Technical Support Engineer, EMEA (French-speaking)

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.

About the Role

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.

This role reports to the Head of Customer Experience and partners closely with our US support, services, and engineering teams.

What You'll Do

Serve as the primary technical support resource for European customers, owning ticket resolution end-to-end across web technologies, APIs, SDK integrations, and platform configuration
Partner with the Professional Services team on customer implementations -- joining technical scoping calls, troubleshooting integration issues, and providing technical solutions to complex customer environments
Work directly with customer developers, IT teams, and data engineers to diagnose and resolve issues
Use tools like Postman to troubleshoot API calls, inspect requests/responses, and identify root cause
Investigate and resolve issues across JavaScript, HTML, CSS, and front-end behavior
Document fixes, known issues, and reusable solutions for the broader support and services teams
Provide hand-off and continuity coverage to the US and India support teams
Escalate to engineering when appropriate, while owning customer communication and resolution timelines

What We're Looking For

4+ years in a technical support, solutions, or implementation role at a B2B SaaS company (pure software -- not hardware, networking, or systems integration)
Strong working knowledge of JavaScript, HTML, CSS, and APIs
Comfortable using Postman or similar tools to troubleshoot API behavior
Experience administering or supporting SaaS platforms
Genuine technical curiosity -- self-directed learner who digs into product, reads docs, and builds working knowledge of complex systems

UK-based with the right to work in the UK
Flexibility to overlap with US business hours regularly, including evenings
Comfortable working independently in a startup environment with limited playbooks
