Interim Treasury Manager in London

Field is an international builder, owner, operator, of renewable infrastructure. Our Founder and CEO is a successful entrepreneur who previously co-founded a green energy supplier. We have robust pipelines of BESS projects across the UK, Italy, Spain, and Germany - and strong financial backing. Our most recent fundraise was a £200 million investment from DIF Capital Partners. This will support our mission to grow internationally, and ultimately to build and develop a robust global BESS portfolio.

This is a hands‐on role covering the day‐to‐day operational treasury workload including counterparty credit monitoring, insurance and surety bond administration, cash management, and supporting the Debt & Structured Finance Manager on facility compliance and reporting. The interim will be expected to integrate quickly, uphold existing processes and controls, and provide reliable coverage across a broad range of treasury responsibilities for an estimated engagement of 6 months with a potential for this to be extended.

  • Manage the transition of assets from construction-phase to operational insurance programmes, working closely with project delivery teams to ensure seamless coverage handover at practical completion.
  • Ensure insurance requirements under project finance facility agreements are met and documented, and that lender‐side insurance conditions are tracked and satisfied throughout the life of each project.
