• 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.
