What does a Reliability Engineer do?


Reliability Engineer(s) – as the title suggests – focus on one core principle of engineering – reliability. They work to prevent failures and enhance the reliability of a product, machine, asset, or equipment. Let’s dive in to take a closer look at the role.

What is Reliability engineering?

Reliability engineering is a sub-discipline of system technology that revolves around reliability in the lifecycle management of a product. Reliability refers to the ability of a system or component to function under specified conditions for a certain period of time. 

Reliability engineering is closely related to security engineering and system security by using common methods for analysis and requiring input from each other. Specifically, reliability engineering focuses on the cost of system downtime, spare parts, repair equipment, personnel, and warranty costs
