Responsibilities

• 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: 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.
• Drive Continuous Improvement: Profile, benchmark, and tune Spark workloads, introduce best practices in orchestration & observability, and keep our tech stack future-proof.

Requirements

• Must have:

  • Bachelor/Master/PhD in Computer Science, Data Engineering, or a related field and 5+ years of professional experience.
  • Expert-level Python plus solid hands-on experience with pandas, PySpark/Scala Spark, and distributed-data processing.
  • Proven track record building resilient, production-grade data pipelines with rigorous data-quality and validation checks.
  • Experience running workloads in Databricks, Spark on Kubernetes, or other cloud/on-prem big-data platforms.

• Plus:

  • Working knowledge of ML lifecycle and model serving; familiarity with techniques for audience segmentation or look-a-like modelling.
  • Exposure to confidential computing, secure enclaves, homomorphic encryption, or similar privacy-preserving tech.
  • Rust proficiency (used for backend services and compute-heavy client-side modules).
  • Data-platform skills: operating Spark clusters, job schedulers, or orchestration frameworks (Airflow, Dagster, custom schedulers).

Benefits

• Join Decentriq's Engineering team as an individual contributor and earn growing responsibilities.
• Opportunity to create, shape, and benefit from a young company.
• An amazing and fun team that is distributed all over Europe.
• Competitive salary.
• A lot of opportunities for self-development.
• No need for a formal motivational letter; just send your CV along with a few bullet points about why you're excited to work with us. We look forward to your application!
