Senior Backend Software Engineer

Heimdall Power is a fast-growing Norwegian tech company established in 2016. We have global ambitions and are already present in several European countries as well as the US and Asia. We provide solutions to optimize power grids worldwide, promoting a swift, secure, and affordable transition to green energy. Our unique offering combines software and sensors to increase grid capacity and monitor asset health. By enabling the more efficient use of existing infrastructure, we reduce carbon footprints while creating value for society, industry, and our shareholders.

We are looking for a Senior Backend Software Engineer to help shape and deliver the core software powering Heimdall Power's grid operations platform. You will play a key role in designing and developing scalable backend services that enable real-time data processing, grid insights, and operational insights for utilities worldwide.

This is a hands-on senior engineering role focused on building backend services and software components that integrate with utility operational systems. You'll contribute to data pipelines, APIs, and automation that help our customers operate the power grid more efficiently and safely. This includes implementing aggregation techniques for time-series data, developing features that improve both user-facing insights and developer observability, and building robust backend infrastructure that supports both cloud and customer-hosted deployments.

You'll join a team that values clarity, simplicity, and long-term maintainability. We work from a monorepo, use shared infrastructure and tooling, and apply Domain-Driven Design (DDD) to ensure our software accurately reflects the complexity of the energy grid. We aim to build things once—and build them right.
