About Harri

Harri is the first enterprise-ready workforce management platform built for the services vertical. The services vertical faces the greatest technological challenges that exist within the world of Human Capital Management and we believe they deserve a platform built from the ground up as a result. We have experienced a tremendous amount of growth since our 2012 inception and we have no plans on stopping that growth anytime soon. We are passionate about building a team of Service First-driven individuals who want to exceed the expectations of those who experience our brand. 

If you’re a builder, or problem solver, and love the fast pace of a startup, it’s time to meet the Harri family.

However, this leadership role is not about incrementally improving existing customer success & operations, but about fundamentally reimagining our customer experience (CX) through the dual lens of top-notch traditional customer success that aligns with the realities of our customers. A key element of the role is to accelerate the use of autonomous AI agents to be more efficient and better serve our customers. The ideal candidate will possess a deep understanding of customer success, implementation, technical account management,  and customer support along with experience in Agentic AI and a proven track record of deploying scalable AI solutions that deliver measurable business impact and exceptional customer outcomes. This leader will orchestrate a hybrid workforce of human experts and autonomous AI agents, identifying opportunities to augment frontline customer interaction with high-value orchestration and oversight.
