• Integrate React applications with Java and .NET backend services and RESTful APIs.
• Build automated tests for the UI, including unit, integration, and end‑to‑end tests.
• Ensure accessibility, responsiveness, and adherence to modern UI best practices.
• Optimize performance through code splitting, lazy loading, and efficient rendering strategies.
• Implement secure front‑end patterns, including dependency hygiene, API input validation, and token handling.
• Review and refactor front‑end code to ensure maintainability and consistent patterns.
• Mentor team members on React, Type Script, testing strategies, and SPA architecture.

• Minimum 5+ years of professional software development, including substantial front‑end experience with React.js.
• Experience owning front‑end architecture or major UI components in production SPA applications.
• Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent experience.
• Ability to obtain or maintain a government security clearance.
• Prior DoD or federal experience is strongly preferred.

• Strong proficiency with React.js, Type Script, SPA architecture, and modern JavaScript tooling.
• Experience with front‑end state management solutions such as Redux, Zustand, Recoil, or Context API.
• Familiarity with build tools such as Webpack, Vite, Babel, or similar.
• Experience consuming RESTful APIs and collaborating with backend developers to shape API contracts.
• Understanding of accessibility and compliance standards common in government systems.
• Experience deploying front‑end applications to AWS services such as S3, Cloud Front, API Gateway, and Cognito.
• Strong troubleshooting skills in UI performance, rendering, and cross‑browser compatibility.
• Self‑directed with the ability to own features from concept to production.

• HTML, CSS, JavaScript, and Type Script.
• React Router and component‑based architecture.
• SPA security patterns for authenticated applications.
• Modern front‑end testing frameworks such as Jest, React Testing Library, and Cypress.
• RESTful API integration patterns.
• Basic backend development in Java or .NET for full‑stack feature work.
• Containerization concepts using Docker.
• CI/CD practices for building, testing, and deploying front‑end assets.
• Agile methodology.
