Title and Summary

Overview:

Mastercard's Operational Intelligence team is building the next generation of data products and AI solutions that help customers access and use operational insights in new ways. As AI agents move from POC to production, their behavior keeps changing in real time: the context they retrieve, the skills they select, how they resolve exceptions. These agents are never really “finished.” They keep learning from production outcomes, so their reliability, safety, and trustworthiness need to be actively operated, not just monitored. That is the job of AI Ops: making sure each agent’s reasoning stays correct, its context stays current, and its behavior stays governed as it learns.

Role:

• Own end to end production monitoring for one or more AI agents, tracking key metrics, KPIs, accuracy, latency, SLA breaches, guardrail triggers, and out of scope rates through dedicated observability dashboards
• Serve as L1/L2 production support, providing first response monitoring, triage, and escalation to tech teams as new agentic services go live
• Identify and diagnose issues by monitoring eval scores and drift alerts, inspecting failing traces and patterns, and classifying root causes such as intent, tool, parameter, or hallucination errors
• Evaluate whether the agent’s reasoning remains correct in production, checking whether context retrieval stays current, whether resolutions match ground truth, and whether the learning loop is drifting
• Monitor and manage post production reliability, including API and authentication failures and issues originating from external AI endpoints, to protect revenue generating, client facing agents
• Partner with AI Engineering to prioritize fixes, run experiments on prompts, context, and routing in Dev, and validate improvements via evals before handing off proven changes for deployment
• Embed governance within the agent’s learning loop so that approval workflows and audit logging travel with every production change, rather than being added after the fact

All About You:

• Experience monitoring or operating production AI/ML or agentic systems, including observability, evaluation, and drift detection practices
• Strong analytical skills to diagnose root causes across intent classification, tool selection, parameter errors, and hallucination patterns
• Understanding of AI/LLM observability concepts such as tracing, telemetry, guardrails, and evaluation engineering including benchmarks, automated evals, human review, and regression testing
• Familiarity with governance, compliance, and responsible AI practices such as PII detection, access control, audit logging, and policy enforcement is a plus
• Ability to work independently alongside existing Tech teams while owning a dedicated agent’s post launch health
• Excellent communication skills to translate production signals into clear, prioritized asks for AI Product and AI Engineering teams

• Comfort working in a fast evolving environment where the process itself, not just the throughput, is what is being continuously operated on and improved

Corporate Security Responsibility

All activities involving access to Mastercard assets, information, and networks comes with an inherent risk to the organization and, therefore, it is expected that every person working for, or on behalf of, Mastercard is responsible for information security and must:

• Abide by Mastercard’s security policies and practices;

• Ensure the confidentiality and integrity of the information being accessed;

• Report any suspected information security violation or breach, and

• Complete all periodic mandatory security trainings in accordance with Mastercard’s guidelines.
