Octopus Energy has grown exponentially in its short history. It is now a complex multi-billion turnover international group, which participates in multiple industry verticals including retail utilities, utilities management, generation, EV leasing and software sales.

We are committed to innovation, sustainability, and customer satisfaction. As part of our growth strategy, we are implementing NetSuite and a number of supplementary Finance applications e.g. OCR, AP Management to streamline our finance operations and improve efficiency. We are seeking a Finance Systems Business Analyst to play a key role in these initiatives.

Its legacy business management applications are at the limit of their capacity and capability. A new enterprise resource planning tool (ERP) is required to both provide a finance back bone for the Group, and to integrate information flows and insights across the group. Oracle’s NetSuite SAAS platform has been selected for this task. The process to select supplementary applications is underway.

This role will be pivotal in ensuring the ongoing success of Finance and its systems for the Group and is key to maintaining appropriate controls that reflect the Group’s segregation of duties. It will also be pivotal in defining streamlined processes & procedures across the Group.

Working in Octopus’ Finance Systems & Transformation team, you will be responsible for leading & performing end to end testing of Financial applications and transformation projects. You will also be responsible for building developing test management best practice, writing test strategies and supporting business stakeholders with testing.

Finance sits at the heart of any organisation and thus close coordination and integration with other teams and tools within Octopus is frequent. You will be required to test new systems managed both inhouse and by 3rd parties.

If this sounds like you then we'd love to hear from you.

Are you ready for a career with us? We want to ensure you have all the tools and environment you need to unleash your potential. Need any specific accommodations? Whether you require specific accommodations or have a unique preference, let us know, and we'll do what we can to customise your interview process for comfort and maximum magic!

Studies have shown that some groups of people, like women, are less likely to apply to a role unless they meet 100% of the job requirements. Whoever you are, if you like one of our jobs, we encourage you to apply as you might just be the candidate we hire. Across Octopus, we're looking for genuinely decent people who are honest and empathetic. Our people are our strongest asset and the unique skills and perspectives people bring to the team are the driving force of our success. As an equal opportunity employer, we do not discriminate on the basis of any protected attribute. Our commitment is to provide equal opportunities, an inclusive work environment, and fairness for everyone.
