Project description

About the vacancy

Our client is one of the biggest online retailers worldwide with annual revenue of £1 billion. Over the years we helped the client develop web-portals, mobile apps, delivery control systems, staff management tools, data storage, and much more. The systems we’ve built together are in operation 24/7, contributing to the client’s success.

Site Reliability Engineering is a new role, first introduced by Google, that combines the skills of developers and ops to deliver more reliable, scalable software. The goal is to analyze a diverse set of applications (primarily built using Java, Oracle, AWS, Google Cloud services, and several other technologies) and bind them into a reliable self-healing suite, working within defined reliability requirements. This requires proactive work to ensure observability, analyze potential bottlenecks, and suggest their fixes before they become a production incident.

This position may be of interest to DevOps engineers who would like to get closer to the code or get valuable specialization with a focus on JVM stack. The position may also appeal to developers who are interested in how large scale systems operate and what happens to the code is compiled.
