The ideal candidate combines strong React and TypeScript development skills with a solid understanding of UI/UX principles, accessibility, automated testing, APIs, and modern software development practices. Success in this role means delivering interfaces that are intuitive for users, accessible across devices and audiences, well tested, and maintainable for the engineering teams responsible for continuing to enhance them.

Design, build, and maintain production web applications and user interfaces using React and TypeScript.
Develop reusable React components using modern patterns, including hooks and component composition.
Translate UI/UX designs and product requirements into responsive, accessible, production-ready applications.
Build interfaces using semantic HTML and modern CSS practices.
Develop maintainable styling solutions across technologies such as Sass, Material UI (MUI), USWDS, StyleX, or comparable frameworks.
Work closely with UI/UX designers to refine user flows, maintain visual consistency, and ensure designs can be effectively implemented.
Integrate front-end applications with REST/JSON APIs and backend services.
Implement asynchronous application behavior, including loading states, error handling, pagination, and authenticated requests.
Develop automated unit, component, integration, and end-to-end tests using technologies such as Vitest, Jest, React Testing Library, Playwright, or comparable tools.
Participate in Git-based software development workflows involving branching, merge requests, pull requests, code reviews, and release processes.
Work with CI/CD pipelines to support automated testing, application builds, and deployment.
Use modern front-end build tools and package-management technologies such as Vite, Yarn, npm, and private package registries.
Participate in technical design discussions and evaluate implementation approaches based on usability, maintainability, performance, schedule, and technical constraints.
Collaborate with backend engineers, systems engineers, analysts, product stakeholders, and other technical team members.
Participate in code reviews and help maintain strong front-end engineering and development standards.
Troubleshoot and resolve application, integration, browser, performance, and user-interface issues.

What You Will Bring Required Qualifications

Bachelor's degree in Computer Science, Engineering, Information Technology, or a related technical field.
3+ years of professional experience developing production web applications using React and TypeScript.
Strong hands-on experience with modern React development, including hooks, reusable components, and composition patterns.

Strong HTML and CSS fundamentals, including semantic markup, responsive design, layouts, and accessibility.
Experience integrating front-end applications with REST/JSON APIs.
Experience managing asynchronous application behavior, including loading states, error handling, pagination, and authenticated requests.

Experience with end-to-end testing technologies such as Playwright, Cypress, or comparable frameworks.
Professional experience using Git in a collaborative software development environment, including branching and code-review workflows.
Experience working with CI/CD pipelines as part of modern software-development and deployment practices.
Familiarity with modern build and package-management technologies such as Vite, npm, or Yarn.
Strong communication and collaboration skills and the ability to work effectively with designers, engineers, and other stakeholders.
Ability to obtain and maintain a U.S. Government security clearance.

Preferred Qualifications

Experience building or contributing to reusable component libraries or enterprise design systems.
Experience with design-system technologies and approaches such as design tokens, theming, Storybook, or headless UI components.
Experience with Material UI (MUI), USWDS, Sass, StyleX, or similar front-end technologies.
Experience working closely with UI/UX designers to translate designs into reusable production components.
Experience building complex forms or data-intensive user interfaces involving filtering, searching, tables, or data visualization.
Experience with technologies such as Zod, TanStack Form, or TanStack Table.
Experience with front-end state-management technologies such as Zustand or comparable tools.
Familiarity with reactive development patterns or technologies such as RxJS.
Experience with modern TypeScript development patterns, including discriminated unions, exhaustive matching, or typed functional programming.
Experience with Astro or another static-site generation framework.
Experience deploying front-end applications within AWS environments, including technologies such as Amazon S3 and CloudFront.
Familiarity with SSO, authentication, authorization, or edge-authentication patterns.
Experience supporting applications within federal government, regulated, or security-conscious environments.
