Job summary

Orcrist Technologies GmbH is seeking an experienced frontend engineer to build the web GIS experience analysts use to explore imagery, combine layers, and understand spatial and temporal relationships. You will work primarily in TypeScript and React, with MapLibre and deck.gl at the center of a highly customised map platform.

Your work will cover precise analyst tools and the rendering code that keeps complex maps usable, bringing desktop GIS capabilities into the browser and expanding the

Qualifications

• Several years building production interfaces with TypeScript and React.
• Substantial experience with web mapping or geospatial visualization, using MapLibre, deck.gl, Mapbox GL, OpenLayers, CesiumJS, or comparable tools.
• 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 practical costs of geometry processing, GPU buffers, large textures, and frequent layer updates.
• Good geospatial fundamentals: 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 communication in English and an ability to collaborate with backend engineers, designers, and domain experts. Eligible to work in Germany.

Responsibilities

• Develop a reusable map canvas and layer system for raster imagery, vector features, terrain, and analytical overlays, using MapLibre and deck.gl.
• Build layer discovery, grouping, ordering, visibility, opacity, legends, styling, and persistent workspace state, including predictable behavior when sources refresh or fail.
• Implement GIS interactions such as drawing, measurement, spatial selection, feature inspection, coordinate readouts, filtering, and map export.
• Create temporal exploration tools, imagery comparison views, and linked map/table interactions that make complex analytical results understandable.
• Extend mapping libraries with custom layers, controls, picking behavior, and rendering logic. Work below the React component layer when the interaction or performance requirement calls for it.
• Integrate COGs, PMTiles, GeoParquet, and Arrow-based data sources with viewport-aware loading, cancellation, caching, and progressive feedback.
• Profile CPU, GPU, network, and memory usage. Keep panning, zooming, and interaction responsive through sensible level-of-detail strategies, background processing, and controlled layer updates.
• Work closely with UX designers and analysts on cartography, accessibility, and interaction quality. Maintain component examples, browser tests, and performance checks within Sentinel’s shared UI system.
