Senior Agent Systems Engineer

Senior Agentic AI Engineer

A frontier AI company is building systems that can act in the physical world, experimenting, engineering, and executing multi‑step processes with real‑world constraints. Backed by major research funding and operating at the edge of physical‑AI innovation, they’re creating capabilities that don’t exist anywhere else. Join to work from first principles, own high‑impact systems end‑to‑end, and help define how agentic AI will operate complex workflows in the real world.

• Build agent systems that plan, execute, and recover across intricate engineering workflows
• Shape foundational behaviour patterns for next‑gen LLM tool‑use
• Join early enough to influence architecture, culture, and performance standards
• Work on problems that sit far beyond typical “LLM app” engineering

• Develop planners, state machines, and tool‑calling flows using frameworks like Lang Graph
• Create schemas, action definitions, and cross‑tool interfaces for reliable, traceable execution
• Build error‑handling, timeouts, retries, rollbacks, and replay mechanisms
• Partner with ML, infra, and systems teams to integrate agents into real engineering tool chains

• Strong experience with agent systems, structured tool calling, or orchestration frameworks
• Deep intuition for schemas, deterministic execution, and multi‑step workflow design
• Ability to model failure modes, edge cases, and safe interactions in complex systems
• Comfort working across AI, systems engineering, and specialised domain tools in a high‑precision environment
