Responsibilities
Architect and lead development of large-scale evaluation platforms for LLMs and agents, enabling automated, reproducible, and extensible assessment of accuracy, reliability, safety, and performance across diverse domains
Define organizational standards and metrics for LLM/agent evaluation, covering hallucination detection, factuality, bias, robustness, interpretability, and alignment drift
Build platform components and APIs that allow product teams to integrate evaluation seamlessly into training, fine-tuning, deployment, and continuous monitoring workflows
Design automated pipelines and benchmarks for adversarial testing, red-teaming, and stress testing of LLMs and retrieval-augmented generation (RAG) systems
Lead initiatives in multi-dimensional evaluation, including safety (toxicity, bias, harmful outputs), grounding (retrieval correctness, source attribution), and agent behaviors (tool use, planning, trustworthiness)
Collaborate with cross-functional stakeholders (safety, product, research, infrastructure) to translate abstract evaluation goals into measurable, system-level frameworks
Advance interpretability and observability, developing tools that allow teams to understand, debug, and explain LLM behaviors in production
Mentor engineers and establish best practices, driving adoption of evaluation-driven development across the organization
Influence technical roadmaps and industry direction, representing the team’s evaluation-first approach in external forums and publications
Qualification
Required
5+ years of ML engineering experience, with 3+ years focused on large-scale evaluation of transformer-based LLMs and/or agentic systems
Proven experience building evaluation platforms or frameworks that operate across training, deployment, and post-deployment contexts
Deep expertise in designing and implementing LLM evaluation metrics (factuality, hallucination detection, grounding, toxicity, robustness)
Strong background in scalable platform engineering, including APIs, pipelines, and integrations used by multiple product teams
Demonstrated ability to bridge research and engineering, operationalizing safety and alignment techniques into production evaluation systems
Proficiency in Python, PyTorch, Hugging Face, and modern ML ops/deployment environments
Track record of technical leadership, including mentoring, architecture design, and defining org-wide practices
Preferred
Experience with multi-agent evaluation frameworks and graph-based metrics for agent interactions
Background in retrieval-augmented generation (RAG) evaluation (retrieval precision/recall, grounding, attribution)
Contributions to AI safety or evaluation research in industry or academia
Familiarity with adversarial testing methodologies and automated red-teaming
Knowledge of interpretability and transparency methods for LLMs
Advanced degree in ML/CS or related field with focus on evaluation, safety, or interpretability
