Title and Summary

Lead Agentic AI Designer

Overview
Mastercard Services' Operational Intelligence (OI) team is expanding its AI platform with agentic AI and large language model (LLM)-driven autonomous systems. This role focuses on designing, building, and scaling enterprise-grade, multi-agent AI platforms that power critical operational workflows.
This position begins as a hands-on individual contributor with end-to-end ownership of architecture and delivery. Following a successful initial launch, the role is expected to evolve to include people leadership responsibilities.

The Lead AI Engineer, Agentic AI serves as a senior technical contributor, driving architecture, implementation, and production readiness while partnering closely with Product and mentoring other engineers. They will design and deploy large-scale LLM applications and autonomous agent systems integrated with Mastercard's enterprise platforms. This role emphasizes production-quality engineering, reliability, observability, and close collaboration with product partners to move solutions from proof of concept through MVP and into production.

What You'll Build
Agent-based solutions for:
• Reconciliation workflows
• Transaction insights and anomaly detection
• Operational AI copilots
• Systems that evolve from analytics and insights into decision support and autonomous execution

The Role

Agentic AI & LLM Engineering
• Design, build, and deploy LLM-powered applications and multi-agent systems.
• Architect agent workflows including memory strategies, tool integration, guardrails, and human-in-the-loop (HITL) patterns.
• Implement retrieval-augmented generation (RAG) and context engineering using platforms such as Mem0 and Redis.
Platform & Data Integration
• Integrate agentic systems with enterprise data platforms, including TI, MEDI, and OR.
• Develop reliable, scalable backend services using Python, APIs, and distributed system patterns.
• Embed agentic intelligence into payment and operational workflows.
Production Readiness & Reliability
• Drive observability, evaluation, and system reliability for production AI services.
• Implement monitoring and evaluation approaches to support availability, accuracy, and system performance.
• Ensure AI systems meet enterprise standards for scalability, security, and operational excellence.
Delivery, Product Partnership & Mentorship
• Partner with Product to take solutions from proof of concept to MVP and production deployment.
• Mentor engineers and establish best practices for agentic AI development.
• Contribute to technical standards, patterns, and shared frameworks across the team.

All About You
• Strong experience building AI/ML or backend systems using modern engineering practices.
• Hands-on experience developing LLM-powered applications, RAG pipelines, and agent-based systems.
• Proven experience delivering production-scale services in distributed environments.
• Strong proficiency in Python, APIs, and distributed systems design.
• Ability to independently own complex technical problems and drive them to production.

Technical Skills:
• Retrieval and context strategies: RAG, vector-based retrieval
• Engineering stack: Python, APIs, distributed systems, cloud-native platforms
• Observability, evaluation, and reliability for AI systems
• Preferred Qualifications
• Experience with agentic AI systems and autonomous workflows
• Exposure to fintech, payments, or regulated environments
• Experience with vector or graph databases
• Cloud deployment experience
