Their culture is built on a foundation of radical candour and mutual trust.

Individually, the team operates with high autonomy; collectively, they’re unified by a shared drive to achieve their mission through a commitment to excellence.

The Role

They’re looking for a frontend engineer with experience building complex, performant, dynamic web applications for visualising and navigating data.

You’ll be responsible for building core frontend components and interfaces, as well as extending them to drive customer-specific workflows across a variety of sectors.

This is a high-impact role suited to someone who can rapidly bring a prototype from concept to execution while choosing robust, reusable abstractions.
