• Translate user experience designs, prototypes, and acceptance criteria into reusable, accessible, and production-ready components.
• Build complex forms, client-side validation, data tables, workflow interactions, notifications, and reporting interfaces for data-intensive applications.
• Integrate frontend applications with REST APIs, authentication services, analytics, and backend capabilities implemented in .NET.
• Write and maintain unit, integration, regression, and end-to-end tests for user interface behavior and critical workflows.
• Apply semantic HTML, keyboard support, screen-reader compatibility, color and focus requirements, Section 508, and WCAG standards throughout development.
• Improve frontend performance, browser compatibility, error handling, usability, and maintainability through measurement and iterative refinement.
• Participate in Agile planning, estimation, code reviews, demonstrations, release activities, and user acceptance testing support.
• Collaborate with design, accessibility, backend engineering, quality assurance, security, product, and client stakeholders.
• Maintain documentation for components, interaction patterns, build tooling, testing, and frontend development standards.

Required Qualifications:

• Bachelor’s degree in computer science, software engineering, information systems, design technology, or a related field, or equivalent professional experience.
• 3+ years developing and supporting resilient, well-tested web applications using HTML, CSS, and JavaScript or TypeScript, including browser debugging.
• 2+ years integrating REST APIs and JSON, with working knowledge of HTTP and HTTPS/TLS.
• 2+ years using React, Angular, Vue, or a comparable framework to build responsive layouts, reusable components, and complex forms with conditional behavior, client-side validation, and error handling.
• 1+ year applying accessible development practices, including semantic HTML, keyboard navigation, and focus management, with working knowledge of Section 508 or WCAG requirements.
• 1+ year writing automated frontend unit tests, with exposure to integration and end-to-end testing, and using package managers, build tools, and Git-based workflows, including pull requests and code reviews.
• Authorization to work in the United States, ability to perform all work within the United States, and ability to obtain and maintain a favorable Public Trust determination and complete required background screening.

Preferred Qualifications:

• Experience with the U.S. Web Design System or another mature design system, including extending accessible, reusable components.
• Experience incrementally modernizing legacy interfaces within .NET, ASP.NET MVC, or Razor-based applications.
• Experience building data-intensive interfaces, such as configurable data-entry workflows, complex data tables, dashboards, or reporting tools.
• Experience integrating interfaces with federated identity, single sign-on, multifactor authentication, or role-based access.
• Experience improving frontend performance and reliability through monitoring, analytics, error tracking, browser compatibility testing, and automated deployment pipelines.
• Experience supporting federal or public health applications, including familiarity with secure cloud environments, federal security and privacy requirements, or sensitive data handling.
