Anthesis is seeking a Sustainability Data Expert to join our Circularity and Value Chain Transformation team. (Note: We are welcoming applicants based in the UK and EMEA for this role.)

This role is critical in helping clients transform complex sustainability, packaging, product, waste, and regulatory data into meaningful insights that support compliance, business decision-making, and sustainability outcomes.

As a senior technical specialist, you will combine sustainability expertise with advanced analytical capabilities to manage, analyse, and interpret large and complex datasets.

You will develop robust methodologies, perform complex calculations, oversee data quality and assurance processes, and support clients in understanding the story behind their data.
A significant proportion of the role will focus on regulatory compliance requirements, including Extended Producer Responsibility (EPR), the Packaging and Packaging Waste Regulation (PPWR), and other sustainability reporting obligations.

Working closely with clients and project teams, you will ensure analytical outputs are accurate, auditable, and defensible while communicating complex findings in a clear, concise, and actionable manner. You will also play a key role in mentoring team members, setting technical standards, and building capability across the wider team.
