Generally speaking there is little standard terminology for job titles. What is called "Infrastructure Engineer" at company A may be called "DevOps engineer" at company B, and "Deployment Ninja" at company C. When looking for a job your best bet is probably to search for specific skills, not job titles. Personally I would call what you are interested in DevOps (I only skimmed the blog post). To me an infrastructure engineer sounds like someone designing and implementing the infrastructure of a distributed backend system, not someone dealing with deployment.
