Role description
π Now Hiring: Principal Generative AI Scientist (Financial Services Domain)
π Location: Fulltime on-site Monday to Friday in Mclean
π Employment Type: Contract / Full-time
Are you ready to push the boundaries of Generative AI in a highly regulated and data-rich environment? We're seeking a Principal Gen AI Scientist to lead the development of innovative AI Agents, Agentic Workflows, and GenAI Applications that drive real business impact in the financial services industry.
This is a hands-on role where you'll work at the cutting edge of AI β applying advanced techniques in LLMs, RAG, Graph RAG, multimodal AI, evaluation frameworks, and AWS cloud solutions β to build scalable, enterprise-grade solutions.
π§ What You'll Do
β’ Architect, design, and implement AI Agents and Agentic Workflows for real-world, high-value use cases.
β’ Build and optimize lightweight LLMs; evaluate and integrate models like Claude, Azure OpenAI, and open-source alternatives.
β’ Develop Retrieval Augmented Generation (RAG) systems and Graph RAG solutions using vector databases.
β’ Curate enterprise knowledge bases via AWS Bedrock, Elastic, and other tools.
β’ Drive integration of MCP (Model Context Protocol) and A2A (Agent-to-Agent) communication into AI workflows.
β’ Collaborate with cross-functional teams β including product managers, designers, full-stack engineers, and data engineers β to create full-stack GenAI products.
β’ Deploy production-grade GenAI solutions with evaluation frameworks, guardrails, and bias mitigation.
β’ Build data pipelines to extract, chunk, anonymize, and enrich data from unstructured formats like PDFs, video, and audio.
β’ Lead multimodal orchestration for AI using frameworks such as Apache Spark, PySpark, and MLFlow/Kubeflow on AWS EKS.
β’ Map media content to vector representations and integrate with platforms like AWS Knowledge Base, Elastic, and MongoDB Atlas.
β
What Weβre Looking For
β’ MS/PhD in AI, Machine Learning, Data Science, or a related field.
β’ 10+ years of AI/ML experience, with 3+ years in applied GenAI/LLM solutions.
β’ Proven expertise in:
β’ Prompt engineering
β’ LLM fine-tuning and deployment
β’ RAG/Graph RAG architectures
β’ Multimodal model development
β’ Vector databases and embeddings
β’ Cloud-native ML pipelines (AWS, SageMaker, Bedrock, EKS)
β’ Strong programming skills: Python, Jupyter, Transformers, LangChain, etc.
β’ Solid understanding of GenAI system design patterns, evaluation frameworks, and MLOps best practices.
β’ Ability to operate in a fast-paced, agile, and collaborative environment.
β’ Must provide a GitHub or public code repository demonstrating recent GenAI work.
β Preferred Qualifications
β’ Published research or patents in GenAI/LLM/ML domains.
β’ Experience with AI governance, bias mitigation, and secure GenAI deployments.
β’ Built and deployed full-stack GenAI applications using MCP, A2A, and Graph RAG in production.
β’ Familiarity with CI/CD workflows and scalable inference APIs.
π Important:
Candidates must demonstrate hands-on GenAI experience β including prompt design, model deployment, building agents, and handling unstructured data at scale.
GitHub repositories or code samples are required as part of the application.
Interested in making a real impact with GenAI? Apply now and be part of a transformative journey in the financial services industry.
