Senior User Experience (UX) Designer

About us

HELIX is the first company to spin out of Google X. Backed by Silicon Valley venture capital firms and prestigious global real estate firms, we work with large-scale real estate tenants and building owner/operators in the US, Europe and Asia. Our clients need accurate and usable 3D building models generated quickly for construction and occupancy planning, asset purchase analysis and more. We use advanced data capture (LiDAR and photogrammetry), spatial machine learning and cloud compute technology to relentlessly reduce the time and cost to generate easy to consume digital building models.


As a HELIX Senior User Experience (UX) Designer you will lead our efforts to create a stunning, modern and intuitive web application that defines how our users engage with building data.
