How do I hire a good DevOps, fitting my company?
It is a common misbelief that “DevOps” is a role in a company. The word merely denotes an organisational shift in software companies, this shift can be shortly described by the “You build it, you run it!” coined by Werner Vogels:

There is no need to distinguish between building and running, and according to Werner Vogels, it is much better than that:

Giving developers operational responsibilities has greatly enhanced the quality of the services, both from a customer and a technology point of view. The traditional model is that you take your software to the wall that separates development and operations, and throw it over and then forget about it. Not at Amazon. You build it, you run it. This brings developers into contact with the day-to-day operation of their software. It also brings them into day-to-day contact with the customer. This customer feedback loop is essential for improving the quality of the service.

This lesson is interesting, but this particular change in an organization is not always easy to implement.

This shift is concomitant of an increasing importance of continuous integration and deliveries methods. Please note that these ideas are much older than the formalisation of “agile” methodologies, some of them are already present in the NATO Scientific Committee report about software engineering published in … 1968!
While the wording can be overlooked, the short description of the DevOps proposal (this site) mentions “software engineers”:

Beta Q&amp;A site for software Engineers working on automated testing, continuous delivery, service integration and monitoring, and building SDLC infrastructure.


Now if you are looking for a software engineer that can help your team getting started with these methodologies, engage them on this topic. Even if you are not familiar with this topic, following the “You build it! You run it!” slogan you can start from a programming problem and lead the interview towards question about deployment and maintenance of the application.
