Senior Site Reliability Engineer at Cookpad Limited (Bristol, UK)

Cookpad is looking for engineers to join our Site Reliability Engineering team.

In Cookpad, Site Reliability Engineers (SRE's)  are a hybrid between system engineers and software engineers who are responsible for and who take ownership of reliability, automation, and scalability.  

As a software engineer, we mainly use Ruby to automate routine works and build applications which improve scalability and availability. As a system engineer, we manage our servers on AWS to provide service to 68 countries. Configurations and conditions are managed in Ruby.

We flexibly introduce new technology stacks to evolve our infrastructure. For example, currently we use AWS ECS as a container application orchestrator but we also evaluate Kubernetes as our next container application orchestrator and plan to deploy Machine learning products with Kubernetes. We are introducing Prometheus instead of Zabbix to achieve more precise metric collection and scalability.

We also work closely with engineers to advocate sensible, scalable, systems design and share responsibility with them in diagnosing, resolving, and preventing production issues. In the case of incidents, you will triage, mitigate and solve them with product team engineers.

Challenges and technology stacks for SRE change in order to fulfill business goals. As engineers, we believe our activities not only give us great technical challenges but also deliver real value to the world.
