Senior Manager, Finance - Sustainability

Mars • United States • Added on Oct 29, 2026
Apply →

This senior finance partner will connect Mars’ sustainability ambitions with planning and investment choices across its global snacking business. The role centers on understanding costs, testing business cases and showing leaders what sustainability initiatives may mean for budgets, returns and long-term value. It also brings financial performance and sustainability measures into clearer view for decision-makers.

The work covers initiatives such as decarbonization, renewable energy, packaging optimization, waste reduction, water efficiency and sustainable sourcing. Its contribution is to make trade-offs visible: where investment can support environmental commitments, manage operating costs and create measurable business value. Better financial information can also help teams track progress and take responsibility for spending and outcomes.

This suits someone who combines strong FP&A and investment analysis with an interest in environmental goals, and who can explain complex data clearly to finance and non-finance colleagues. Experience in consumer goods or manufacturing would help when assessing how sustainability choices connect with operations and business performance.

Job FAQs

What are the main missions and responsibilities of this role?

The role links sustainability priorities with financial planning across Mars' Global Snacking business. It could involve building budgets and forecasts, modeling investment cases, assessing risks and returns, and tracking the financial benefits of initiatives such as energy efficiency, packaging changes and waste reduction. A longer-term aim is to make sustainability spending and outcomes more transparent, helping leaders compare options and connect environmental commitments with business performance. The role also supports consistent financial data and reporting for sustainability-related decisions.

Key learning opportunities for this job

The position could deepen expertise in sustainability finance, including how decarbonization, renewable energy, packaging and sourcing initiatives affect capital needs, operating costs and returns. Working across Finance, Sustainability and Procurement may build understanding of how environmental priorities translate into business plans. The role also offers scope to develop financial storytelling, scenario analysis and sustainability data practices. The posting mentions digital tools such as SAP and Power BI, though it does not specify formal training, certifications or a mentoring program.

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

A strong candidate would bring at least 5-8 years of experience in finance, FP&A, business partnering or sustainability finance, with a degree in a relevant field. Financial planning, forecasting, modeling, business-case evaluation and investment analysis are central skills; consumer goods or manufacturing experience is preferred. The role also calls for the ability to connect non-financial sustainability data with measurable financial outcomes. Clear communication, sound judgment and the confidence to influence colleagues across functions would matter. An MBA or relevant professional certification is preferred, not stated as mandatory.

Advice to stand out and make a successful application

Use a concise example to show how you evaluated an investment, including assumptions, costs, expected benefits, payback or ROI, and how the decision changed after your analysis. If the example involved environmental goals, explain both the financial trade-offs and the impact measure used. For Mars, tailor your application to consumer goods or manufacturing economics where possible. Show how you have worked with non-finance teams, turned complex data into a clear recommendation, and monitored results after approval. Mention relevant experience with FP&A systems or analytics tools such as SAP or Power BI if applicable.

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

The role is likely to focus on the financial dimensions of environmental initiatives named in the posting: decarbonization, renewable energy, packaging optimization, waste reduction, water efficiency and sustainable sourcing. It connects these areas with planning, investment prioritization and measurement of business benefits. It may also support sustainability-related financial data quality and internal reporting. The position is a finance partner to sustainability work rather than a technical environmental operations role, and the posting does not identify specific targets or reporting frameworks.

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

A likely challenge is comparing initiatives with different costs, timelines and forms of benefit, especially when environmental outcomes and financial returns do not align neatly. Forecasts may also depend on operational data collected across regions and functions. The role will need to question assumptions while maintaining productive partnerships with Sustainability, Procurement and Finance colleagues. Establishing consistent measures and reliable data for both spending and outcomes could take sustained coordination.

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

A day could include reviewing sustainability forecasts or actual spending, checking assumptions behind an investment case, and discussing risks or performance gaps with Finance and Sustainability colleagues. The person may also work with Procurement or other teams on the costs and expected benefits of an initiative. Other time could go to scenario analysis, reporting dashboards or preparing a concise recommendation for leaders. The balance would likely shift with planning cycles, investment decisions and requests for updates on sustainability commitments.

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

The role could build a specialist profile in sustainability finance while broadening experience in strategic FP&A, investment decisions and cross-functional business partnering. Exposure to global snacking and sustainability leadership may also provide opportunities to work on initiatives across regions and business functions. Potential future directions could include broader finance leadership, sustainability finance, or planning roles with wider business scope. The posting does not specify a promotion path, so growth would depend on performance and organizational needs.

The main stakeholders you might be interacting with

The closest partners are likely to be Sustainability and Finance leaders, including colleagues in Global Snacking FP&A and business partnering. The role also works with Procurement and other functions involved in sustainability initiatives and their financial planning. Regional and corporate teams may contribute plans, assumptions and performance data. Reporting teams could be involved in improving the accuracy and consistency of sustainability-related financial information, while senior leaders use the resulting analysis to make investment decisions.
