Help Europe’s biggest buildings waste less energy.

Enersee is growing fast. We are scaling to the next phase and building the core of our energy efficiency platform to help hospitals, offices, factories, and cities become radically more energy efficient. To make that happen, we need you

We’re looking for a Full Stack Developer who thrives on shipping features end-to-end. From frontend UI to backend logic, you’ll help us deliver the technology that powers Enersee’s impact.

Why this role matters

Buildings are responsible for 40% of global energy use and a third of greenhouse gas emissions. That’s a massive opportunity—and we’re tackling it head-on.

As a Full-Stack Developer at Enersee, you’ll work across the stack to build the features that make energy audits faster, reporting simpler, and pricing smarter. You’ll make complex energy systems intuitive and scalable—helping our platform grow alongside our mission.

What you’ll do

• Build & maintain end-to-end features across frontend, backend, and data layer.
• Improve workflows like energy audits, reporting, and dynamic pricing integrations.
• Integrate and optimize connectors (Clickhouse, TimescaleDB, MQTT).
• Contribute to system architecture improvements and sprint planning.
• Bring advanced UI components (Sankey diagrams, virtual meters, etc.) to life.

Job requirements

Our ideal hire

• 4+ years of full-stack development experience.
• Strong knowledge of React and Python.
• Experience with scalable APIs and data-driven applications.
• Familiarity with tools like PostgreSQL, Clickhouse, Docker, GitHub Actions.
• Bonus: experience in energy systems, IoT platforms, or data orchestration.
• Ideally, you have solid experience in Data Science

Since we are growing fast, we are looking for the real builders who want to be in both the Antwerp and Brussels offices on a weekly basis.
