Job 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.
