Partner across teams to solve complex problems and deliver outcomes quickly
Mentoring engineers and raising the bar for technical excellence

What We’re Looking For

Ability to operate with urgency, make decisions quickly, and adapt to change
Exceptional problem-solving skills — especially in ambiguous, high-pressure situations
Experience influencing across teams and driving technical strategy at scale
Interest or experience in applying AI to software engineering workflows

Why Join Us?

Work on high-impact, global-scale systems
Be part of a team defining the future of AI-enabled engineering
Collaborate with top engineering talent across Mastercard
Shape platforms that power critical financial infrastructure worldwide
