Description

Would you like to join the leading international intergovernmental organization? We are looking for a Senior Frontend Developer to contribute on the design and implementation of advanced, interactive geospatial visualizations and vector time-series (trajectory) experiences in the maritime web platform. You will own complex UI components built with React and WebGL, delivering performant, reliable, and accessible interfaces that help users explore spatial-temporal maritime data at scale. The team works in a design-driven methodology: you will collaborate closely with product and UX to prototype, iterate, and validate user experiences before and during implementation. You will partner with product, design, backend/data, DevSecOps, and QA to ship features end-to-end, from technical discovery and solution design through implementation, testing, and production operation. You will champion frontend engineering quality, performance, and secure-by-default practices within an Azure-hosted environment. Essential Qualifications & Experience: React, TypeScript, and WebGL Strong TypeScript and modern React Architect, build, and optimize React-based modules and WebGL-powered visualization layers for geospatial and trajectory data. 5+ years building production React apps (hooks, context, performance optimization, code-splitting). 3+ years hands-on with WebGL or related frameworks (deck.gl, luma.gl, regl, three.js, Mapbox GL, Cesium), including shader-based rendering. Geospatial and vector time series Proven experience visualizing geospatial data and trajectories: projections, tiling, feature styling, temporal playback, and interaction patterns (filtering, brushing, path editing). Familiarity with GeoJSON, vector tiles, and projected/geographical coordinate systems. Web app fundamentals Ensure cross-browser compatibility, accessibility (WCAG), responsive layouts, and robust error handling/session management. Excellent communication skills in English and effective cross-functional collaboration. Design-driven delivery Work within a design-driven methodology: contribute to design sprints, build interactive prototypes, participate in usability reviews, and iterate from user feedback. Translate product/UX requirements (e.g., from Figma) into intuitive interactions and informative visualizations. Engineering quality and security Embed quality into delivery with unit/integration tests, visual regression, and performance budgets; collaborate with QA on E2E flows. Understanding of client-side security and OWASP risks (XSS, CSRF, injection) and secure implementation patterns. Performance and reliability Deep understanding of rendering performance: GPU/CPU profiling, minimizing draw calls, buffer/attribute management, culling, LOD, and data streaming. Monitor and improve frontend performance (FPS, memory, bundle size, TTI) and instrument user journeys with observability tooling. Integration and delivery Experience integrating with RESTful APIs (and/or GraphQL), auth flows, and streaming endpoints. Familiarity with CI/CD and quality gates in Azure DevOps (or equivalent), including automated test execution and release pipelines. Communication and collaboration Excellent English proficiency (C1 or higher) for clear written and verbal communication, documentation, and cross-functional collaboration.
