Title and Summary
Principal Software Engineer, Software Engineering – File Transfer
About the Role
We’re looking for a Principal Software Engineer to help design, build, and operate Mastercard’s File Transfer platforms, which move critical data securely and reliably between Mastercard and its customers worldwide.
This is a senior individual contributor role for an engineer who enjoys solving complex platform problems, shaping technical direction, and raising engineering standards across teams—without people management.
What You’ll Do
Design and build secure, scalable, and highly reliable services that power large‑scale file and data transfer.
Set technical direction and influence architecture across multiple teams and services.
Lead by example through hands‑on coding, design reviews, and technical mentoring.
Drive end‑to‑end service ownership, including performance, reliability, and operational readiness.
Identify and fix systemic issues, technical debt, and anti‑patterns to continuously improve platform quality.
Partner closely with Product and Operations to deliver features and resolve production issues quickly and effectively.
What We’re Looking For
Deep experience building production‑grade software in complex, distributed systems.
Strong technical judgment and the ability to simplify and improve large, existing platforms.
Comfort working across the full lifecycle: design, build, deploy, operate, and improve.
A collaborative mindset—you influence through expertise, not authority.
Experience with platforms involving secure data movement, integrations, or high‑reliability services is a strong plus.
Why This Role
You’ll work on mission‑critical systems, solve real scale and reliability challenges, and have a meaningful impact on how Mastercard moves data globally—while helping teams around you become better engineers.
Corporate Security Responsibility
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.
