What you'll do

  • Design and implement evaluation frameworks, benchmarks, and datasets for LLM-powered agents and complex AI workflows.
  • Identify, analyze, and prioritize model, agent, and workflow failures in real-world production environments.
  • Run rapid experiments to validate hypotheses, measure performance, and improve agent reliability and effectiveness.
  • Partner with enterprise customers and researchers to evaluate, deploy, and optimize AI systems across production workflows.
  • Develop high-quality training and evaluation data, task specifications, and feedback mechanisms to improve system performance.
  • Build Python-based evaluation pipelines, experimentation tools, and lightweight research infrastructure.
  • Collaborate with researchers, domain experts, and customer stakeholders to define evaluation strategies and optimization roadmaps.
  • Contribute to technical reports, benchmarks, and research insights that inform future system improvements.

What we're looking for

  • Strong background in applied AI research, research engineering, machine learning, or LLM-based systems.
  • Hands-on experience designing and implementing evaluations for AI agents, including tool use, multi-step workflows, and task completion.
  • Strong Python programming skills and experience building evaluation pipelines, experimental tooling, or ML infrastructure.
  • Experience developing benchmarks, datasets, evaluation metrics, and experimental methodologies for AI systems.
  • Ability to analyze agent failures, identify root causes, and translate findings into measurable performance improvements.
  • Understanding of LLM behavior, agentic architectures, and common challenges in reliability, robustness, and generalization.
  • Ability to translate ambiguous real-world problems into structured experiments and actionable technical solutions.
  • Strong collaboration and communication skills, with the ability to work across research, engineering, and customer teams.

Nice to have

  • Experience evaluating or optimizing AI agents in production or enterprise environments.
  • Familiarity with reinforcement learning, reward modeling, or post-training techniques.
  • Experience building research infrastructure, evaluation tooling, or automated experimentation frameworks.
  • Prior experience at a frontier AI lab or in an applied AI research environment.
  • Contributions to research publications, open-source benchmarks, or AI evaluation frameworks.
  • Experience collaborating directly with enterprise customers or technical stakeholders.
