Job Description

As a Director of AI/ML within the Commercial and Investment Bank, you will set the vision and lead the enterprise portfolio for agentic AI that automates and optimizes complex business workflows  will guide cross-functional teams and strategic partners to define reference architectures and delivery roadmaps for multi-agent systems—leveraging LLMs, retrieval-augmented generation, and modern agent frameworks—while instituting governance, safety, and reliability standards and tracking measurable business outcomes.

Responsibilities
  • Architect, develop, and product ionize autonomous and assistive AI agents to streamline and enhance operations.
  • Design multi-agent systems, including role definition, tool integration, planning, memory, and workflow orchestration using Lang Chain, CrewAI, Auto Gen, ADK and Lang Graph.
  • Implement Retrieval-Augmented Generation (RAG) pipelines and semantic search using vector databases such as Pinecone and Chroma, including indexing, retrieval policies, and evaluation.
  • Build and integrate agent tools (MCP) and APIs to connect agents with external services, databases, and internal systems, ensuring robust output parsing, error handling, and retries.
  • Design and implement robust evaluation frameworks to systematically assess and measure the performance of AI agents across key operational metrics.
  • Practice advanced prompt and context engineering (e.g., Chain-of-Thought, ReAct, function calling/tool-use prompts), implement output validation and guardrails to reduce hallucinations.
  • Deploy scalable AI services to cloud infrastructure, ensuring monitoring and observability for agent performance.
  • Design microservices-based architectures and orchestrate multi-step workflows; instrument agents for tracing, metrics, and feedback loops to continuously improve reliability and utility.
  • Partner with stakeholders to define requirements, design intuitive human-AI interfaces (voice, chat), and deliver measurable business impact.
  • Analyze data to inform agent capabilities, optimize retrieval, and drive data-driven decision-making; and performance evaluations.
  • Mentor and guide team members on agent frameworks, LLM usage, safety, and best practices.
Required qualifications

  • Significant proven experience building and deploying AI applications in large scale production environments.
  • Experience managing data science teams and coaching team members.
  • Proficiency in Python and ML frameworks (PyTorch, Tensor Flow, scikit-learn).
  • Hands-on experience with agentic frameworks (Lang Chain, CrewAI, Auto Gen, Lang Graph, ADK).
  • Experience with generative models (transformers, GANs/VAEs; diffusion models a plus).
  • Strong understanding of data preprocessing, feature engineering, and evaluation techniques.
  • Familiarity with cloud platforms (AWS, Azure, GCP) and containerization (Docker, Kubernetes).
  • Strong communication skills for both technical and non-technical audiences.
Preferred qualifications
  • Experience fine-tuning small language models (SLMs) with LoRA, QLoRA, DoRA; quantization and distillation a plus.
  • Familiarity with prompt optimization frameworks (Auto Prompt, DSPy) and building evaluation suites.
  • Experience with distributed computing, data sharding, and performance optimization.
  • Hands-on with AWS AI deployment services (Sage Maker, Bedrock) and workflow orchestration.
  • Demonstrated experience in financial services, particularly investment banking operations.
