• 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.

What you’ll be doing

• Building modern frontend applications using TypeScript, React and modern web technologies.
• Developing high-performance 3D graphics using technologies such as Three.js, WebGL, Babylon.js or similar.
• Creating advanced mapping experiences using platforms such as Mapbox, Cesium, Leaflet or comparable GIS technologies.
• Building sophisticated data visualisations using libraries such as D3.js, Deck.gl or similar.
• Optimising rendering performance for large-scale datasets and real-time visualisation.
• Working alongside software, systems, AI and hardware engineers to build truly integrated products.
• Helping shape the technical direction of an engineering-first organisation.

What they’re looking for

You’ll likely have experience with several of the following:

• Commercial frontend development using React, TypeScript or JavaScript.
• 3D graphics, rendering or visualisation technologies.
• Digital twins, simulation platforms or interactive visual environments.
• Geospatial technologies, GIS or mapping platforms.
• Real-time data processing and streaming applications.
• Data visualisation and analytical interfaces.
• Performance optimisation for graphics-heavy web applications.
• A passion for solving technically challenging problems and building products that genuinely make an impact.

Why join?

• Work alongside an exceptional engineering team from Palantir, Microsoft, Tractable and other elite technology companies.
• Build products at the intersection of AI, digital twins, autonomy, geospatial intelligence, sensor fusion and advanced visualisation.
• Solve complex engineering challenges using cutting-edge technology with real-world impact.
• Join a fast-growing, well-funded start-up where you’ll have genuine influence over both the product and engineering direction.
• Competitive salary, equity and an excellent benefits package.
• Hybrid working with a collaborative, engineering-first culture that values innovation, autonomy and technical excellence.
