This is our most senior individual-contributor architecture role. The Senior Principal is the technical authority for application architecture across the platform: someone who sets enterprise-level architecture direction without needing a team to do it, and who is close enough to the code, system design, and production tradeoffs to make that direction credible to engineers.

This role has overlap with enterprise architecture, and a background in enterprise architecture is a plus, but the work is closer to the code, system design, engineering execution, AI development improvements, vendor integration, and production tradeoffs than to enterprise architecture theater.

Stellarus generally takes a build-over-buy approach
