Responsibilities
- Develop reusable map canvases and layer systems for raster imagery, vector features, terrain, and analytical overlays.
- Build layer discovery, grouping, ordering, visibility, opacity, legends, styling, persistent workspace state, and resilient refresh behavior.
- Implement drawing, measurement, spatial selection, feature inspection, coordinate readouts, filtering, map export, temporal exploration, imagery comparison, and linked map/table interactions.
- Extend mapping libraries with custom layers, controls, picking behavior, and rendering logic below the React component layer when needed.
- Integrate COGs, PMTiles, GeoParquet, and Arrow-based sources with viewport-aware loading, cancellation, caching, and progressive feedback.
- Profile and optimize CPU, GPU, network, and memory usage using level-of-detail strategies, background processing, and controlled layer updates.
- Collaborate with UX designers, analysts, backend engineers, and domain experts on cartography, accessibility, interaction quality, component examples, browser tests, and performance checks.
Requirements
- Several years of experience building sophisticated production interfaces with TypeScript and React.
- Substantial experience with web mapping or geospatial visualization using tools such as MapLibre, deck.gl, Mapbox GL, OpenLayers, or CesiumJS.
- Experience extending mapping libraries or building reusable visualization components beyond embedding a standard map.
- Strong understanding of frontend state, asynchronous data loading, browser rendering, and performance profiling.
- Familiarity with WebGL concepts and the performance costs of geometry processing, GPU buffers, large textures, and frequent layer updates.
- Good geospatial fundamentals, including projections, coordinate systems, vector tiles, raster imagery, scale, and spatial accuracy.
- Care for cartography and interaction details, including readable symbology, useful legends, keyboard access, and clear loading and error states.
- Clear English communication, collaboration skills, and eligibility to work in Germany.
- Preferred experience includes custom deck.gl layers, shaders/GLSL, luma.gl, WebGPU, GeoArrow, loaders.gl, DuckDB-WASM, Web Workers, kepler.gl, CARTO, TanStack Query/Store/Router, Tailwind CSS, Storybook, Playwright, terrain and 3D visualization, professional GIS tools, military mapping standards, defense or intelligence environments, open-source mapping, German, offline applications, and self-hosted applications.
Benefits
- Remote-first work in Germany with regular team sessions in Berlin and occasional sessions in Frankfurt and Munich.
- 30 days of vacation, equipment support, and learning support.
- Opportunity to shape a substantial web GIS and shared map platform and own components used across the platform.
- Technically demanding work across interaction design, cartography, browser performance, and GPU rendering.
- Direct access to designers and GEOINT specialists.
