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, LLM and agentic systems, for high‑impact products. You will work remotely with a global team, turning business problems into reliable, production‑grade models.

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, including safety checks and observability.
• Package, deploy, monitor and retrain models on Databricks/MLflow and AWS, exposing FastAPI services for real‑time, batch and async workloads.

Required profile

• 7+ years delivering end‑to‑end ML, NLP, LLM and agentic AI solutions.
• Deep expertise in NLP, text intelligence and LLM techniques (tokenization, embeddings, semantic search, RAG, hallucination mitigation).
• Strong background in traditional ML (classification, regression, ranking, forecasting, segmentation, anomaly detection, explainability).
• Proven experience designing multi‑step agentic AI workflows with memory management and human‑in‑the‑loop review.
• Extensive MLOps experience on Databricks/MLflow and AWS, covering CI/CD, monitoring, drift detection and cost optimization.
• Advanced proficiency in English.
