We're looking for a Principal People Success Partner (more commonly referred to as "HRBP") to serve as the strategic HR partner for Toast's R&D organization — a 2,000+ person community spanning Engineering, Product, and Design. You'll report directly to the Senior Director, PSP and operate as a true thought partner to senior leaders, helping shape how we build, develop, and sustain a world-class product and technology organization. This is a high-impact individual contributor role for someone who excels at navigating organizational complexity, influencing without authority, and translating people strategy into practical outcomes.

Champion a culture of clear expectations and candid feedback; help leaders understand what "raising the bar" looks like in practice.
