Our mission is to provide innovative services that are critical to society, unlocking a cleaner, better and more profitable future. Working towards this goal, Volue has become a leading technology supplier and enabler of the green transition, helping energy companies simplify and optimise their daily operations.

We are now looking for a Software Engineer who wants to help shape solutions that enable customers to make informed decisions in volatile short-term markets. You will design, implement and maintain data pipelines, take ownership of model input data management, and create insightful analyses and visualisations for day-ahead, intraday and balancing markets.

In our day-to-day work, we value collaboration and continuous learning: pair programming, joint learning sessions, and recurring innovation days to explore new ideas are part of how we grow together. We work in an agile, digital environment with fast feedback loops and a strong culture of learning, knowledge sharing and personal development.

What you will be doing to make a difference

• Design, build and maintain flexible, scalable end-to-end data pipelines together with other software and data engineers.
• Ensure high data quality and reliability, implementing appropriate tooling in collaboration with data scientists.
• Work closely with in-house analysts to understand the energy domain and the data behind it.
• Translate complex data into meaningful visualisations - both for internal analysis and, together with Product and UX, for customer-facing dashboards.

What do you need to succeed in the role?
