About the Project

You’ll be working on a large-scale maritime data intelligence platform focused on fleet tracking, data fusion, and real-time analytics.
The system ingests and processes multiple data sources (e.g. telemetry streams, geospatial signals, external datasets) and applies advanced analytics and AI models to generate actionable insights.
A core part of the product is a data-heavy interface that enables users to monitor vessel activity, explore complex datasets, and detect patterns or anomalies in real time.
About the Role
We’re looking for a Fullstack Engineer (React + Node.js) with a strong frontend focus.
You’ll be building complex, data-heavy user interfaces for analytics, visualization, and real-time monitoring, while also contributing to backend services that power the platform.
The role is focused on working with large-scale data, interactive dashboards, and real-time systems in a high-performance environment.
Responsibilities

* Build and maintain complex frontend applications using React.js (TypeScript)

LLM-powered
coding tools
Nice to have

* Experience with real-time systems (WebSockets, streaming architectures)
* Experience with data visualization and analytics interfaces
