Responsibilities

  • Define and evolve technical approaches for evaluating and improving open agent harnesses across frameworks, models, and benchmark environments.
  • Build and operate scalable, reproducible evaluation systems covering CI, scheduled compute, sandboxed execution, artifact provenance, trace capture, and analysis.
  • Diagnose agent failures using traces, logs, tool results, and benchmark artifacts across harness, evaluator, environment, inference, and model causes.
  • Design controlled experiments and promotion criteria to distinguish genuine improvements from noise, benchmark artifacts, and model-specific gains.
  • Ship harness and runtime improvements, including open-source contributions, detectors, regression tests, and documentation.
  • Partner with Relay, Hermes, model, infrastructure, and research teams to create reusable runtime, trace, and evaluation capabilities.

  • Expert Python skills and working proficiency in Rust, Go, C++, or TypeScript, including debugging across language and process boundaries.
  • Experience building or extending LLM agents, coding agents, tool-use loops, model-provider integrations, developer tools, or evaluation infrastructure.
  • Understanding of asynchronous execution, subprocesses, containers, sandboxing, callbacks, retries, networking, and distributed compute.
  • Experience with reproducible experiments, benchmark methodology, performance investigations, regression gates, or reliability analysis under nondeterministic conditions.
  • Record of shipping and maintaining open-source or developer-facing software with testing, API development, documentation, and code reviews.
  • Preferred experience includes open-source contributions, published research or technical writing, public agent benchmarks such as SWE-bench, Terminal-Bench, or AgentBench, and trace-analysis or observability systems such as OpenTelemetry and OpenInference.
