• Develop prompt engineering, optimization, and safety techniques for agentic LLM interactions.
• Integrate memory, evidence packs, and explainability modules into agentic pipelines.
• Work with multiple LLM ecosystems, including:
• OpenAI GPT (GPT-4, GPT-4o, fine-tuned GPTs)
• Anthropic Claude (Claude 2/3 for reasoning and safety-aligned workflows)
• Google Gemini (multimodal reasoning, advanced RAG integration)
• Meta LLaMA (fine-tuned/custom models for domain-specific tasks)
• Data & Infrastructure
• Collaborate with Data Engineering to build and maintain real-time and batch data pipelines supporting ML/LLM workloads.
• Conduct feature engineering, preprocessing, and embedding generation for structured and unstructured data.
• Implement model monitoring, drift detection, and retraining pipelines.
• Utilize cloud ML platforms such as AWS SageMaker and Databricks ML for experimentation and scaling.
• Research & Applied Innovation
• Explore and evaluate emerging LLM/SLM architectures and agent orchestration patterns.
• Experiment with generative AI and multimodal models (text, images, structured financial data).
• Collaborate with R&D to prototype autonomous resolution agents, anomaly detection models, and reasoning engines.
• Translate research prototypes into production-ready components.
• Collaboration & Delivery
• Work cross-functionally with R&D, Data Science, Product, and Engineering teams to deliver AI-driven business features.
• Participate in architecture discussions, design reviews, and model evaluations.
• Document experiments, processes, and results for effective knowledge sharing.
• Mentor junior engineers and contribute to best practices in ML engineering.
