Geospatial Frontend Engineer

Orcrist is building a next generation data intelligence platform using cutting-edge technologies. We're handling petabyte-scale data with sub-second queries. Our product is a Kubernetes‑based platform delivered as B2B SaaS or as a self‑hosted on‑prem solution, including air‑gapped deployments. We enable customers across defense, law enforcement, and enterprise to turn mission-critical data into actionable intelligence.

Role

Build the web GIS experience analysts use to explore imagery, combine layers, and understand spatial and temporal relationships. You'll work primarily in TypeScript and React, with MapLibre and deck.gl at the center of a highly customised map platform.

Your work will range from precise, responsive analyst tools to the rendering and data-loading code that keeps complex maps usable. You'll bring capabilities familiar from desktop GIS tools such as QGIS and ArcGIS Pro into the browser, continuously expanding the map platform's rich feature set while keeping interactions coherent and responsive. You'll extend the existing Sentinel frontend and help establish reusable map and layer components for multiple applications.

What you'll do

• 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.

About you

• Several years building sophisticated 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.
