Machine Learning Engineer (Remote)

About the role

BairesDev is seeking a senior Machine Learning Engineer to design and deliver end‑to‑end AI solutions, including NLP, large language models and agentic AI, for high‑impact products. You will work remotely with a global team of top‑tier technologists, turning business problems into reliable, cost‑controlled production systems.

Key responsibilities

• Co‑define AI solutions with product, engineering and data stakeholders, translating objectives into measurable metrics.
• Build data pipelines and feature‑engineering workflows using Python, PySpark and Databricks.
• Develop, train, evaluate and maintain traditional ML models and advanced NLP/LLM solutions (Transformers, embeddings, RAG, structured outputs).
• Design agentic workflows that connect LLMs with tools, APIs, retrieval systems and business rules, ensuring safety and observability.
• Package, deploy, monitor and retrain models on Databricks/MLflow and AWS, exposing FastAPI services for real‑time, batch and asynchronous workloads.

Required profile

• 7+ years of experience delivering end‑to‑end ML, NLP and LLM solutions from problem definition to production.
• Deep expertise in NLP, text intelligence and LLM techniques (tokenization, embeddings, semantic search, hallucination mitigation, etc.).
• Strong background in traditional ML models (classification, regression, ranking, forecasting, segmentation, anomaly detection, explainability).
• Proven MLOps experience with Databricks, MLflow and AWS, including CI/CD, monitoring, drift detection and cost optimization.
• Advanced proficiency in English.
