About the role

Role focused on building benchmarks, datasets, tooling, and evaluation loops to measure and improve model quality for AI agents in risk investigations, fraud review, and identity reviews at Variance (SF-based). Centered in research, product, and engineering to drive domain-specific evaluations and robust system quality.

Responsibilities

  • Build proprietary benchmarks and datasets to evaluate models and model systems on fraud, identity, and risk workflows
  • Design and run offline and online evals that measure model performance on real customer tasks, not just abstract benchmarks
  • Define quality metrics for judgment systems, including precision, calibration, consistency, abstention, and failure handling
  • Study where models and agents break, and turn those failures into better evals, better datasets, and better training loops
  • Build reusable evaluation tools and quality building blocks that can be used across different product surfaces and workflows
  • Partner closely with research, engineering, product, and design to improve system quality through rigorous experimentation
  • Help create a strong culture of scientific experimentation, clear measurement, and continuous iteration
  • Push the boundary of how AI systems are evaluated in regulated, adversarial, and high-consequence environments

Qualifications

  • Experience training, evaluating, or improving modern ML systems
  • Strong programming skills and comfort working in research-heavy codebases
  • Experience building benchmarks, datasets, evaluation pipelines, or quality systems
  • Familiarity with LLMs, agent systems, retrieval, post-training, or adjacent areas
  • Ability to design clean experiments and draw reliable conclusions from noisy results
  • Strong engineering judgment and a bias toward building
  • Interest in fraud, risk, trust and safety, compliance, or other regulated and adversarial domains
