Senior Software Engineer

You'll join as the senior technical contributor and become one of the key architects of the platform, helping define the systems, standards, and technical direction that future engineers will build upon.

You'll have genuine ownership, significant influence, and the opportunity to solve complex engineering challenges where software meets the physical world.

What You'll Build

• Energy optimisation systems for operating battery and energy assets.
• Data platforms and pipelines supporting large-scale energy infrastructure.
• Asset management systems covering monitoring, invoicing, and operational workflows.
• Observability tooling, including logging, alerting, and dashboards.
• Backend services supporting commercial, operational, and engineering teams., * Become one of the founding engineers in a rapidly growing business.
• Shape the architecture and engineering culture from day one.
• Work on technology directly enabling Europe's energy transition.
• Solve real-world challenges where software interacts with physical infrastructure.
• Join a collaborative, ownership-driven culture with genuine autonomy.
• Work alongside founders with a proven track record of delivering large-scale energy projects.

The Opportunity

For the right engineer, this is a chance to build something that matters.

• Strong backend software engineering experience using Python, JavaScript, TypeScript, or similar technologies.
• Experience building scalable, production-grade systems.
• Strong understanding of software architecture, distributed systems, and modern backend development.
• Experience designing and maintaining data pipelines and data-driven applications.
• Experience working on complex systems, ideally within energy, infrastructure, Industrial IoT, hardware-connected products, or other mission-critical environments.
• Strong stakeholder communication skills with the ability to work across technical and non-technical teams.
• Comfortable taking ownership in a fast-moving environment with minimal bureaucracy.

Europe's energy infrastructure is being rebuilt in real time. Battery depots. Truck charging networks. Decentralised industrial energy systems. The physical infrastructure is scaling rapidly. The software behind it is still being built. Our client is a well-funded energy technology business founded by the team behind one of Scandinavia's largest Battery Energy Storage System projects. Their mission is ambitious: deploy 1 terawatt-hour of clean energy capacity across Germany and Sweden by 2030.
