Senior Agent Systems Engineer

san francisco, ca • Posted 1 weeks ago
Onsite Full Time Engineering

What You’ll Do

  • Build agent planners, tool-call flows, and structured state machines using LangGraph or similar frameworks
  • Design schemas, action adapters, and cross-tool interfaces that enable deterministic, traceable LLM tool execution
  • Implement robust execution logic: retries, rollbacks, timeouts, checkpointing, and replay mechanisms
  • Design agent workflows with clear validation, stopping criteria, and failure handling

What We’re Looking For

  • Strong experience building agent systems, LLM tool-calling pipelines, or orchestration frameworks
  • Deep intuition for schemas, action abstractions, state representation, and reproducibility
  • Ability to reason rigorously about system-level failure modes, edge cases, and safe tool interaction

Why This Role

  • Build agent systems that operate reliably in production, not just prototypes
  • Work on complex, high-impact engineering workflows with real constraints
  • High ownership and influence in a deeply technical environment

Apply if you want to build agent systems that actually work - deterministically, safely, and at scale.
