Senior Site Reliability Engineer
About The Position
The Transaction Stream Business Operations (BizOps) team is seeking a Site Reliability Engineer to help solve problems, build and support CI/CD pipelines, and advance DevOps automation and best practices at Mastercard. BizOps serves as the production-readiness steward for its platform, partnering closely with developers to design, build, implement, and support technology services. The role ensures that availability, capacity, performance, monitoring, self-healing, and deployment automation are addressed throughout the delivery process. BizOps supports daily operations with an emphasis on triage, root-cause analysis, and understanding product business impact. The team aims to shift operational work earlier into development, proactively manage production and change activities, improve customer experience, and increase the value of supported applications. It also contributes to risk management, compliance, and risk mitigation across environments; streamlines and standardizes application support; and communicates with internal and external partners to align product and customer priorities with operational needs. The engineer will engage across the service lifecycle, from inception and design through deployment, operation, and refinement. They will support services before launch through design consultation, capacity planning, and launch reviews, and maintain live services by monitoring availability, latency, and system health. The role includes sustainable incident response, blameless postmortems, and holistic troubleshooting across the technology stack to improve recovery times. The engineer will work with a global team across multiple technology hubs and time zones and share knowledge with and mentor junior resources. For team members supporting the DevOps pipeline, responsibilities include designing and enhancing Chef-based deployment automation, using Jenkins to orchestrate builds and integrate pipeline tools, supporting code deployments to lower environments, and developing Git-based code-management strategies for parallel deployments across environments. The role also supports validation and operational gating as software moves to higher environments, with an emphasis on automating manual processes.
