You Will Have the Opportunity to
Build and maintain dataset ingestion, cleaning, and versioning pipelines (training, validation, and held-out evaluation sets)
Design and operate labeling workflows, including quality control and inter-annotator agreement tracking
Own dataset testing: coverage analysis, class balance, leakage detection, dataset documentation
Manage dataset versioning and lineage so every model release traces back to exact training data
Partner with data science and product engineering teams on data-sharing boundaries and formats
3+ years data engineering experience; strong Python and SQL
Experience with data versioning tools (DVC, LakeFS, or similar) and pipeline orchestration (Airflow, Dagster, or similar)
Understanding of ML-specific data concerns: train/test leakage, label noise, distribution shift
Rigor in documentation and reproducibility
Stable, growing international company background with an exceptional customer group
Opportunity to improve your professional skills
The newest technology environment
Language course and opportunity for active recreation – kettlebell, football and office massage
Attractive working environment – nice office full of accessories (fruits every day, coffee, breakfast, tea etc.)
