About the Role

**Description**

This is not a maintenance role. This is a reinvention role.

We are looking for a Principal Software Engineer who doesn’t just build systems—but reshapes how they are conceived, delivered, and trusted. Someone who pairs deep technical credibility with architectural vision, and who has the conviction to challenge legacy approaches when the mission demands more.

In this role, you will be a technical provocateur and lead engineer, driving the design and delivery of AI-enabled, agentic, and intelligent software platforms that dramatically accelerate modernization and outcomes. You’ll operate at the highest altitude—setting technical direction, evaluating emerging technologies, and prototyping what’s next—while still diving deep to turn ideas into production-grade reality.

This is a role for builders who bias toward action, who believe disruption can coexist with rigor, and who want to apply cutting-edge AI to the problems that matter most....
