Описание вакансии

As Preply scales its AI-powered learning platform, we’re looking for an experienced Senior ML Engineer to help productionize machine learning systems with high reliability, performance, and observability. You’ll work at the intersection of ML, data engineering, and cloud infrastructure enabling fast, secure, and reproducible model development from training to deployment.
You’ll collaborate closely with ML Scientists, Backend Engineers, and Data Engineers to shape the foundations of our ML lifecycle.

What you’ll be doing

• Build and maintain ML pipelines for training, evaluation, and deployment using tools like Databricks, MLFlow, Airflow, DBT, Sagemaker, Tecton
• Support AI scientist creating reproducible, containerized model training environments (on-demand and scheduled), and manage compute at scale (e.g., spot/GPU autoscaling)
• Define and implement observability and alerting for ML systems (model drift, data quality, feature coverage, etc.)
• Design and scale data ingestion and feature transformation flows using batch (e.g., Spark/BigQuery) and streaming (Kafka or equivalent)
• Contribute to internal Python libraries and platform tooling that accelerate experimentation and deployment for all model teams
• Ensure ML services are modular, testable, and monitored from day one
• Exploration and productionization of LLM-based features (e.g., retrieval pipelines, prompt evaluation, model serving)

What we’re looking for

• Proven experience designing and deploying ML systems in production (5+ years in relevant roles)
• Proficiency in Python and SQL, and orchestration tools (Airflow, Kubeflow, Dagster, etc.)
• Experience with modern cloud platforms (preferably GCP or AWS), Kubernetes, and CI/CD workflows
• Understanding of ML model lifecycles: training, validation, deployment, and monitoring
• Strong DevOps practices: Git, IaC (Terraform), logging/observability, containerization (Docker/K8s)
• Ability to work independently with ML Scientists and mentor peers in reliability, testing, and delivery. Product impact driven.
• Exposure to LLM serving, vector databases, or GenAI-powered product flows
