About the role
Are you a born problem solver who loves to figure out how something works?
Do you have a low tolerance for manual work and look to automate everything you can?

The Business Operations Organization is the production readiness steward for Mastercard products. As a Business Operations Site Reliability Engineers, we are responsible for ensuring that our platform is stable and healthy. We break down barriers to run our products by fostering developer run ownership and empowering developers to build resilient products. We support our developers during the application build phase in software run principals that includes operational design, automation, capacity planning, monitoring that leads to fault-tolerant, scalable products. We see the big picture and help create and enforce operations standards while facilitating an agile and learning culture.

We support daily operations with a hyper focus on triage, root cause by understanding the business impact of our products and subsequently performing blameless post-mortems. The goal of every Business Operations team is to shift left to be more proactive and upfront in the development process, and to proactively manage production and change activities to maximize customer experience and increase the overall value of supported applications. Business Operations teams also focus on risk management by tying all our activities together with an overarching responsibility for compliance and risk mitigation across all our environments.

Ultimately, the role of Business Operations is to align Product and Customer Focused priorities with Operational needs. We regularly review our run state not only from an internal perspective, but also understanding and providing the feedback loop to our development partners on how we can improve the customer experience of our applications.
