About the Role
Quant is the team responsible for our multi-modal intelligence agent, building software to surface hidden patterns across disparate data sources and generate predictive outcomes. As part of this team, you'll design and build agent systems, tool integrations, and evaluation pipelines, owning the orchestration layer that converts complex operator requirements into secure, reliable, and measurable AI capabilities.
Responsibilities
- Build asynchronous Python/TypeScript services with FastAPI, Pydantic, and asyncio.
- Develop agent orchestration, subagent delegation, tool calling, and structured outputs.
- Design MCP tools and AG-UI/SSE integrations.
- Improve prompt, context, memory, and token-management strategies.
- Build safeguards against prompt injection, data leakage, and unsafe tool use.
- Create behavioral evals and regression datasets using Langfuse.
- Trace model calls and tool execution with Langfuse, Sentry, and OpenTelemetry.
- Diagnose failures spanning model behavior, tools, data sources, and distributed services.
Requirements
- Strong production Python and asynchronous programming experience.
- Experience building LLM applications with tool use and multi-step reasoning.
- Knowledge of structured output validation and non-deterministic system testing.
- Practical understanding of prompt injection and sensitive-data risks.
- Ability to evaluate AI behavior empirically rather than relying on demonstrations.
