Overview

Mastercard is seeking a Senior Software Engineer (Level 7) with experience designing and building agentic systems, treating AI agents as production software components rather than experimental artifacts.

In this role, you will focus on building the platform, orchestration, and runtime capabilities that allow AI agents and tools to execute safely and observably inside market-facing products. You will partner closely with AI Engineers but retain ownership of system level concerns such as identity, authorization, attribution, reliability, and operational controls.
This role is ideal for engineers who excel in building distributed systems and are motivated by applying those fundamentals to modern AI driven architectures.
