This dual-impact role balances strategic sustainability leadership with high-level operational support. You will take full ownership of the company’s ESG agenda, from managing B Corp re-certification to calculating detailed carbon footprints. Simultaneously, you will act as a right-hand to the COO, driving critical retail expansion projects and translating complex data into actionable business cases for the executive board.

Working for a certified B Corp means sustainability is not a side project; it is the core of the business model. You will have the unique opportunity to integrate circularity and ethical sourcing directly into the supply chain of a fast-growing pet health brand. This role bridges the gap between environmental stewardship and commercial scalability, ensuring that as the company grows, its positive impact intensifies.

This suits someone who possesses a highly analytical mindset and the professional maturity to navigate both supply chain technicalities and boardroom discussions. You should be a versatile project manager comfortable switching between carbon accounting and retail strategy.

Job FAQs

What are the main missions and responsibilities of this role?

The role is split equally between sustainability and strategic operations. You will manage the B Impact Assessment process, ensuring the company maintains its high standards, while also overseeing carbon accounting across Scopes 1, 2, and 3. On the operations side, you will drive retail expansion and channel-specific projects to support the COO. You will also be responsible for regulatory compliance, specifically keeping pace with EU packaging regulations and VSME/CSRD requirements. Beyond reporting, you will be expected to translate sustainability goals into concrete actions within the supply chain and packaging sectors, while preparing management presentations for board meetings.

Key learning opportunities for this job

Candidates will gain deep expertise in the B Corp ecosystem, moving beyond simple compliance to implementing new B Lab standards. This is a rare chance to see how a certified company evolves its impact over time. Additionally, the direct reporting line to the COO offers a masterclass in operational scaling and retail strategy. You will learn how to build business cases that align environmental KPIs with commercial growth, gaining high-level exposure to how a fast-moving consumer goods (FMCG) startup navigates investor and partner expectations.

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

The ideal candidate brings several years of experience in ESG management, specifically within the FMCG or food sectors. Proficiency with carbon footprinting tools and a solid understanding of the B Corp framework are essential technical requirements. We look for a professional who is analytically rigorous but remains hands-on. You must be comfortable communicating in both German and English and possess the confidence to interact with external retail partners and internal executive leadership alike.

Advice to stand out and make a successful application

To stand out, demonstrate a clear understanding of the B Corp movement and how it applies to the pet food industry. Mention specific experience you have with life cycle assessments or sustainable packaging, as these are critical to their supply chain. Since this role supports the COO, highlight your project management methodology. Providing examples of how you have used data to influence management decisions or how you managed cross-functional projects between finance and supply chain will be highly beneficial.

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

The role focuses heavily on responsible supply chain management and circularity. With a significant portion of the impact living in Scope 3, you will work closely with suppliers to reduce carbon intensity and improve packaging sustainability. Internal culture is another pillar; you will act as a sustainability ambassador, ensuring that the mission-driven values of a B Corp are understood and lived by all team members through training and transparent internal communication.

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

A primary challenge will be the dual nature of the role, requiring you to balance the long-term, data-heavy requirements of ESG reporting with the fast-paced, urgent demands of the COO Office and retail projects. Navigating shifting regulations like the CSRD and new packaging laws while the company is in a high-growth phase requires agility. You will need to ensure that sustainability does not become a bottleneck for retail expansion but rather a competitive advantage.

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

Your morning might start with analyzing Scope 3 emissions data or updating the B Impact Assessment dashboard. By midday, you could be meeting with the retail team to discuss the sustainability requirements of a new major trade partner. In the afternoon, you might switch gears to prepare a KPI report for a board meeting or collaborate with the SCM team on sustainable sourcing strategies. The day often ends with strategic planning sessions alongside the COO to track progress on high-priority business milestones.

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

Given the proximity to the COO and the broad scope of the role, there is a clear path toward senior strategic leadership. You could eventually specialize further into a Head of Sustainability role or move into a broader Operations Director position. As the company expands internationally, you may also lead global impact initiatives, overseeing the sustainability strategy across new markets and diverse regulatory environments.

The main stakeholders you might be interacting with

You will be a key link between the COO and the wider management board, including investors and retail partners. Your internal network will be broad, encompassing Finance, Marketing, and Supply Chain Management. Externally, you will represent the company to B Lab, sustainability auditors, and major retail buyers who increasingly demand transparent ESG data before listing products.
