WHO YOU ARE You are a passionate Python and AI/ML Engineer minimum 4 years of hands-on experience building intelligent systems. You thrive in fast-paced environments, love solving complex problems with data and algorithms, and take pride in delivering AI solutions that create real business impact. You have experience with cutting-edge Generative AI, scalable ML pipelines, and production-grade systems and you're energized by working at the frontier of what AI can do. WHAT YOU'LL DO

Design, develop, and deploy machine learning models and Generative AI solutions — including classification, clustering, summarization, search & ranking, and information extraction. Own end-to-end ML pipelines — from data ingestion and preprocessing through model training, deployment, and production monitoring. Collaborate with cross-functional teams to translate business requirements into AI-driven features — applying NLP, outlier detection, and deep learning techniques where applicable. Build robust, scalable, and well-documented Python-based RESTful APIs to expose ML models and AI services in production environments. Optimize database interactions and ensure efficient data storage and retrieval for AI applications across SQL and NoSQL systems. Stay current with the latest advances in AI/ML — integrating emerging approaches such as RAG pipelines, LLM fine-tuning, and vector search into live products.
