Why This Role Is Important to Arcadia

Arcadia's platform is the backbone of how partners and customers act on healthcare data at national scale. Principal Engineers are the technical owners of the cross-team initiatives and platform-level outcomes that define what Arcadia's engineering organization is capable of — the engineers others look to when the right answer is structural, not incremental.

A Principal Engineer at Arcadia owns the complete vertical slice: requirements through customer validation, design through long-term operation. They raise the floor for the engineers around them through direct coaching, reusable patterns, and the tooling they leave behind. They define how the team adopts AI as a leverage multiplier — not just for their own productivity, but as a standard the team and the org can adopt.
