Senior Software Developer - Back Office

Do you enjoy turning complex business needs into simple, reliable software solutions? And are you motivated by working closely with the people who use the systems you build?

In Back Office, Client Solutions, you will develop solutions side by side with users, ensuring high data quality and efficient workflows that support critical business processes across the organisation.

About the team

Back Office, Client Solutions is part of Finance and works behind the scenes to ensure that contracts, data and settlements are aligned – correctly and on time. The team’s responsibilities span operations, controlling, development, and project work, covering areas such as settlement of energy products, reconciliation of invoices, and handling of market-related data.

The team is a close-knit mix of business specialists and developers — not split into separate business and IT departments. You will work side by side with the people who use the systems you build, giving you direct insight into the processes your software supports and an immediate sense of the impact your work has.

The team collaborates widely across the organisation as well as with external partners. A strong focus on optimisation, data quality, and teamwork drives the way the team operates.

Key responsibilities

In this role, you will work across development, optimisation, and operational support, contributing to both new solutions and improvements of existing systems.

• Design, develop and test new software solutions
• Optimise and enhance existing software to support evolving business needs
• Support daily operations within Back Office, Client Solutions
• Improve and automate workflows and processes through software solutions
• Manage and maintain code documentation

You are curious by nature and motivated by understanding the business behind the code. As a senior developer, you take ownership, challenge existing ways of working, and enjoy driving improvements that create real value. If you thrive on close collaboration, want to influence technical solutions, and like seeing the direct impact of your work, I think you'll enjoy being part of this team.
