About the role

Context windows, tool routing, and multi-agent orchestration are the core of what we build. If you've debugged a production incident caused by an agent calling a function with a malformed argument, you already understand why this role exists. You'll build the validation layer that catches schema violations, type mismatches, and hallucinated parameters before a tool call ever executes, across every agent our platform runs for customers.

Fully remote.

Responsibilities

  • Build schema validation for tool and function calls before execution
  • Catch type mismatches and hallucinated parameters at the routing layer
  • Drive adoption of validation tooling across internal agent teams
  • Own the fastapi validation service and its reliability SLAs

Requirements

  • Deep experience with llm tool-use and function calling patterns
  • Strong python and fastapi production experience
  • Familiarity with langchain or llamaindex agent frameworks
  • Track record owning high-reliability services in production

Benefits

  • Fully remote position
  • Meaningful equity package
  • Top-tier health, dental, and vision insurance
  • Annual research and conference budget
