• Lead fund ESG reporting: Take ownership of ESG data and disclosures for selected funds, supporting regulatory, investor and internal reporting needs.
• Stewardship and engagement: Work with investee companies and third-party asset managers to support ESG improvements in both strategy and operations.
• Contribute to ESG integration in investments: Support ESG due diligence on new investments, assessing risks, negotiating ESG data provisions into contracts, and identifying early-stage opportunities for delivering environmental or social value.
• Drive ESG reviews: Conduct regular ESG assessments and reviews with asset managers and service providers, identifying risks, gaps, and areas for improvement.
• Measure and manage carbon: Support Scope 1, 2 and 3 emissions measurement, including data gathering and the application of carbon accounting methodologies.
• Track regulation: Keep current with ESG regulation, ensuring our processes meet evolving expectations.
• Support impact initiatives: Collaborate with asset teams and stakeholders on biodiversity, community and circular economy projects.
• Tell compelling stories: Translate raw ESG data into case studies and insights that engage investors and demonstrate the value of our ESG work.

What you will need:

• 1–5 years’ experience in ESG, sustainability or sustainable finance, ideally with exposure to infrastructure, real assets or investment funds.
• Familiarity with sustainability regulations and standards (e.g. SFDR, EU Taxonomy, TCFD, CSRD, PRI).
• Practical experience in carbon footprinting and ESG data collection preferred.
• Strong quantitative and analytical skills with the ability to work across complex data sets.
• Comfortable building or managing reporting platforms and tools; experience streamlining data processes and identifying improvements.
