Senior Data Engineer

Turn data into impact!

Job Cloud 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 infrastructure that makes that possible: scalable pipelines, clean data models, and a warehouse that teams across the company actually trust.

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 build what you're told, you understand why it matters and aren't afraid to push back when something doesn't add up. If you want ownership, a modern stack, and colleagues who'll challenge 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.

• 3+ years of experience in data warehouse development and ETL, ideally with Redshift and Matillion
• Python skills and experience with Infrastructure as Code and Ansible
• Solid AWS knowledge across S3, Redshift, and Lambda, including cloud optimization
• Advanced SQL and data modeling capabilities with a focus on scalability and performance
• Experience with data streaming (e.g., Apache Kafka) and integrating diverse APIs and data sources
• Familiarity with BI tools, preferably Tableau, to make complex data accessible to business stakeholders
• Strong business understanding combined with structured analytical thinking — you translate requirements into technical solutions, ask the right questions, and aren't afraid to challenge assumptions
• Proactive and hands‑on communicator who bridges the gap between data and decision‑makers
• Fluent in English, German is a plus

• Develop and operate robust ETL pipelines using Matillion, supported by Infrastructure as Code and Ansible
• Implement AWS Lambda functions for customized data solutions beyond standard ETL capabilities
• Integrate diverse data sources and APIs to centralize enterprise data
• Design sustainable and scalable data models and complex SQL queries for business use cases
• Manage master data to ensure accurate consolidation and consistency across systems
• Operate and optimize the data warehouse infrastructure (Matillion, Redshift, Tableau)
• Collaborate with cross‑functional teams to deliver data‑driven solutions and share knowledge via presentations and documentation

• A senior role with real ownership in a lean team of four: your architecture decisions shape how the whole company uses data
• Flat hierarchy, collaboration at eye level, and the freedom to bring your own ideas and challenge the status quo
• Hybrid work model with flexibility to work remotely and from our modern offices in Zurich or Geneva
• An international company that sees diversity as a strength, with cross‑functional teams and a genuine commitment to inclusion
• Salary between CHF 130'000 and 150'000 gross per year, depending on experience
