Frontend Lead

United States citizenship and Public Trust eligibility are required. Work on site at a government facility in the Arlington, VA area.

About the role

The Frontend Lead owns the architecture and construction of the web application used by operators in a cyber command center supporting national cyber defense across Critical Infrastructure, State, Local, Tribal and Territorial, and Federal Civilian Executive Branch partners. The successful candidate designs the front-end architecture, builds a substantial share of it, and sets the standards the other interface engineers work to.

Responsibilities

• Own the front-end architecture, including module structure, composition, 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.
• Ensure the application meets Section 508 and WCAG requirements as a condition of delivery.
• Own the automated test approach across component, integration, and end-to-end levels.
• Enforce code quality standards through review, static analysis, and shared conventions.
• Obtain and maintain the training and certifications required for the position; certification currency is tracked and reported to the customer monthly.
• Provide technical direction and code review to the engineers building the interface.
• Break work into deliverable increments and estimate credibly against a fixed delivery date.
• Work with the design function so designs are implementable and applied consistently.
• Work with the service layer engineers on interface contracts and data delivery patterns, and with platform engineers on build and deployment.
• Identify and escalate technical risk affecting the delivery schedule.

Requirements

• 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. Additional years of directly relevant experience may substitute for the degree requirement.
• Public Trust eligibility.
• United States citizenship.

Preferred Qualifications

• Production experience with React and TypeScript specifically; the application is currently expected to be built in React.
• Experience building operational or monitoring interfaces intended for sustained use.
• Experience with micro-frontend composition or equivalent independent-deployment patterns.
• Specific experience with content delivery and static hosting services such as CloudFront and S3, or Azure Front Door and Blob Storage.
• Experience with large-format or shared-display rendering targets.
• Experience delivering software in a government or otherwise regulated environment.
• Experience establishing a design system or component library from scratch.
• IAAP Web Accessibility Specialist, or demonstrable equivalent accessibility practice.
