Senior Software Engineer

KBR is seeking a Senior Software Engineer to design, develop, and maintain out frontend situational awareness, analysis, and planning tool suite. The successful candidate will work across the full application stack, from interactive 3D geospatial interfaces to real-time data services and local persistence. This role is well suited to an engineer who enjoys solving difficult problems involving high-volume data, responsive user interfaces, distributed systems, disconnected operations, and mission-critical software.

• →Design and implement new common operating picture tools, workflows, and platform capabilities.
• →Develop responsive, accessible user interfaces using React, TypeScript, Next.js, and Ant Design.
• →Build and maintain interactive 2D and 3D geospatial experiences using CesiumJS, ground data, air data, satellite data, terrain, imagery, and vector layers.
• →Extend the framework’s modular tool architecture, including dynamic tool loading, configuration, docking layouts, and RPC-based communication.
• →Develop backend APIs and supporting services using Node.js, Fastify, Express, TypeScript, REST, and server-sent events.
• →Integrate real-time operational data from multiple sources, including tracking, sensor, communications, environmental, and situational awareness systems.
• →Design and optimize client-side and server-side data flows for real-time, historical, and time-windowed geospatial data.
• →Work with MongoDB, Redis, SQLite, IndexedDB, and Dexie-based offline data stores.
• →Implement synchronization, caching, retry, batching, idempotency, and offline/online reconciliation strategies.
• →Build software that functions reliably in disconnected, degraded, and bandwidth-constrained environments.
• →Contribute to Electron desktop packaging, deployment, and local service integration.
• →Improve system performance, observability, reliability, security, and maintainability.
• →Participate in architecture discussions, technical design reviews, code reviews, and engineering planning.
• →Create automated tests and maintain type-checking, linting, build, and release quality gates.
• →Collaborate with product owners, domain experts, operators, and other engineers to translate operational needs into usable software.

• Bachelor's degree in Computer Science, Software Engineering, or a related technical discipline, or equivalent professional experience.
• Seven or more years of professional software engineering experience.
• Strong professional experience with TypeScript and JavaScript.
• Strong experience building production React applications.
• Experience designing and implementing backend services and APIs with Node.js.
• Experience with relational or document-oriented databases, preferably MongoDB, Postgres DB, Arango DB or similar.
• Demonstrated ability to work across frontend, backend, data, and deployment concerns.
• Experience writing maintainable, tested, production-quality code.
• Strong understanding of software architecture, API design, error handling, logging, and operational diagnostics.
• Ability to troubleshoot complex problems across multiple services and runtime environments.
• Excellent written and verbal communication skills.
• Ability to work independently while collaborating effectively with a multidisciplinary engineering team.

• Experience with CesiumJS, Leaflet, geospatial databases, GIS, or spatial indexing.
• Experience building desktop applications with Electron.
• Experience with offline-first or disconnected operations.
• Experience with IndexedDB, Dexie, SQLite, Redis, or client-side synchronization.
• Experience with real-time streaming protocols such as SSE, WebSockets, UDP, or TCP.
• Experience with military, aviation, emergency management, public safety, or other operational data systems.
• Experience with Docker, Docker Compose, Kubernetes, CI/CD, and production release automation.
• Experience with performance optimization for high-volume visualizations and streaming data.
• Experience working in environments requiring formal security, quality, or configuration-management processes.
• Experience mentoring engineers and leading technical work from design through delivery.
