Software Engineer II - Backend/Platform Agentic AI

The Portfolio Intelligence (PI) program within Mastercard’s Business & Market Insights (B&MI) division delivers analytics products that help financial institutions understand and grow their card portfolios. We’re building a first-party AI platform that brings agentic, conversational, and generative AI capabilities directly into our products; powering features like natural-language analytics, automated report summaries, and personalized dashboard experiences for thousands of customers worldwide. This is a builder role. You will write code daily, own components end-to-end, and ship production-grade AI-enabled services within a multi-tenant, customer-facing platform. You’ll work alongside senior engineers, architects, and product partners to implement agentic workflows, integrate LLM-powered capabilities into our existing Java/Spring Boot stack, and help operate AI systems in production. About the Role:

• Build and operate services delivering AI-powered features to customers, ensuring correctness, performance, and reliability in a multi-tenant distributed environment
• Implement agentic workflows and LLM integrations from design specifications, including tool calling, retrieval patterns, prompt management, and streaming responses
• Own delivery end-to-end: design, development, testing, deployment, documentation, and production support
• Contribute to CI/CD pipelines, automated testing, and release processes to ensure consistent, reliable delivery
• Monitor, debug, and improve AI systems-resolving production issues, optimizing latency, and maintaining service health
• Collaborate with senior engineers and platform teams to integrate PI-specific capabilities into shared AI infrastructure
• Follow and contribute to engineering best practices for code quality, testing, observability, security, and reliability

• Ensure adherence to Mastercard standards for AI governance, Responsible AI, and data security in a regulated environment All About You:

• Experience building and shipping AI-powered features in production environments
• Strong Java engineering background, including building and maintaining Spring Boot microservices

• Familiar with production operations, including service ownership, incident response, and observability
• Solid testing discipline with experience in unit and integration testing
• Strong communication skills and ability to collaborate across distributed teams
• Proactive ownership mindset-asks thoughtful questions, learns quickly, and improves from feedback and production insights

• Motivated to grow AI engineering expertise and take on increasing technical scope over time Required skills to be considered:

• Strong proficiency in Java for backend and service development
• Experience integrating AI/ML capabilities in production (LLM APIs, model serving, retrieval pipelines, or similar)
• Strong understanding of REST APIs, microservices architecture, and distributed systems fundamentals
• Experience with CI/CD practices, including branching, build automation, quality gates, and deployment pipelines
• Working knowledge of production operations: logging, metrics, monitoring, and incident response

• Experience with cloud platforms (AWS or Azure) Nice-to-have:

• Python experience for AI/ML scripting, experimentation, or tooling
• Familiarity with agentic AI frameworks (LangGraph, LangChain, or similar)
• Experience with Databricks, Snowflake, or similar cloud data platforms
• Experience with RAG patterns, vector databases, or semantic search
• Exposure to prompt engineering and commercial LLM APIs (OpenAI, Anthropic, Azure OpenAI)
• Experience with Kubernetes, Docker, or container orchestration
• Familiarity with analytics platforms, data pipelines, or BI tools
• Experience in financial services or other regulated environments
