- Strong proficiency in Python and experience working with LLM APIs (OpenAI, Anthropic, Hugging Face) and vector databases such as Pinecone, Weaviate, or FAISS
- Solid understanding of model evaluation methodologies, including benchmarking, A/B testing, hallucination detection, and performance monitoring in production environments
- Experience with fine-tuning techniques such as SFT, RLHF, LoRA, and QLoRA, along with familiarity with parameter-efficient training approaches for domain-specific model customization
- Demonstrated ability to design and deploy production-grade AI systems with robust observability, logging, and monitoring capabilities ensuring reliability and performance at scale
Good-to-Have Skills
- Exposure to multi-modal AI capabilities including computer vision, document intelligence, or speech processing integrated within broader AI/ML pipelines
- Familiarity with low-code AI agent platforms (such as Microsoft Copilot Studio, Flowise, or similar) alongside the ability to build custom high-code agent implementations
- Experience working within cloud environments such as AWS, Azure, or GCP, leveraging managed AI/ML services for model training, deployment, and scaling
- Knowledge of responsible AI principles, including bias detection, fairness evaluation, and compliance considerations relevant to regulated industries such as financial services
- Familiarity with MLOps practices and tools such as MLflow, Weights & Biases, or similar platforms for experiment tracking, model versioning, and deployment automation
