Who we are: ChartHop is an AI-native HR & Organizational Intelligence platform, connecting your people and business data in one technology to deliver performance, engagement, HRIS, compensation, org planning and analytics. Our product brings transparency to organizations through analytics, connected business data, and highly configurable HR workflows. Our clients include Sweetgreen, 1Password, Zapier, and Headspace. We are looking for a Staff Software Engineer (Technical Lead) to help evolve one of ChartHop's most business-critical product areas.
