What You'll Do

• Build, test, and deploy production-grade AI solutions using generative AI techniques, including LLMs, RAG, fine-tuning, prompt optimization, and agentic workflows
• Help redesign how business development activity is modeled, processed, controlled, and reported across the firm
• Shape AI-first systems architecture across multiple platforms supporting business development and incentive workflows
• Design and implement evaluation frameworks to measure solution quality, robustness, reliability, and business impact
• Partner closely with product managers, data engineers, and business stakeholders to translate business needs into scalable, production-ready solutions
• Contribute to real-time and batch data pipelines, including monitoring, logging, metrics, guardrails, and human-in-the-loop review processes
• Work across regions and departments to understand business workflows, contractual documents, and unstructured data, and apply those insights to effective AI solution design
• Perform data cleansing, data engineering, and pipeline development to make AI solutions reliable, scalable, and production-ready

What You Bring

• 5–6 years of data engineering experience, including 1–2 years of hands-on AI experience
• Experience building production-grade generative AI solutions at enterprise scale, including Model Context Protocols (MCPs), agent architectures, and Retrieval-Augmented Generation (RAG); exposure to GraphRAG is a plus
• Strong hands-on experience with Python, AWS, Bedrock, LLMs, RAG, and agentic AI
• Strong working experience in Linux environments and with AI coding tools such as Cursor, Copilot, and Claude
• Familiarity with agent orchestration frameworks such as LangGraph, Pydantic, or similar tools is highly desirable
• Experience with workflow orchestration tools such as Airflow or Temporal for running agentic flows and batch jobs
• Strong understanding of LLMs, RAG, prompt engineering, conversational AI platforms, and modern AI-powered user experiences
• Bachelor’s degree in Computer Science or a related field
• If you want, I can also tighten this further into a more external-facing, candidate-marketing version while keeping the same facts.
