Senior Machine Learning Engineer

About the role

The Senior Machine Learning Engineer is responsible for designing, building and operating a unified machine learning infrastructure that standardises the model lifecycle from research to production. The role bridges the gap between batch-oriented data in Snowflake and real-time inference on Kubernetes, applying high software engineering standards and reducing implementation redundancy across data science squads.

Key responsibilities

• Design and maintain the core ML platform architecture, integrating Snowflake/Snowpark with Kubernetes for hybrid workloads.
• Deliver end-to-end data science products such as flight revenue forecasting, customer retention and ground operations.
• Automate ML pipelines covering data ingestion, model training and continuous deployment with Apache Airflow and GitLab CI/GitHub Actions.
• Build and manage a centralised Feature Store and Model Registry in Snowflake.
• Implement observability for model performance, data drift and system health using Prometheus, Grafana and Evidently AI.
• Develop reusable FastAPI or gRPC service wrappers for real-time model serving.
• Set up "paved road" workflows (CI/CD, unit testing, modular code) for the wider data science team.

Required profile

• Bachelor's or Master's degree in Computer Science, Software Engineering or a related field; fluent English.
• Minimum 6-8 years of experience in data science, MLOps, platform engineering or DevOps for machine learning, including 1-2 years in the aviation domain (airline or vendor).
• Deep understanding of aviation systems such as PNRs, e-tickets and revenue management logic (yield and inventory control).
• Ability to influence architectural decisions and engineering culture without direct authority.

Required skills

• Mastery of Kubernetes, Docker and Infrastructure as Code (Terraform)
• Expert Python (OOP, modular design) and SQL
• Serving models with LightGBM, XGBoost, TensorFlow and PyTorch
• Hands-on experience with Snowflake/Snowpark and Airflow
• Proficiency in MS Office
