Meet the Team

The Information Technology department is core to the health and growth of Millennium’s business. The firm’s active, multi-manager model demands flexible, scalable technology and advanced proprietary systems, including the development of the next generation of analytical and trading capabilities. The Fixed Income Rapid Application Development (RAD) team is a specialized group of engineers, quants, and data scientists that delivers tactical, production-grade application and AI solutions for Fixed Income portfolio managers, traders, risk, and operations teams.

• Design and build data visualizations and web UIs (React/TypeScript) that surface data trends and streamline PM/trading/risk workflows.
• Develop and integrate AI/LLM-powered capabilities into team applications, e.g., Retrieval-Augmented Generation (RAG), chat-data ingestion pipelines, MCP (Model Context Protocol) servers/tools, building and using AI coding agent automation (Claude Code/Codex/Cursor)
• Partner with Fixed Income Management, Execution, and Risk teams to capture requirements, monitor delivery, and manage expectations for both traditional analytics tools and newer AI-driven applications.
• Maintain, support, and continuously improve deployed capabilities as new requirements arise
• Fit into FI-RAD\'s fast-moving culture, judged on the ability to deliver timely, production-quality solutions directly to PMs and risk/trading desks.

What You Bring

• Bachelor’s degree in Computer Science or a related field
• 5+ years of development experience in a production environment, ideally with Python using data science stack libraries
• Experience in financial markets, including areas such as rates, FX, credit, or commodities using mathematics, modeling, and/or statistics
• Experience with AI/LLM tools for development and/or AI solutions such as Agent Tools, Skills, MCPs
• Full stack experience with React+Typescript/Deno and cloud technologies (Kubernetes EKS/ArgoCD)
• Strong communication skills and the ability to work independently in a fast-paced setting
• High attention to detail, strong organization, and a clear sense of ownership and accountability for your work
