Build and evolve open agent harnesses that make AI agents safer, faster, and easier to trust. You’ll design scalable, reproducible evaluation systems across CI, sandboxed execution, trace capture, and analysis; diagnose failures from logs and artifacts; and ship harness/runtime improvements including upstream open-source contributions and regression tests. You’ll collaborate with Relay, Hermes, model, infrastructure, and research teams to turn recurring optimization needs into reusable capabilities.

Key Responsibilities

  • •Define and evolve the technical approach for evaluating and improving open agent harnesses across frameworks, models, and benchmark environments.
  • •Build and operate scalable, reproducible evaluation systems across CI, scheduled compute, sandboxed execution, artifact provenance, trace capture, and analysis.
  • •Diagnose agent failures from traces, logs, tool results, and benchmark artifacts to separate harness, evaluator, environment, inference, and model causes.
  • •Design controlled experiments and promotion criteria to distinguish true harness improvements from noise, benchmark artifacts, or model-specific gains.
  • •Ship harness and runtime improvements, including upstream open-source contributions, detectors, regression tests, and maintainable documentation.
