Head of Customer Success

About Clark

Clark is building the trust infrastructure for the AI economy.

We're starting with audit and accounting workflows—high-trust environments where reliability, accuracy, and security matter as much as productivity. Our platform helps firms automate complex workflows, deploy AI safely, and modernize how audit teams operate.

We're building a team that combines deep domain expertise, strong customer execution, and AI-native product thinking to redefine how audit gets done.

We are hiring a Head of Customer Success to own Clark's live customer base and build the foundation for a world-class post-sale organization.

This person will land first, protect the existing customer base from day one, and begin recruiting the customer success bench as Clark scales. You will own customer health, renewals, adoption, implementation quality, and the operating cadence that keeps customers successful.

This is a hands-on leadership role. You should be comfortable both building the function and personally engaging with customers.

Clark's customers are adopting AI in high-trust workflows where accuracy, reliability, and change management are critical.

Customer success is not simply account management. It is how we ensure customers reach value, expand usage, and trust Clark as a long-term partner.
