Website LDN\_data Greater London Authority (GLA)
We are looking for a technically experienced, visually literate, data viz developer to work on predominantly web-based interactive data projects, and join our team of developers, designers, data scientists, analysts and engineers in the Greater London Authority’s City Intelligence Unit.
You will have the opportunity to produce high profile outputs, used by the Mayor and senior staff as well as working on more technical outputs for specialist users in the London Boroughs and across London’s public, private and voluntary sectors.
You will have a few years’ experience building engaging data visualisation projects, be able to use and adapt common visualisation libraries, and be able to create custom visualisations from scratch using Svelte & D3. Ideally you will have worked querying and bringing large datasets to the web in the past, and have an interest in connecting spatial and non-spatial data.
We are particularly interested in data viz developers who are visually literate and have a good sense of what works well in communicating data to a diverse audience (public & professional).
You will have a predominantly technical background, with experience of (some, but not all) technologies like Svelte, D3, ObservablePlot, TypeScript, MapLibre, DeckGL, SVG, Canvas HTML, CSS, Tailwind & Git. Experience of VegaLite, Vue, React, Leaflet &MapBox also useful.
Note: Role is full-time, fixed term (2 years), based in London.
