Software Engineer – Agent Harness

Responsibilities

• Design and build the agent loop: planning, tool invocation, observation handling, retries, termination
• Implement tool integrations — file I/O, terminal / shell execution, web, MCP servers, message apps
• Build context management: what goes in the window, when to summarize, how to use long / cross-session memory
• Implement scheduling and automatic / background task execution
• Keep the harness model-agnostic so local and cloud models are swappable behind one abstraction
• Design agent security mechanisms through different approaches
• Make the loop observable, debuggable: tracing, replay, and reproducible agent sessions

• 5+ years software development background
