Stockholm, Stockholm, Sweden Edgy Systems Full time 350,000 - 550,000 per year

Edgy Systems is building the next generation of energy management software — integrating solar PV, batteries, heat pumps, and other distributed energy resources (DERs) into a unified platform for installers and building owners. Our mission is to make clean energy assets work together seamlessly, bridging operations and grid optimization.

We're looking for a
motivated engineering intern
to help us develop the first version of our platform. This is a hands-on role combining
backend development
and
DevOps/cloud engineering
— ideal for someone who loves learning, building fast, and solving real problems.

What You'll Do

  • Develop backend services in Python (FastAPI) and data pipelines for time-series and asset data.
  • Implement connectors to APIs and protocols (Victron, MQTT, Modbus, etc.).
  • Build and maintain cloud infrastructure (AWS/GCP/Azure).
  • Set up CI/CD pipelines, Docker images, and basic monitoring.
  • Contribute to authentication, API performance, and scalability.

What We're Looking For

  • A university student who can sign an internship agreement.
  • Experience or interest in Python, APIs, and cloud infrastructure.
  • Curiosity for clean energy and digital solutions.
  • A builder mindset: someone who enjoys taking ownership and learning by doing.

What We Offer

  • A hands-on role in an early-stage climate tech startup.
  • Direct mentorship from the founding team.
  • Real impact, since your work will shape the foundation of our platform.
  • Potential to join the team in a leadership role once we secure funding.

This is an
unpaid internship
, fully remote or hybrid depending on your location.
