Company

Defense and intelligence contractor building operator-facing platforms with AI-native tooling for high-stakes decision environments.

What you will do

• Own interactive front-end for two integrated products: rendering geospatial trade-offs, timelines, rationale for operators and model validation outcomes for analysts.
• Build real-time interfaces updating from streaming data via WebSockets, presenting complex analytical outputs like ranked alternatives and diagnostics.
• Enable operator interaction to interrogate system reasoning, override suggestions, explore alternatives, and build trust through the interface.
• Integrate with RESTful/GraphQL APIs, manage state for asynchronous data flows in a rapid development environment.
• Collaborate in a small elite team at the technical frontier, delivering clarity for actionable decisions.

Requirements

• 5+ years building interactive, data-dense web apps with React and TypeScript
• Experience with geospatial libraries (CesiumJS, Mapbox GL, Deck.gl, Leaflet) for dynamic entities and time-series on maps
• Real-time interfaces from streaming sources (WebSockets, server-sent events)
• Integrating front-end with REST/GraphQL APIs and state management
• Designing interfaces for complex outputs interpretable by non-technical operators
• Ability to obtain TS/SCI clearance with polygraph
• Bachelor's in CS, Software Engineering, HCI or 8+ years professional experience

Nice to have

• Operator-in-the-loop interfaces for time-critical decisions
• Data viz libraries (D3.js, Recharts, Plotly) for charts and timelines
• Products for defense, intelligence, national security
• Operational visualization or decision-support interfaces

Culture & Benefits

• Health, life, disability, financial, retirement benefits, paid leave, professional development, tuition assistance.
• Work-life programs, dependent care, recognition awards for performance and values.
• People-first culture prioritizing collaboration, cameras on in virtual meetings.
• Remote with occasional in-person at facilities; hybrid/onsite options based on role needs.
