About the Role
Build the next generation of mission-critical visual technology. We're partnering with one of the UK's most exciting defence technology start-ups—a rapidly scaling business bringing together exceptional engineers from Palantir, Microsoft, Tractable and other world-leading technology companies.
Their mission is to build cutting-edge software that gives users unparalleled awareness of complex, real-world environments. Think digital twins, real-time situational awareness, AI-powered analytics, geospatial intelligence, sensor fusion and immersive 3D visualisation.
They're now looking for a Senior Frontend Engineer to help shape the visual experiences behind these next-generation platforms.
This is a chance to work on products that push the boundaries of modern frontend engineering, blending beautiful user experiences with complex data, real-time systems and advanced graphics.
What you'll be building
- High-performance 3D digital twin applications that mirror real-world environments.
- Interactive geospatial mapping platforms combining live operational and sensor data.
- Rich data visualisation tools that transform millions of data points into intuitive, actionable insights.
- Immersive mission planning and situational awareness interfaces.
- Real-time dashboards powered by streaming data and AI-driven analytics.
- Next-generation visual platforms that fuse software, hardware and autonomous systems into a seamless user experience.
