MiddleSenior MLMLOps Engineer

N-iX is looking for a Senior Machine Learning Engineer in Kyiv. You will be responsible for designing developing and deploying machine learning models at scale within the Palantir Foundry will collaborate closely with data scientists MLOps engineers and data engineers to build robust production-grade ML workflowsfrom data preparation and feature engineering to model training evaluation deployment and monitoring.

Key Responsibilities

• Design and implement scalable ML models for use in predictive analytics forecasting and classification tasks.
• Work with Palantir Foundry to build end-to-end ML pipelines including custom Python code Foundry Functions and Ontology-aware feature generation.
• Collaborate with Data Engineers to ensure high-quality model-ready data flows from ingestion to inference.
• Operationalize models using industry best practices for versioning reproducibility and monitoring (e.g. via MLflow or native Foundry tools).
• Contribute to MLOps automation including CI/CD for ML drift detection retraining pipelines and evaluation dashboards.
• Partner with business stakeholders and domain experts to translate scientific or commercial hypotheses into model-based solutions.
• Apply rigorous experimentation and statistical validation to ensure models are explainable generalizable and regulatory-compliant.
