Systems Administrator

At Octopus Energy Generation (OEGEN), we're passionate about powering a sustainable future. As pioneers in the renewable energy space, we don’t just invest in utility‑scale projects; we invest in people, communities, and a greener tomorrow.

Since stepping into the renewables arena in 2010, we've made waves - becoming a top investor in onshore wind across mainland Europe and the largest backer of solar power in Europe. Today, we proudly manage over £7bn in renewable energy assets worldwide.

In this role you will maintain day to day operation and control of OEGEN’s financial payments systems (SAP, Yooz, Horizon), including user access, master data, workflows and month end system activities. The role supports portfolio growth and system change, ensuring business as usual remains stable while the finance systems landscape evolves and simplifies over time.

Whilst we maintain a degree of flexibility, this position requires an average of 3 days in the office per week.

• Look after system set‑up, master data, supplier onboarding, bank details and user access
• Own purchase order and invoice approval workflows and keep them working nicely
• Make sure system docs, access records and audit evidence are always in good shape
• Keep finance systems configured so accounting and reporting just work

• Support system changes and migrations, including data checks and parallel runs
• Help design, test and roll out better workflows, access models and controls
• Spot ways to simplify processes, cut manual work and improve reliability
• Help keep us safe by supporting system controls, supplier controls and audits
• Flag risks or control gaps early and help put sensible fixes in place

• Hands on experience administering finance or other business critical systems.
• Strong understanding of core finance processes and controls (e.g. general ledger, AP/AR, approvals, reconciliations).
• Experience supporting system change, enhancement or migration activity.
• Comfortable working directly with Finance and Asset Management teams.
• Strong attention to detail with a control-focused mindset.
• Clear, pragmatic communicator able to explain system topics in plain English.

• Experience with enterprise finance systems (e.g. SAP).
• Exposure to invoice workflow tools (e.g. Yooz) and financial reporting platforms (e.g. Horizon).
• Experience working in asset‑backed, infrastructure or investment management environments.
• Familiarity with segregation of duties frameworks, audit processes or regulated environments.
• Experience working with third party system vendors and external support teams.

• 💰 Wondering what the salary for this role is? Just ask us! On a call with one of our recruiters it's something we always cover as we genuinely want to match your experience with the correct salary. The reason why we don't advertise is because we honestly have a degree of flexibility and would never want salary to be a reason why someone doesn't apply to Octopus - what's more important to us is finding the right octofit!
