As we continue to expand our investment base, we are dedicated to building a diverse team that reflects the communities we serve.

About the role: Reporting to a Finance Manager this role requires an individual who is highly organised, capable of both dealing with multiple workstreams and running defined processes efficiently and autonomously. The team you will be working for are busy and diverse. To excel in this role, it is essential that you are proactive, keen to learn, focused, self-motivated and able to work under deadlines.  The role sits within the Octopus Energy Generation’s Funds Finance team, reporting directly into a Senior Management Accountant/Finance Manager. OEGEN Funds Finance are responsible for the financial reporting and analysis for an expanding portfolio of renewable assets that are owned by a number of Retail, Institutional and Listed Funds. These assets have a growing international presence across the UK, US, Europe, Australia and Asia. The team interacts with several other teams across OEGEN and its wider business, so it is imperative that the Management Accountant is able to build strong working relationships with both internal and external stakeholders. The Senior Management Accountant will be responsible for the delivery of the financial reporting and analysis across the portfolio. Whilst much of the day-to-day operations and accounting are outsourced, this role will be responsible for ensuring the quality of the management accounts and financial information produced at asset level and therefore will be required to spend time managing the performance of the external accounting teams. This will include supporting and improving information flows between teams, managing the quality of their outputs and establishing appropriate controls. The Senior Management Accountant will also be required to assist with new investment transactions, manage budgets and audits and delivery against them and also lead on ad hoc projects.  This role is an 18-month FTC

It could be the start of something, well, extraordinary. SOUNDS GREAT, WHAT WILL I BE DOING? 🤔 As our Junior Management Accountant you'll get hands-on with the day-to-day management accounting for several of our global entities — working closely with our Senior Management Accountants to keep our books accurate, our accounts reconciled, and our month-end running like clockwork.

You’ll need to be flexible, comfortable with continuous change, and working in a high-tempo environment. WHAT DO I NEED TO BRING WITH ME? 🧳 You’ll need to be able to demonstrate the core skills this role requires.

We want people who think big (to make an impact), ask why (to find a better way), and show respect (to everyone, at every level, all the time). Those are our values, and they’re a big part of what we’re looking for in you. WHY JOIN US 👉 Own real work from day one. You'll run your own entities and reconciliations — not just watch someone else do it. 👉 Learn from people who've done it. Our Senior Management Accountants will help you grow, from talking through tricky reconciliations to supporting your ACCA/CIMA/ICAEW study. 👉 Get exposure most junior roles won't give you. Global entities, multiple currencies, audit, tax, payroll — you'll build skills that set you apart, fast.   WHAT WE OFFER 🧘 At GWI, you’ll find meaningful work, visible impact, and a culture that empowers you to do your best.
