• Apply rigorous scientific methodologies to experimentation, model evaluation, and performance optimization
• Develop scalable ML pipelines and production-grade systems in collaboration with Engineering teams
• Conduct prompt engineering, model alignment, evaluation, and performance benchmarking for GenAI applications
• Work closely with Product, Engineering, and Business stakeholders to translate ambiguous requirements into data-driven AI solutions
• Instrument and monitor LLM applications in production using observability tools, tracking cost, latency, quality, and drift
• Contribute to model governance, responsible AI practices, and performance monitoring in production environments
• Stay current with advancements in Generative AI, LLM research, and applied machine learning, incorporating relevant innovations into company solutions

• Master's or PhD in Computer Science, Data Science, Statistics, Mathematics, Engineering, or a related quantitative field
• Minimum 5 years of hands-on industry experience in AI engineering, machine learning, data science, or applied AI roles
• Strong experience with Generative AI frameworks and Large Language Models (e.g., transformer architectures, fine-tuning, RAG systems)
• Proficiency in Python and modern ML/AI libraries such as PyTorch, TensorFlow, Hugging Face, or equivalent ecosystems
• Solid understanding of statistical modeling, experimentation, and model evaluation methodologies
• Experience building and deploying ML models into production environments
• Familiarity with data engineering workflows and cloud-based ML platforms (AWS, GCP, or Azure)
• Strong problem-solving skills with the ability to work independently on complex and ambiguous problem statements
• Excellent communication skills with the ability to present technical insights clearly to cross-functional stakeholders

• Experience implementing Retrieval-Augmented Generation (RAG), vector databases, and embedding-based search systems
• Hands-on experience with LLM observability platforms (e.g., Langfuse, LangSmith, Arize Phoenix, Weights & Biases) for tracing, cost tracking, and quality monitoring in production
• Experience with LLM evaluation frameworks (e.g., RAGAS, DeepEval) and evaluation patterns such as LLM-as-judge and automated regression testing
• Practical experience deploying LLM applications with guardrails, prompt versioning, hallucination detection, and model drift monitoring
• Exposure to distributed training, model optimization, and scalable inference architectures
• Knowledge of MLOps practices, CI/CD for ML (Travis CI, Jenkins), and model lifecycle management
• Prior experience applying AI solutions in industrial or asset-intensive environments
• Experience working in fast-paced startup or product-driven environments
• Industry experience in one or more of the following domains: Mining, Oil & Gas, Aerospace, Supply Chain, Logistics, or Renewable Energy
