CTO Belgium

At Breakmark, we're partnering with one of the fastest-growing companies in enterprise AI to hire a CTO for Belgium and Luxembourg.

The company is building the infrastructure that enables large enterprises to design, deploy, and manage AI agents across complex business workflows—powering customer and employee interactions through voice, chat, email, and back-office systems in any language or market.

The Opportunity

This is a rare opportunity to join at an early stage in a role that combines the responsibilities of a technical leader, customer-facing executive, and hands-on engineer.

As Site CTO, you'll own the technical strategy for your region, partnering with enterprise customers while building the local technical organisation from the ground up. You'll work at the intersection of Engineering, Product, Sales, and Customer Success, helping shape both customer outcomes and the company's long-term regional strategy.

This is far more than a traditional CTO position—you'll move seamlessly between executive architecture conversations, technical leadership, and writing production code when needed.
