Data Visualisation Designer

Salary: £45,000 - 65,000 per year

Requirements:

• Strong portfolio showing advanced data visualisation, geospatial interfaces, map-based products or complex analytical software.
• Proven UX/UI design experience in custom software products, ideally B2B, SaaS, defence, maritime, intelligence, logistics, GIS or another complex domain.
• Excellent visual design craft, with strong judgement around layout, hierarchy, typography, colour, interaction states and information density.
• Good understanding of cartographic design principles, including layers, projections, scale, symbology, spatial relationships and map readability.
• Experience designing for large or complex datasets, including aggregation, filtering, clustering, zoom-level behaviour and progressive disclosure.
• Familiarity with geospatial and visualisation tools or libraries such as Kepler.gl, deck.gl, Mapbox GL JS, CesiumJS, D3, Three.js, QGIS or ArcGIS.
• Ability to design 3D geospatial experiences such as globes, terrain, extruded data, sensor volumes, movement paths or layered operational scenes.
• Comfortable working with technical teams and discussing APIs, data schemas, rendering constraints, front-end implementation and performance trade-offs.
• Strong grasp of data storytelling and visual analytics: helping users move from raw data to interpretation, insight and action.
• Interest in maritime domain awareness, vessel behaviour, earth observation, remote sensing, intelligence analysis or national security use cases.

Responsibilities:

• Design high-quality 2D and 3D geospatial visualisations for maritime surveillance, intelligence analysis and operational decision-making.
• Turn complex maritime datasets into clear visual patterns, trends, anomalies, behaviours and insight-led user journeys.
• Create wireframes, prototypes, interaction models and polished UI designs for map-led product experiences.
• Design visual treatments for vessel tracks, movement histories, density maps, heatmaps, clusters, routes, zones, alerts, sensor coverage and analytical overlays.
• Work with product managers, engineers, data scientists and maritime domain experts to understand customer workflows and mission needs.
• Define visual systems for geospatial data, including colour, symbology, hierarchy, confidence, uncertainty, severity and temporal change.
• Prototype advanced visualisation concepts using tools such as Figma, Kepler.gl, deck.gl, Mapbox, Cesium, D3, QGIS or similar.
• Partner with front-end engineers to ensure designs can be implemented effectively in custom web software at large data scale.
• Test and refine designs with internal experts and customer users, balancing visual impact, analytical clarity and operational usability.
