Job description

Do you want to rethink how building projects are planned – not from the sidelines, but right at the heart of it?

At vyzn, we’re shaping the future of construction planning with a data- and AI-driven SaaS platform. In just a few clicks, developers, planners, and architects receive precise insights on emissions, energy, comfort, and costs - based on automatically refined 3D building models - along with AI-powered recommendations to support well-informed decisions.

As a Lead Developer (80–100%), you’ll be part of a team that doesn’t just think big, but also makes things happen. If you’re motivated to help shape an ambitious ETH spin-off that combines sustainability and AI, then you’re exactly who we’re looking for.
