When I started my job, my job description said I was a SystemsEngineer.

What I do is not engineering. There is little in the way of strictly documented process, I don't use mathematical modelling, I don't "engineer systems." I have no faith that if I were to build a bridge, it'd survive a car, let alone an earthquake.

It definitely doesn't fit the definition "The application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of efficient and economical structures, machines, processes, and systems."

So, I don't call myself an engineer. I tried to think of a new title -- "PC Solutions Specialist" is almost there, but it has the whole ring of "Petroleum Transfer Technician" about it. If people ask what I do, I say I'm a computer consultant.
