Job Title-Principal Software Architect

Role Purpose
The Principal Software Architect is the senior technical authority for application and software architecture across Vistra's global technology estate. This role defines the architectural vision, design standards, and engineering patterns that underpin Vistra's enterprise platforms, digital products, and client-facing services — ensuring they are scalable, resilient, secure, and aligned to Vistra's platform-led, AI-enabled operating model.

Reporting to the EVP, IT Architecture & Engineering, this role bridges strategy and execution: translating enterprise architecture direction into actionable software design decisions, reference architectures, and engineering guardrails that accelerate delivery teams while maintaining architectural integrity. The Principal Software Architect is expected to be hands-on — leading by example through design authority, code-level credibility, and deep technical engagement with engineering teams across regions.





This is not a people-management role by default; it is a principal-level individual contributor with significant influence over technical direction, engineering culture, and platform outcomes across the enterprise.
