Role & Expectations
As an Agent Harness Engineer, you will design and implement the agent control and execution infrastructure, leveraging your AI/ML knowledge.
- Design and implement the execution engine (Graph Runtime / State Machine) with deep understanding of LLM / AI agent operating principles
- Own AI-specific system design including model routing, context management, and memory infrastructure (long-term memory, working memory)
- Design and develop the Agent SDK used by 120 in-house engineers
- Build the guardrail / policy execution engine to safely control agent behavior
- Collaborate with Research Engineers to integrate the latest research outcomes into the production infrastructure
Job Description
- Agent Harness design & implementation
- Design and implement the agent execution engine (Graph Runtime / State Machine)
- Design and develop the Agent SDK — the interface for in-house engineers to build agents
- Implement session management, checkpoint, and recovery mechanisms
- Build the guardrail / policy execution engine — a rule execution infrastructure that controls agent behavior
- AI/ML System Integration
- Model routing — optimal routing of inference requests across multiple LLM providers and model types
- Design context management and memory infrastructure (long-term memory, working memory, RAG integration)
- Optimize inference pipelines (latency reduction, cost efficiency, caching strategies)
- Integrate latest research findings into the production infrastructure in collaboration with Research Engineers
- Orchestration & performance
- Develop workflow orchestration and queuing systems
- Cost/performance optimization (autoscaling, caching, batch processing)
- Inference request routing and load balancing
- Reliability & Operations
- Maintain platform uptime of ≥99.9%
- Incident response and post-mortems
- Design data access and permission management infrastructure
