Responsibilities

  • Own the evaluation roadmap and strategy for agentic AI quality from architecture through production operation.
  • Design layered evaluation systems using deterministic checks, model-based evaluation, and calibrated human expert review.
  • Build and calibrate multi-model LLM-as-judge panels and validate them against human experts.
  • Operate human-in-the-loop evaluation workflows, converting annotations into training signals for automated judges.
  • Score live production traffic, detect regressions and drift, and turn production traces into offline test cases.
  • Lead simulation, synthetic data generation, adversarial testing, and evaluation of multi-step agent behavior.
  • Connect evaluation failures to clustered issues, candidate fixes, and shadow or A/B validation.
  • Maintain experiment snapshots, dataset versioning, coverage reporting, and cost tracking for trustworthy results.
  • Drive shared standards, data contracts, and judge criteria across partner teams through influence rather than reporting authority.
  • Mentor engineers, establish evaluation engineering standards, and represent the domain to senior leadership.

Requirements

  • BA/BS in Computer Science, Machine Learning, or a related quantitative field with 8+ years of relevant experience, or an MS with 6+ years, or a PhD with 3+ years.
  • Experience taking machine learning or LLM-based systems into production and owning them operationally.
  • Experience with Python and modern deep learning frameworks such as PyTorch or TensorFlow.
  • Experience designing evaluation, measurement, or quality systems for ML or LLM products, including datasets, metrics, judges, benchmarks, or regression suites.
  • Experience setting technical direction across multiple teams through influence rather than reporting lines.
  • Preferred experience designing and calibrating LLM-as-judge systems against human experts, including inter-annotator agreement and judge drift.
  • Preferred experience evaluating agentic systems, including multi-step reasoning, tool selection, trajectory quality, and root-cause correctness.
  • Preferred experience with asynchronous production scoring, drift detection, alerting, simulation, synthetic environments, CI/CD evaluation, cost-aware inference, or networking and observability domains.
  • Publications at top ML venues, open-source contributions, or public technical writing in the evaluation space are preferred.

Benefits

  • Medical, dental, and vision insurance, a 401(k) with Cisco matching contributions, paid parental leave, disability coverage, and basic life insurance.
  • Paid holidays, birthday leave, year-end shutdown, personal wellness days, sick time, vacation or flexible time off depending on employee classification, and optional paid volunteer days.
  • Employees may be eligible for Cisco restricted stock units and annual bonuses subject to company policies.
  • The posting applies to U.S. and/or Canada locations, with location-specific salary ranges and benefits eligibility governed by Cisco plans and policies.
