Rakuten Symphony

Rakuten Mobile Network is world’s first fully virtualized cloud native network. RAN is completely Open RAN 3GPP compliant design. Horizontal cloud is deployed in Far edge, edge Regional and Central DCs. 4G and 5G services have been launched commercially in Japan. Rakuten is going to bring its network architecture to the world through Symworld. The final goal is to offer telco companies around the world a secure and open mobile network at high speed and low cost. We provide access to Rakuten Mobile’s network design combining virtualization and automation, so that customers can purchase and deploy their network wherever they are in the world. Together with our partners and suppliers, Rakuten Symphony in Germany will establish an end-to-end Service Experience Centre (SxC) to operate the network with a vision of superior customer experience, highest end-to-end service quality and minimal defects. We will Integrate DevOps into the conception of “Mobile as a Software” to proactively plan and build operational stability in the software. Our operating model values lean and agile end-to-end operations processes, close collaboration, and cooperation (teamwork is key!) and a high degree of effectiveness with no duplication of work. The Service Reliability Engineering (SRE) is a central part of our Dev Ops vision and combines software &amp; systems engineering and operations to build and run large-scale, massively distributed, fault-tolerant systems. SRE ensures that Rakuten’s services have reliability, uptime appropriate to customer's needs and a fast rate of improvement. Additionally SRE’s will keep an ever-watchful eye on our systems capacity and performance. Rakuten Symphony is continuously focused on optimizing existing systems, building world class infrastructure and eliminating guesswork through automation. As a junior SRE team, you’ll have the opportunity to manage the complex challenges of scale which are unique to Telco Cloud, while using your expertise in managing complex systems, trend analysis, observability, and large-scale system operations. Together with your team of Service Reliability Engineers you will provide scalable, reliable, durable, and secure Global Cloud services for all our Telecom products hosted on the 1n1 network. You will continuously work with the product organization to automate and optimize for delivering better performance, availability and reliability metrics year on year.The Senior Cloud SRE will be measured on their success to deliver on service availability SLAs and KPIs on a consistent basis and on the ability to eliminate redundancy and drive optimization in Operations.
