Senior Software Engineer - Distributed Systems

Decentriq is the rising leader in data-clean-room technology. With Decentriq, advertisers, retailers, and publishers securely collaborate on 1st-party data for optimal audience targeting and campaign measurement. Headquartered in Zürich, Decentriq is trusted by renowned institutions in the DACH market and beyond, such as RTL Ad Alliance, Publicis Media, and PostFinance.

Our analytics & ML pipelines are the heartbeat of this platform. Built in Python (pandas) and Apache Spark, they run either in Databricks workspaces or on our own Spark clusters deployed inside confidential-computing enclaves. We are looking for a Senior Software / Data Engineer (≥ 80 %, start as soon as possible) to take end-to-end ownership of these pipelines, raise their resilience to the next level, and push the boundaries of privacy-preserving machine-learning for AdTech. The role can be fully remote (± 4 h CET) or based in our Zürich / Berlin office.

Would you like to help us make the advertising industry ready for the 1st-party era? Then we’d love to hear from you!

Tasks

• Own, Design & Operate Data Pipelines – Take full responsibility for all pandas- and Spark-based pipelines, from development through production and monitoring.
• Advance our ML Models – Improve and productionise models for AdTech use-cases such as look-a-like modelling, audience expansion, and campaign measurement.
• Engineer for the Invisible – Because data inside confidential enclaves is literally invisible (even to root), build extra-robust validation at the data source, exhaustive test coverage, and self-healing jobs to guarantee reliability.
• Collaborate Cross-Functionally – Work closely with data scientists, backend engineers (Rust), and product teams to ship features end-to-end.
• AI-Powered Productivity – Leverage LLM-based code assistants, design generators, and test-automation tools to move faster and raise the quality bar. Share your workflows with the team
• Drive Continuous Improvement – Profile, benchmark, and tune Spark workloads, introduce best practices in orchestration & observability, and keep our tech stack future-proof.

Decentriq, the “Switzerland of data”, is a confidential data collaboration platform. By enforcing compliance and control with advanced privacy technologies, it helps enterprises scale data collaborations across organizational boundaries and unlock value from data that would otherwise be too sensitive to use.

Designed for both data scientists and business users, collaborators use Decentriq’s data clean rooms to analyze sensitive data without sharing it. Powered by confidential computing, data remains encrypted throughout its lifecycle and is verifiably never accessible to another party — not to us, and not even to the cloud provider. Combined with smooth collaboration workflows, fully flexible analysis and maximum interoperability with other technologies, Decentriq makes “sharing without sharing” a scalable strategy.

Decentriq powers data collaboration in the world’s most privacy- and compliance-conscious industries, including media, healthcare, banking, and the public sector.
