Bring your whole self. You will be a senior technical leader within the team responsible for developing, scaling, and maintaining the DXA(Digital Experience Analytics) reporting tool. A primary focus of this role will be driving the strategic migration of the DXA portal from our legacy Backbone framework to our modern, Alchemy-based React framework.

As our team actively works toward achieving FedRAMP compliance for our reporting platform, you will play a critical role in aligning our frontend architecture, data handling, and security practices with federal compliance standards. As a senior member of the team, you will not only write high-quality code but also establish best practices, mentor other developers, and collaborate closely with product and design teams to shape our technical roadmap.
