Lead Software Engineer Overview: The Accelerators group under the Business & Market Insights - Platform Engineering program at Mastercard is seeking a Lead Software Engineer to drive high-impact technical initiatives that accelerate delivery, improve platform scalability, and enable innovation across the organization. The Accelerators group is leading from the front in making meaningful contributions that allow the B&MI organization to go “faster.” This team is intentionally agile and flexible, not defined by a single technology stack, domain, or rigid process. Instead, it is composed of self-starters and self-unblockers who focus on delivering outcomes while continuously improving how those outcomes shape the next phase of platform evolution. If you're seeking an opportunity to impact a business unit across platform engineering, DevOps, software engineering, and process transformation—while also mentoring and growing others—this position is for you.
