About viboo

Our mission at viboo is to reduce the environmental impact of buildings while helping property owners lower operational costs. We therefore developed an AI-based Building Management System (BMS) built on top of scalable IoT infrastructure. The system uses self-learning AI to predictively optimize heating energy consumption in buildings, one of the largest contributors to global carbon emissions.
We are looking for a Senior Software Engineer to join our impact-driven ETH spin-off, starting immediately or by agreement. In this role, your expertise in software engineering, cloud architecture, and databases will play a key role in powering and scaling our AI-based BMS.

• Contributing to overall product development and expanding your competencies and knowledge.
• Debugging issues and optimizing platform performance during on-call shifts.
• Conducting peer reviews of code written by AI and other developers.
• Reporting directly to the CTO on an ongoing basis.

You’re a perfect fit if you have ...

• Proven experience with public cloud providers; GCP experience is a strong advantage.
• Deep expertise in PostgreSQL and TimescaleDB, with solid experience managing and processing time-series data.
• Strong knowledge of CI/CD pipelines and DevOps practices with Kubernetes; familiarity with MLOps tooling, particularly Kubeflow and Prometheus, is a plus.
• Hands-on experience building software with AI agents, AI assistants, and Model Context Protocol (MCP).
• A proactive, driven mindset with intellectual curiosity, a user-centric approach, and a genuine commitment to team collaboration.
