About OPEN Data Jobs
OPEN Data Jobs (ODJ) is built to craft data careers. We connect high-potential data, AI, and software professionals with meaningful work on the cutting edge of the federal sector, and our aim reaches beyond any single opening: to help you understand your strengths, find the right role, and grow throughout your career.
ODJ is organized around Roles and Openings. A Role is a durable career type, such as Data Engineer or AI Engineer: it describes the work, the skills that count, and where the path can lead. An Opening is a specific position hiring right now, with a level, a location, and an application. Roles help you see where you fit; from there, there is more than one way to move.
Today, you can apply to any Opening that fits you through our secure application system. You can also register for a Role to express interest in that broader category of work. A Role registration is not an application to every future Opening.
The work
Front-End Developers build the browser experience people use to understand information and complete work. Working in modern component frameworks such as React, they translate user and product needs into components, interactions, forms, navigation, and stateful workflows using TypeScript or JavaScript, HTML, and CSS.
The role owns more than appearance. You structure state and data flow, integrate APIs, handle loading and failure states, protect browser-side boundaries, and test behavior across users, devices, and browsers. You use semantic HTML first and add Accessible Rich Internet Applications (ARIA) patterns when native elements do not provide the interaction a component needs.
Accessibility and performance are part of implementation, not finishing steps. Front-End Developers work with designers, researchers, content specialists, back-end engineers, security teams, and users to create interfaces that are understandable, keyboard-operable, resilient, responsive, and maintainable.
What you'll build
- Pages, component libraries, design-system implementations, and reusable component patterns in a modern framework such as React.
- Forms, navigation, tables, dashboards, search, filtering, and complex stateful workflows.
- API integrations with clear loading, empty, success, validation, and error states.
- Accessible interactions tested with semantic markup, keyboard use, focus management, and assistive technologies.
- Unit, component, integration, and browser tests plus performance and client-side security improvements.
Who you are
You care how an interface looks, but you judge quality by whether people can understand it and complete their work. You notice unclear state, fragile component boundaries, inconsistent behavior, inaccessible interactions, and unnecessary complexity.
You collaborate closely and test assumptions with evidence. You can explain browser constraints, preserve design intent, negotiate API needs with back-end teams, and improve a codebase without turning every change into a rewrite.
What you bring
- Professional experience with a modern component framework (React, Angular, Vue, or equivalent), TypeScript or JavaScript, semantic HTML, modern CSS, and component-based design.
- Sound judgment about state structure, data flow, reusable components, forms, routing, and API integration.
- Working knowledge of Web Content Accessibility Guidelines (WCAG), keyboard interaction, focus management, and ARIA patterns.
- Experience with automated tests, browser developer tools, version control, code review, and delivery pipelines.
- Ability to diagnose rendering, network, performance, compatibility, and client-side security problems.
Requirements
What openings may require
An opening may specify a React framework, state-management approach, build tool, test stack, design system, visualization library, content-management platform, or browser-support matrix. Some work may require Section 508 conformance, documented accessibility testing, internationalization, or performance targets.
AI-enabled interfaces may add streaming responses, citations, feedback controls, human review steps, and clear communication of system status and uncertainty. Those requirements remain interface engineering concerns. Model behavior, evaluation, and AI-specific risk decisions belong with AI specialists and the broader product team.
