JOB ID #936

Ad Hoc is a technology company that empowers organizations to deliver scalable, impactful digital services. Using modern, agile methods, our team creates products that meet people's needs and transform their experience of government.

Our collaborations have shaped some of the defining moments in public-sector service delivery. We've helped build products that connect Veterans to tailored services, help millions access affordable health care, and support important programs like Head Start. As we work with agencies to deliver critical services, we're also changing how the government approaches technology.

Our culture, communications, and tools are built for remote work, enabling us to bring together top talent nationwide. At Ad Hoc, remote life empowers our teams to design work environments that fit their lives and that foster flexibility and collaboration to achieve positive outcomes for our customers.

Ad Hoc values acceptance, accountability, and humility. We aren't heroes. We learn from our mistakes and improve the process for the next time. We build small, inclusive teams to collaborate closely with our partners to solve the right problems and deliver software that works.

The Veterans Affairs business unit helps transform the VA into a modern digital services organization where Veteran outcomes are at the center of every effort. We partner with the VA to design and deliver seamless user experiences for Veterans, their families and caregivers, and VA employees. By applying better practices in service design, product management, and technology, we enable the VA to increase the use, quality, and reliability of services and decrease the time Veterans spend waiting for outcomes.

This role supports the Veterans Enrollment System Enrollment Eligibility (VESEE) program for the Department of Veterans Affairs (VA) Office of Information & Technology. These systems support Veteran health care eligibility and enrollment and serve more than 16,000 users across the Health Eligibility Center and VHA Office of Community Care.
