About Ketch

Ketch is redefining responsible data use for the AI era. The Ketch Data Permissioning Platform is the new layer of business technology that helps brands collect, control, and activate permissioned, privacy-safe data across every device, system, and third-party app. Brands around the world use Ketch to simplify privacy and consent operations, increase revenue from advertising, data, and AI initiatives, and build trust with customers and partners.

We are hiring a UK-based, French-speaking Technical Support Engineer to provide high-quality technical support to Ketch customers and partner closely with our Professional Services team on technical conversations, solutions, and troubleshooting during implementations. This role balances reactive support work with proactive engagement -- joining the services team in technical conversations and working directly with customers on technical solutions and troubleshooting.

This is a hands-on technical role. You will work directly with customer engineering teams, developers, and IT stakeholders to resolve complex technical issues across Ketch's platform. You will also support our PS team during customer implementations as the technical expert in the room.
