About the role

Key responsibilities & impact

Contribute on the design and implementation of advanced, interactive geospatial visualizations and vector time-series experiences in the maritime web platform.
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.
Collaborate closely with product and UX to prototype, iterate, and validate user experiences before and during implementation.
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.
Champion frontend engineering quality, performance, and secure-by-default practices within an Azure-hosted environment.

Requirements

What you’ll need

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.
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.
Ensure cross-browser compatibility, accessibility (WCAG), responsive layouts, and robust error handling/session management.
Excellent communication skills in English and effective cross-functional collaboration.
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.
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.
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.
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.
Excellent English proficiency (C1 or higher) for clear written and verbal communication, documentation, and cross-functional collaboration.
