Octopus Energy Generation ☀️
Fixed Term Contract
London (UK)
Job Description
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 £8bn in renewable energy assets worldwide.
We are looking for an experienced Finance Systems Administrator with strong, practical knowledge of both Yooz, or a comparable purchase-to-pay system, and SAP.
You will join a dynamic transformation function supporting a global portfolio of renewable energy assets. You will work closely with Finance, Fund Operations and Asset Management teams, as well as external asset managers and third-party system providers, to maintain reliable systems and effective financial controls.
You will take day-to-day ownership of Yooz administration and support the associated purchase-to-pay processes across a complex portfolio of energy assets. This is a hands-on role requiring someone who can quickly understand existing configurations, investigate issues independently and maintain strong financial controls.
You will work with supplier master data, bank-detail changes, invoice and payment workflows, user access and approval structures. You will need to exercise sound judgement, understand requests accurately and recognise when an issue can be resolved independently and when it should be stopped or escalated.
Whilst we maintain a degree of flexibility, this position requires an average of three days per week in the office. This is an initial 12-month fixed-term contract.
What you'll do
Yooz administration and purchase-to-pay support- Act as the primary day-to-day administrator for Yooz, managing system configuration, operational queries and issue resolution.
- Manage supplier onboarding and amendments, including bank-detail changes, in line with established verification and approval processes.
- Maintain invoice, purchase order, payment and approval workflows, including user roles, permissions, approval limits and access rights.
- Investigate and resolve invoice-routing, data and processing issues across Yooz, SAP and connected systems. This can include collaboration with internal and external stakeholders.
- Perform reconciliations between systems and support safe correction or reprocessing where transactions have failed or been recorded incorrectly, while managing duplicate-posting and payment risks.
- Apply appropriate controls to supplier data, payments and user access, maintaining segregation of duties and clear audit trails.
- Ensure manual overrides and administrator functions are used only where appropriate and fully documented.
- Support system enhancements, integrations, testing and migration activity across Yooz, SAP and related finance platforms.
- Maintain system documentation, access records and process guidance, while identifying opportunities to simplify workflows and reduce manual intervention.
What you'll need
Essential- Demonstrable hands-on experience administering Yooz, or a comparable purchase-to-pay system in a live finance environment.
- Practical experience using and supporting SAP, ideally within accounts payable, supplier management or purchase-to-pay processes.
- Experience managing supplier records, bank-detail changes, invoice workflows, approval chains and user access.
- Strong understanding of purchase-to-pay controls, segregation of duties and the risks associated with supplier and payment data
- The ability to investigate and resolve finance-system issues, interpret available evidence and progress appropriate solutions independently.
- Strong attention to detail and the ability to manage competing operational priorities without weakening controls
- Clear written and verbal communication skills, including the ability to understand requests accurately and explain system issues in plain English.
- Experience supporting system change, enhancement, testing or migration activity.
- Experience integrating or reconciling data between Yooz and SAP.
- Experience in renewable energy, infrastructure, investment management or another asset-backed environment
- Familiarity with SAP finance modules and accounts-payable processes.
- Experience working with external asset managers, outsourced finance providers or third-party system vendors.
- Experience documenting finance-system processes, controls and operating procedures.
