We are hiring two Senior Principal Software Architects for our Texas team, working on the same team as our Application Architect role. This is a full-time, permanent position based onsite in Plano, Texas, five days a week, with no flexible or remote arrangement. The role provides technical leadership and architectural guidance for a new enterprise platform supporting high-volume customer and transaction operations, with influence over technology choices, engineering standards, and delivery. It is a hands-on architecture leadership position, with approximately 70% of the work focused on code rather than management or advisory work alone.
