Join our community of mission-driven creatives, communicators, strategists, and technologists to challenge the status quo.

You’ll work as part of a cross-functional team of frontend and full-stack engineers, user experience designers and researchers, solution architects, quality assurance specialists, accessibility experts, business analysts, product managers, data analysts, security specialists, and behavioral health subject matter experts. We partner with federal stakeholders to operate and modernize a mission-critical data collection and performance reporting platform used by grantees and program staff.

In this individual contributor role, you will build responsive, accessible, and maintainable interfaces for complex data collection and reporting workflows. You will translate user experience designs into production-ready components, connect interfaces to .NET services and REST APIs, implement client-side validation and workflow behavior, and write automated tests that support dependable releases.

A key part of the work is improving the usability and consistency of an active federal application while it continues to serve current users. You will help modernize legacy interfaces incrementally, strengthen the component and design system, improve performance and accessibility, and collaborate closely with backend engineers, designers, testers, product teams, and users.
