that ensure Mars complies with mandatory global reporting requirements. This includes leading activity reporting and creating supporting documentation that meets the high standards of corporate governance. Key responsibilities also include managing the global reporting calendar and coordinating with various business segments. You will act as the technical subject matter expert for sustainability disclosures, ensuring that data across environmental, social, and governance pillars is accurate, timely, and aligned with external regulatory expectations.

Key learning opportunities for this job

Candidates will gain unparalleled exposure to the implementation of CSRD (Corporate Sustainability Reporting Directive) within a massive, privately-held global organization. This provides a front-row seat to how a major CPG firm transitions from voluntary to mandatory ESG reporting frameworks. Beyond regulatory knowledge, you will likely enhance your expertise in COSO and SOX-style controls applied to non-financial data. The role also offers access to Mars University, providing structured professional development to bridge gaps between traditional finance and modern sustainability metrics.

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

The ideal candidate brings over 8 years of experience, ideally blending accounting, finance, and sustainability expertise. A CPA or a Master’s degree in a relevant field is highly valued, as the role requires a level of technical precision typically found in Big 4 accounting or corporate controllership. Success in this role requires a candidate who can influence without authority. You must be able to translate complex regulatory jargon into actionable steps for stakeholders who may not be reporting experts, requiring a mix of analytical rigor and strong interpersonal communication skills.

Advice to stand out and make a successful application

Focus your application on your experience with integrated reporting and internal control systems. If you have experience navigating the shift from voluntary CDP reporting to mandatory CSRD compliance, highlight the specific methodologies you used to ensure data integrity and traceability. Given Mars' focus on its Five Principles, demonstrate how you balance 'Efficiency' with 'Responsibility' in your reporting processes. Showing that you understand the unique challenges of a global, decentralized organization will differentiate you from candidates who have only worked in centralized corporate structures.

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

The role is heavily focused on the transparency and governance aspects of sustainability. You will spend significant time ensuring that the company's claims regarding carbon reduction, social equity, and governance are backed by verifiable data that can withstand external audits. Specifically, the focus will be on the SCI (Sustainability Controls Implementation) program. This involves creating the infrastructure needed to report on environmental and social impacts with the same level of scrutiny as financial results, directly supporting the company's long-term 'Sustainable in a Generation' goals.

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

One of the steepest challenges will be data fragmentation across a global, decentralized manufacturing environment. Gathering consistent, high-quality data from diverse business segments requires navigating different IT systems and local operational nuances. Additionally, the rapidly evolving regulatory landscape poses a challenge. Keeping the reporting framework updated as new standards like ISSB or EU Taxonomy requirements change requires agility and constant vigilance to prevent compliance gaps or reporting delays.

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

A typical day might begin with a cross-functional meeting involving Public Affairs and Corporate Controllership to align on CSRD disclosure requirements. You might then spend time reviewing control documentation or tracking the progress of remediation efforts for identified reporting gaps. Afternoons often involve project management tasks, such as updating the global reporting calendar or providing guidance to segment-level sustainability teams. The variability is high, shifting between technical deep dives into accounting standards and high-level coordination meetings with global associates.

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

This role is positioned at the intersection of Finance and ESG, one of the fastest-growing areas in corporate leadership. Successful performance could lead to Director-level roles within Global Sustainability, Corporate Finance, or Internal Audit. Because you will be interacting with global stakeholders across all Mars segments, you gain high visibility that can facilitate lateral moves into operational sustainability leadership or strategic risk management roles within the company's various food and petcare divisions.

The main stakeholders you might be interacting with

You will frequently interact with the Sustainability Director and Corporate Controllership to ensure financial and non-financial reporting are harmonized. These internal partners are crucial for establishing the governance standards you will oversee. External stakeholders include auditors and regulatory bodies, while internal outreach involves Public Affairs and Segment SMES. Building strong relationships with these diverse groups is essential for ensuring data flow and maintaining the integrity of the company's sustainability disclosures.
