Title and Summary

Agentic AI - Senior Software Engineer

Overview
Mastercard Foundry R&D is seeking a Senior Software Engineer to join the Agentic AI Engineering team.

This is a hands-on role for an engineer who is deeply engaged in applying Generative and Agentic AI to real products, platforms, and developer workflows. You will help build the tooling, services, and reusable patterns that enable teams across Mastercard to experiment, validate, and scale AI-enabled solutions.

We are looking for someone with strong engineering fundamentals, a product-building mindset, and a practical understanding of the patterns and trade-offs behind modern AI systems.
Responsibilites

Build software, tooling, and platform capabilities that support Mastercard’s Agentic AI strategy
Design and implement AI-enabled applications, workflows, and developer-facing capabilities
Develop reusable services, patterns, and integrations for AI and agentic systems
Evaluate models, frameworks, and tools across quality, cost, latency, reliability, and maintainability
Contribute to new product and prototype development from concept through validation
Improve developer experience through automation, AI-assisted workflows, and platform thinking
Partner with product, engineering, and business stakeholders to turn ideas into working solutions
Advocate learnings, prototypes, and best practices across the organization

Experience

Hands-on experience building applications or systems using Generative AI, LLMs, or agentic patterns
Experience with one or more modern AI frameworks and SDKs for agent orchestration, AI application development, or coding-agent workflows (for example LangGraph, OpenAI Agents SDK, Vercel AI SDK, or Codex SDK)
Strong understanding of orchestration, tool-calling, context management, and AI system design trade-offs
Strong software engineering experience building scalable, maintainable production systems
Experience with React and/or Next.js
Strong backend engineering skills in Java and/or Python
Experience with developer tooling, automation, CLI-based workflows, and CI/CD
Familiarity with containers, cloud-native development, and service integration patterns
Experience building products, prototypes, and/or internal platforms with a focus on usability and adoption

All About You

Thrives on creating innovative products and technology solutions in a collaborative, fun environment.
Hands-on, curious, and comfortable working in fast-moving environments
Uses AI as part of daily engineering practice
Brings both engineering depth and a product mindset
Cares about developer experience, quality, and reuse
Communicates clearly and works well across functions
Enjoys learning, experimenting, and helping raise the bar for others
Ability to explain technical problems clearly and succinctly to diverse audiences.

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.
