"We need to hire a DevOps engineer." This sentence reveals a fundamental misunderstanding. DevOps isn't a role you hire for. It's a culture where development and operations work as one team with shared goals and shared responsibility.
What companies think DevOps is:
A person who writes YAML and manages Jenkins
What DevOps actually is:
A culture where the team that builds the software also runs it
Shared ownership of reliability, performance, and deployment
Automation of everything that can be automated
Continuous feedback loops from production to development
