Machine Learning Engineer (Remote)

About the role

Join BairesDev as a Machine Learning Engineer and lead the design, development, and production deployment of cutting‑edge ML, NLP, LLM, and agentic AI solutions. You will work remotely with a global team, turning complex business problems into reliable, high‑performance AI products.

Key responsibilities

• Co‑define AI solutions with product, engineering, and data stakeholders, translating business goals into measurable metrics.
• Build data pipelines and feature‑engineering workflows using Python, PySpark, and Databricks for training, evaluation, batch scoring, and online inference.
• Develop, train, evaluate, and maintain traditional ML models and advanced NLP/LLM solutions, including Transformers, embeddings, RAG, and structured outputs.
• Design agentic workflows that connect LLMs with tools, APIs, retrieval systems, and business rules, ensuring safety, observability, and human‑in‑the‑loop review.
• 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 end‑to‑end experience delivering ML, NLP, LLM, and agentic AI solutions.
• Deep expertise in NLP, text intelligence, and LLM techniques such as tokenization, embeddings, semantic search, RAG, and hallucination mitigation.
• Strong background in traditional ML models (classification, regression, ranking, forecasting, segmentation, anomaly detection, explainability).
• Proven production MLOps experience with Databricks, MLflow, and AWS, including CI/CD, monitoring, drift detection, and cost optimization.
• Advanced proficiency in English.
