A leading global private markets investment firm is seeking a sustainability and decarbonization professional to join its growing function. This role is positioned at the heart of the platform, operating across portfolio value creation and firm-wide decarbonization strategy. Unlike traditional sustainability roles, this position is highly operational and people-facing, centred on driving delivery across multiple workstreams, managing complex information flows, and acting as a trusted conduit between investors, portfolio companies, investment teams, and senior leadership. This will suit someone who thrives in a fast-moving environment, enjoys solving problems through coordination and communication, and can turn technical decarbonization work into clear, compelling outputs for internal and external stakeholders.

Investor Engagement & Fundraising Support

Serve as the primary liaison between the decarbonization team and the firm’s Investor Relations function.
Lead all decarbonization-related investor communication across multiple funds.
Build high-quality materials for DDQs, RFPs, ongoing reporting cycles and ad-hoc investor requests.
Support fundraising processes with sustainability-aligned materials and performance narratives.
Coordinate information across teams, ensuring consistency of messaging and timely delivery.
Synthesise complex portfolio progress into clear, investor-ready outputs.

Portfolio Value Creation (Core Focus)

Support execution of decarbonization initiatives across portfolio companies, working closely with management teams.
Translate company-level progress into structured annual and quarterly performance plans.
Help drive delivery of value-creation projects, ensuring milestones are met and stakeholders remain aligned.
Work with deal teams to embed decarbonization thinking into underwriting, onboarding, and ongoing portfolio strategy.
Operate as a problem-solver who can move between strategic discussions and hands-on coordination.

Who Would Suit The Role

Someone highly organised who can manage relentless volume, switching quickly between IR, portfolio support and internal requests.
A polished communicator who can turn technical data into clear, compelling narratives without relying on jargon.
A relationship-builder who is credible with management teams, investors, and investment professionals.
Someone who enjoys operational delivery rather than theoretical ESG strategy.
An individual comfortable with ambiguity, changing priorities, and a “people-first” working style.
Someone motivated by the mission but grounded in practical execution.

Candidate Profile

6–9 years of experience across sustainability operations, decarbonization, investor relations, portfolio value creation, consulting, or private markets.
Strong exposure to carbon accounting frameworks or sustainability metrics (but not necessarily as a technical specialist).
Prior experience dealing with investors, DDQs, or cross-functional corporate stakeholders.
Outstanding writing ability and exceptional verbal communication.
Strong project/process management skills.
Motivated by industrial decarbonization and the energy transition, with the ability to engage senior stakeholders confidently.
Bachelor’s degree required; Master’s preferred.
