Senior AI Agent Infrastructure Engineer
Nov 2025 - Ongoing6 months
Project Overview

Developed core infrastructure for an AI agent platform supporting financial forecasting and research workflows. Built the organizational knowledge retrieval layer that enabled AI agents to access and reason over information from repositories, documentation, collaboration tools, and other internal data sources.

Responsibilities:
  • Owned the end-to-end implementation of an organizational context layer for AI agents supporting financial forecasting workflows;
  • Designed and implemented ETL pipelines that ingested repositories, commits, configuration files, Slack, Notion, and Google Drive content;
  • Built agent-facing retrieval APIs for semantic search, symbol search, regex search, file discovery, and file retrieval;
  • Implemented an OCL agent that accepted tasks from other agents, queried the organizational context layer, and returned grounded answers from indexed company knowledge;
  • Created evals to measure OCL data quality, retrieval coverage, and answer usefulness for agent workflows;
  • Integrated PostgreSQL/Drizzle metadata storage, ChromaDB vector search, and S3-compatible artifact storage for indexed context;
  • Implemented webhook-based source synchronization, pipeline orchestration, job status tracking, cancellation, and recovery flows;
  • Developed admin and API surfaces for managing sources, source groups, users, connections, pipelines, and webhook events;
  • Containerized Python ETL services for code, config, commit, and document ingestion;
