Our Purpose

Mastercard powers economies and empowers people in 200+ countries and territories worldwide. Together with our customers, we’re helping build a sustainable economy where everyone can prosper. We support a wide range of digital payments choices, making transactions secure, simple, smart and accessible. Our technology and innovation, partnerships and networks combine to deliver a unique set of products and services that help people, businesses and governments realize their greatest potential.

Title and Summary

Principal Software Development Architect

Principal Software Development Architect
Overview
As a Principal Software Architect for Mastercard Commercial Solutions, you will play a critical role in shaping the architecture of a global B2B payments platform designed for scale, security, and performance. This platform supports high-throughput, mission-critical financial transactions and is central to Mastercard’s vision of transforming how businesses manage payments.
You will lead the design of secure, resilient, and scalable systems, mentor engineering teams, and collaborate closely with product and cross-functional stakeholders to bring complex solutions from concept to production. This role demands deep technical expertise, a strong sense of ownership, and a bias for action.
________________________________________
Role Responsibilities

Define and drive high-level architecture and design for core platform capabilities with a focus on security, resiliency, and high throughput.
Lead the creation of technical blueprints, service contracts, and architectural patterns that guide implementation across teams.
Collaborate with product managers and business stakeholders to translate requirements into scalable, secure, and performant solutions.
Provide technical leadership and mentorship, guiding teams through design elaboration, implementation, and delivery.
Ensure alignment with Mastercard’s architectural standards and best practices, including 12-factor app principles and cloud-native design.
Conduct design and code reviews to ensure architectural integrity and adherence to non-functional requirements.
Partner with other architects and engineering leaders to evolve the platform’s architecture and technical roadmap.
Champion a culture of high accountability, ownership, and continuous improvement.

________________________________________
All About You

Proven experience designing and delivering high-volume, secure, and resilient systems in the fintech or payments domain.
Deep expertise in microservices architecture, distributed systems, and cloud-native technologies (e.g., Kubernetes, PCF, AWS/GCP/Azure).
Strong understanding of non-functional requirements such as high availability, performance, scalability, observability, security and fault tolerance.
Hands-on experience with Java, Spring Boot, messaging systems (Kafka, RabbitMQ), and relational databases (Oracle, PostgreSQL).
Experience with J2EE Architecture (e.g. SpringBoot, Jenkins), with Oracle MAA
Experience working in Agile environments, with a strong focus on iterative delivery and continuous feedback.
Excellent communication and collaboration skills, with the ability to influence across technical and non-technical audiences.
Passion for mentoring and growing engineering talent, and for building a strong engineering culture.
A proactive mindset with a bias for action and a commitment to delivering high-quality solutions.
Familiarity with front-end technologies and frameworks (e.g., Angular) is a plus.

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.
