Automate everything — from infrastructure to deployments, focusing on self-healing systems and zero-touch support.​
Develop and Run chaos / failure tests to help SRE teams find weaknesses before they become incidents.​
Improve service reliability, availability, and scalability through engineering and automation.​
Develop shared tools and platforms for all teams to use (CI/CD pipelines, monitoring, failover mechanisms).​
Partner with SRE and development teams in CLS to define and measure service quality (SLI/SLOs).​
Secure our platforms following top security and compliance standards ​
Document what you build so others can easily adopt and improve it.
