Geospatial Visualization and Real-Time Systems Full-Stack Developer, Senior

Booz Allen Hamilton•Washington, DC

2d•$86,900 - $198,000

About The Position

As a full-stack developer, you know that the most powerful computation in the world is worthless if the person who needs it can't see it, understand it, and act on it in time. You've built interfaces where data arrives continuously, the stakes are high, and the user needs to make a decision, not scroll through a dashboard. You understand that real-time visualization isn't just a front-end problem, it's a systems problem that starts at the WebSocket and ends at the pixel. We are building an operator-facing platform where the interface is inseparable from the product, and we need someone like you to make it real. On this team, you'll own the interactive front-end for two integrated products. One presents operators with constraint-backed planning recommendations. Your job is to render the trade-offs, timelines, rationale, and geospatial context in a way that an operator under pressure can absorb and act on in seconds. The other presents researchers and analysts with the results of formal model composition and execution. Your job is to make validation outcomes, compatibility diagnostics, and evidence artifacts navigable and transparent. In both cases, you're not building a passive display layer, you're building the surface through which people interact with the system, interrogate its reasoning, override its suggestions, and explore alternatives. The interface is where trust is built or lost. You'll join a small, elite team where everyone operates at the technical frontier. You'll be the person on the team who makes everything the system produces visible, explorable, and actionable. You'll build in a rapid development environment with AI-native tooling, delivering clarity that operators can act on without hesitation. Join us. The world can't wait.

Requirements

5+ years of experience building interactive, data-dense web applications using React and TypeScript
Experience with geospatial visualization libraries such as CesiumJS, Mapbox GL, Deck.gl, or Leaflet, including rendering of dynamic entities and time-series data on interactive maps
Experience building real-time interfaces that update continuously from streaming data sources using WebSockets, server-sent events, or push-based architectures
Experience integrating front-end applications with RESTful or GraphQL APIs, including state management for asynchronous and user-driven data flows
Ability to design interfaces that present complex analytical outputs such as ranked alternatives, trade-off surfaces, or diagnostic explanations, in forms that non-technical operators can interpret and act on
Ability to obtain a TS/SCI clearance with a polygraph
Bachelor's degree in a CS, Software Engineering, or Human-Computer Interaction field, or 8+ years of experience working in a professional environment in lieu of a degree

Nice To Haves

Experience building operator-in-the-loop interfaces for time-critical decision environments where latency and clarity directly affect outcomes
Experience with data visualization libraries such as D3.js, Recharts, or Plotly, for rendering charts, timelines, or constraint-trace visualizations
Experience building products for defense, intelligence, or national security customers
Experience working in operational visualization, geospatial applications, or complex decision-support interfaces
