• Solid understanding of REST API consumption and real-time data patterns.

Responsibilities

• The VANTAGE web client — our primary interface for wargame setup, execution, and after-action review.

Job description

Shape the interface through which military commanders explore the future battlefield.

The VANTAGE frontend is the point where complex operational data becomes human-readable insight — where a commander decides which course of action to take. You will own that experience. Working closely with our simulation engineers and end-users in active military organisations, you will design and build interfaces that are fast, intuitive, and powerful enough to handle multi-domain operational environments at scale.

This is not a typical frontend role. Your users are military planners, naval officers, and AI researchers. Clarity, performance, and trust are the design constraints — not aesthetics alone.

What You Will Work On

• The VANTAGE web client — our primary interface for wargame setup, execution, and after-action review
• Real-time multiplayer visualisation of multi-domain simulation data (land, sea, air, cyber, space, EW)
• AI‑assisted COA comparison interfaces — presenting traceable, evidence‑backed recommendations to commanders
• Scenario editor and unit configuration tools used by military instructors and planners worldwide
• Integration with our REST and MCP APIs to surface live simulation data

Requirements

Essential: Strong proficiency in React and modern TypeScript. Experience building complex, data‑rich web applications. Solid understanding of REST API consumption and real‑time data patterns.

A strong plus: Experience with mapping or geospatial visualisation libraries. Interest in simulation, gaming engines, or data‑heavy dashboards. Any background in defence, security, or mission‑critical software.

Who you are: You care about the end‑user experience deeply. You are comfortable working with ambiguous requirements from non‑technical users and translating them into clean, precise implementations. You want your work to have real‑world impact.
