Agent Systems Engineer

Responsibilities

• Design and implement long-running, harness-based multi-agent architectures - covering topologies, orchestration, memory management, tool registries, and execution environments.
• Develop behavioral and persona models with goal-directed simulations, including evaluation frameworks, prompt schemas, and automated or human-in-the-loop feedback mechanisms to measure fidelity and surface failure modes.
• Build signal and insight systems that translate agent outputs into actionable product decisions, enabling data-driven iteration across research, product, and engineering teams.
• Ensure production reliability through comprehensive tracing, cost monitoring, failure detection, and robust fallback strategies.
• Collaborate cross-functionally with distributed systems, machine intelligence, and product teams to deliver measurable, scalable agent capabilities.

Requirements

• 5+ years of hands-on experience designing and implementing production-grade distributed systems and agent-based architectures
• Strong proficiency in Python, with substantial async programming experience.
• Demonstrated experience building production ML systems, including tracing, cost monitoring, failure detection, and robust fallbacks.
• Hands-on experience with containerisation and orchestration (Docker, Kubernetes) for large-scale agent infrastructures.
• Experience designing behavioral models, goal-directed simulations, evaluation frameworks, prompt schemas, and human-in-the-loop feedback mechanisms.
• Proven ability to translate agent outputs into actionable product decisions; experience building signal and insight systems.
• Strong cross-functional communication and collaboration skills across technology, research, and product.
