SREs are responsible for the big picture of how our systems related to each other, we use a wide range of tools and approaches to solve a broad spectrum of problems. Practices such as limiting time spent on operational work blame less post-mortems and break things to proactively identify potential outages are our bread and butter. SRE's culture of diversity, intellectual curiosity, problem solving, and openness is key to its success.

• Engage and improve lifecycle of services—from inception and design, through deployment, operation, and refinement

• Support services before they go live through activities such as system design consulting, developing software platforms and frameworks, capacity planning and launch reviews

• Help to maintain services once they are live by measuring and monitoring availability and latency

• Scale systems sustainably through mechanisms like automation and evolve systems by pushing for changes that improve reliability and velocity

• Educate and practice sustainable incident response and blameless post-mortems

• Be on an on-call rotation to respond to PayU systems availability incidents and provide support for service engineers with customer incidents

• Design, build and maintain core infrastructure pieces that allow us scaling to support hundreds of thousands of concurrent payments

• Educate engineers on how to approach and debug production issues across services and levels of the stack
