Turn data into impact!

JobCloud connects hundreds of thousands of job seekers with employers every day and behind every product decision is data. As our next Senior Data Engineer, you'll own the warehouse stack that makes that possible: well-designed data models, performant SQL, and a single source of truth that teams across the company actually rely on.

What sets you apart is that you're equally at home in a technical deep-dive and a business requirements discussion - you don't just model what you're told, you understand why it matters and aren't afraid to challenge assumptions when something doesn't add up. If you want real ownership, an established stack to evolve, and colleagues who'll push you to do your best work, this is the role.

We are looking for someone based in or willing to work from our offices in Zurich or Geneva.
