What the job involves

• Cloud Infrastructure Engineers at Mastercard design, build, and operate the foundational platforms that enable our product and service teams to deliver securely, reliably, and at scale
• This role focuses on Azure-based infrastructure, cloud-native services, and automation that power transaction processing, analytics, developer productivity, and self-service delivery across the enterprise
• As a Senior Software Engineer, you will be a highly capable individual contributor with deep technical expertise and increased ownership of design and delivery
• You will lead the implementation of complex infrastructure capabilities, influence platform standards and patterns, and partner closely with service teams to improve reliability, security, and developer experience
• While remaining hands-on, you will provide technical guidance to others and help shape how the team builds and operates cloud platforms
• Own and drive the design, implementation, and operational support of complex cloud infrastructure components and services
• Build scalable, secure, and reusable Azure infrastructure using automation-first and Infrastructure-as-Code practices
• Lead technical design discussions within the team, evaluating tradeoffs and influencing platform standards and patterns
• Enable self-service provisioning capabilities that reduce friction and improve autonomy for service teams
• Actively improve platform reliability, security posture, observability, and cost efficiency
• Troubleshoot and resolve complex, cross-cutting infrastructure and platform issues
• Provide technical mentorship through design reviews, code reviews, and hands-on guidance to less experienced engineers
• Collaborate closely with application, security, and operations partners to ensure platform solutions meet enterprise needs
