Title and Summary
Manager, AI Engineering (Tester )
Mastercard's Business & Market Insights (B&MI) group delivers unparalleled data-driven intelligence and frontier AI solutions that help organizations make smarter, faster, and more impactful decisions. We are currently looking for a AI Tester for the Operational Intelligence Program within B&MI. This is a highly specialized, hands-on AI testing leadership position dedicated to ensuring our Generative AI, LLM, and agentic systems are accurate, safe, reliable, and enterprise-ready. This role will lead AI quality engineering efforts - defining evaluation frameworks, red-teaming strategies, and LLMOps quality gates - while fostering a culture of rigorous, first-class AI testing across the program.
Roles and Responsibilities:
• Design and own end-to-end LLM evaluation frameworks - including automated prompt regression pipelines, output scoring, semantic benchmarking, and hallucination detection across model versions and prompt variations.
• Build comprehensive test suites for agentic AI systems - validating tool selection, inter-agent coordination, task decomposition, goal completion, and failure handling across multi-step reasoning workflows.
• Develop RAG pipeline evaluation frameworks assessing retrieval precision, chunk relevance, context faithfulness, answer grounding, and hallucination rates using tools like RAGAS, TruLens, and DeepEval.
• Lead structured red-teaming and adversarial testing exercises targeting prompt injection, jailbreaks, data leakage, context poisoning, and model manipulation - building and maintaining an evolving adversarial test library.
• Execute fairness, bias, and Responsible AI audits - testing for demographic bias, sentiment skew, representation gaps, and validating explainability mechanisms, citations, and confidence score accuracy.
• Design and run inference performance benchmarks - measuring latency, throughput, token efficiency, and degradation under peak load - and enforce LLM quality gates within CI/CD pipelines on Databricks (AWS).
• Build production monitoring and drift detection pipelines tracking semantic output drift, embedding shifts, retrieval degradation, and anomalous agent behaviors using observability tooling (Grafana, Datadog, CloudWatch).
• Define the AI testing roadmap and quality standards for the program - establishing evaluation metrics, tooling choices, and documentation practices across all Gen AI workstreams.
• Partner with Gen AI engineers, ML engineers, and product stakeholders to embed quality from day one - reviewing prompt architectures, agent designs, and system workflows for testability and risk.
• Continuously research and adopt frontier evaluation benchmarks (RAGAS, MMLU, TruthfulQA, MT-Bench) and emerging AI testing methodologies to keep quality practices at the cutting edge.
All About You:
• Master's/Bachelor's degree in Computer Science, AI/ML, or Software Engineering, with considerable hands-on experience leading AI/ML quality engineering or LLM testing programs in production environments.
• Demonstrated expertise testing LLM and Gen AI systems - including prompt testing, output evaluation, hallucination detection, RAG pipeline assessment, and agentic workflow validation in real production settings.
• Deep hands-on knowledge of AI evaluation frameworks and tooling: RAGAS, DeepEval, TruLens, LangSmith, PromptFlow, Weights & Biases Evals, or equivalent platforms.
• Strong understanding of Gen AI failure modes - hallucination, prompt injection, retrieval grounding failures, context drift, agent loop failures - and proven methods to surface and document them systematically.
• Strong Python programming skills with the ability to independently build test automation scripts, evaluation pipelines, and API-level integration tests; SQL proficiency required.
• Working knowledge of LLM ecosystems - OpenAI, Anthropic, Hugging Face, LangChain/LangGraph - sufficient to understand model behavior, prompt structure, and agent architecture deeply enough to test them rigorously.
• Familiarity with MLOps/LLMOps pipelines (MLflow, Databricks, SageMaker) and experience integrating automated quality gates into CI/CD workflows for AI systems.
• Experience with cloud AI infrastructure (AWS, Azure, or GCP) and observability tooling for monitoring live AI system behavior and output quality in production.
• Strong analytical, communication, and stakeholder management skills - with the ability to translate complex AI failure patterns into clear risk assessments and remediation recommendations for both technical and business audiences.
