Data Science and Machine Learning Engineer

Job Title: Data Science & Machine Learning Engineer

Location: On-site (Mexico)
Employment Type: Full-time

About the Role

ETAP’s Cloud Division is expanding its AI/ML capabilities and is seeking a Data Science & Machine Learning Engineer to help design, build, and deploy intelligent systems at scale.

This hybrid role bridges data science and production engineering, focusing not only on building high-performing models but also on operationalizing them in real-world environments. You will work on high-impact initiatives across predictive modeling, graph machine learning, and generative AI, contributing directly to product innovation.

Key Responsibilities

• Design, develop, and deploy machine learning models for classification, regression, ranking, and recommendation systems
• Build end-to-end ML pipelines, from data ingestion and feature engineering to model deployment and monitoring
• Productionize models as scalable APIs using FastAPI, Docker, and cloud platforms (Azure ML)
• Implement robust validation, testing, and monitoring to ensure model performance and reliability in production
• Collaborate with data engineers and software teams to integrate ML solutions into production systems
• Monitor models for drift, retrain pipelines, and continuously improve performance

Required Qualifications

• Strong programming skills in Python, with expertise in Pandas, NumPy, and scikit-learn
• Experience building and deploying end-to-end ML systems in production environments
• Solid knowledge of SQL/NoSQL databases and data pipeline development
• Hands-on experience with XGBoost and/or LightGBM for structured data problems
• Experience with MLOps tools such as Git, Docker, MLflow/Weights & Biases, and Azure ML
• Strong understanding of model evaluation metrics and performance trade-offs

Preferred Qualifications

• Experience with deep learning frameworks (PyTorch or TensorFlow)
• Familiarity with model optimization and tuning (e.g., Optuna)
• Experience with Graph ML (PyTorch Geometric, DGL) or Generative AI (RAG, embeddings, LangChain, LlamaIndex)
• Knowledge of model serialization and deployment standards (ONNX)
• Experience working in cloud-native, distributed environments

What We’re Looking For

• A strong engineering mindset with the ability to take models from concept to production
• Curiosity and passion for applying cutting-edge AI/ML techniques
• A results-driven approach focused on delivering measurable business impact
• Strong collaboration and communication skills across technical and non-technical teams

What We Offer

• Competitive compensation aligned with the Mexican market
• Opportunity to work on cutting-edge AI/ML and cloud technologies
• A collaborative, innovative, and inclusive work environment
• Exposure to global teams and impactful projects
