About Grafton Sciences
We’re building AI systems with general physical ability — the capacity to experiment, engineer, or manufacture anything. We believe achieving this is a key step towards building superintelligence. With deep technical roots and real-world progress at scale (e.g., a $42M NIH project), we’re pushing the frontier of physical AI. Joining us means inventing from first principles, owning real systems end-to-end, and helping build a capability the world has never had before.
About the Role
We’re seeking a Agent Systems Engineer to design and implement the planning, orchestration, and tool-use behaviors that enable LLMs to reliably operate complex engineering workflows. You’ll build LangGraph planners, deterministic execution flows, action schemas, recovery strategies, and cross-tool interfaces that allow agents to reason over multi-step tasks with safety and reproducibility. This role is for someone who thrives at the intersection of language models, structured schemas, tool interfaces, and real system constraints.
Responsibilities
• Build agent planners, tool-call flows, and state machines using LangGraph or similar frameworks.
• Design schemas, action adapters, and cross-tool interfaces that enable deterministic, traceable LLM tool use.
• Implement error handling, timeout strategies, retries, rollbacks, and replay mechanisms for robust agent behavior.
• Collaborate closely with systems architecture, data infrastructure, and ML teams to integrate agents into real engineering toolchains.
Qualifications
• Strong experience building agent systems, LLM tool-calling pipelines, or structured orchestration frameworks.
• Deep intuition for schemas, action abstractions, reproducibility, and deterministic execution of multi-step workflows.
• Ability to reason about system-level failure modes, edge cases, and safe tool interaction in complex environments.
• Comfortable working across AI, systems engineering, and domain-tooling interfaces in a fast-moving, high-precision setting.
Above all, we look for candidates who can demonstrate world-class excellence.
