Senior Frontend Architect & Tech Lead (Real-Time UI)

General Dynamics - IT; Arlington (VA); On-site; USD 140,000 - 190,000; Full time

Job summary

General Dynamics - IT is seeking a Frontend Lead to architect and build the web application used by operators in a cyber command center. You will set standards, own the front-end architecture, and lead the team to deliver a performant, accessible interface across partners.

The role requires hands-on React/TypeScript expertise, experience with real-time data streams, and the ability to implement role-based rendering, shared state, and a scalable component library in a government context.

Qualifications

• Senior hands-on experience architecting and building production single-page web applications in a modern component-based framework.
• Experience with modular or independently deployable front-end architectures.
• Experience owning shared application state, including context that persists across functional areas.
• Experience building interfaces driven by continuously updating data over WebSocket, server-sent events, or an equivalent, including reconnection and state recovery.
• Experience implementing role or permission-driven rendering.
• Demonstrated ability to sustain rendering and interaction performance under high-frequency updates and large data volumes.
• Strong proficiency in a statically typed JavaScript environment, modern build tooling, and automated testing practice.
• Working knowledge of Section 508 and WCAG requirements and how to satisfy them in a shared component library.
• Experience providing technical direction and code review to other engineers.
• Technical training, certification, or a degree in a related field, and 5 years of relevant experience.
• Public Trust eligibility.
• United States citizenship is required.
• Work on site at a government facility in the DMV area.

Responsibilities

• Own the front-end architecture, including module structure, routing, build tooling, and dependency management.
• Design the application so functional areas can be developed, tested, and released independently without destabilizing the whole.
• Design and own the shared application state model, including context that persists as a user moves between functional areas.
• Establish and maintain the shared component library and the conventions governing its use.
• Implement consumption of continuously updating data over WebSocket, server-sent event, or comparable streaming interfaces.
• Handle connection lifecycle, authentication on the stream, reconnection, and recovery of state missed during an interruption.
• Implement update strategies that keep the interface responsive under sustained high-frequency change.
• Implement stale, degraded, and disconnected states so the currency of displayed data is always evident.
• Implement rendering driven by user role and permission, so available content and actions are determined by entitlement.
• Implement client-side handling of content-level restrictions supplied by the service layer.
• Ensure entitlement logic is testable and that failures fail closed.
• Profile and optimize rendering, update, and interaction performance against realistic data volumes.
• Ensure the application performs on the managed workstation configuration and restricted browser baseline deployed in the operating environment.
• Support use across multiple simultaneous views and multiple displays, and rendering on large-format shared displays.
