Senior Data & AI Engineer – Snowflake Zürich

As a Technical Lead, you are responsible for the architecture and implementation of modern data platforms on Snowflake – from target architecture to productive operations. Together with business and IT, you translate business requirements into robust technical solutions and establish Snowflake best practices in your teams.

You build scalable data pipelines with SQL, Python/Snowpark and dbt, using Streams, Tasks, Dynamic Tables and UDFs, and integrate source systems such as SAP, CRM and streaming data. With Snowflake Cortex AI (e.g. Cortex Search, Cortex Analyst, Agents), you implement GenAI and ML use cases directly on the platform.

You ensure quality and cost efficiency through clean data modeling, governance with Snowflake Horizon, role and access concepts as well as performance and cost optimization. You automate deployments with CI/CD and Infrastructure as Code (e.g. Terraform) on AWS or Azure. In sales/presales, you run workshops and PoCs, estimate effort and help shape proposals. You coach colleagues and actively build our Snowflake community in the DACH region.
