First of all a little background:
Fresh employed (<2 months) for a new - permanent - position
~5 years experience in IT-Sector
IT-Advisor
Germany
Service Company in Pharmasector
<15 employees
**.000.000 turnover
The Situation:
My responsibilities go far beyond the job description.
I was hired as IT-project staff but this is only a fraction of my role here.
Actually, I'm the only person with IT-Knowledge in a company whose service relies on quite (way too) complex IT-Processes. These processes, the architecture, Service Providers and so on, have to be refactored and managed.
The job is actually a quite big thing and not as banal as I thought in the first place. The management is aware of that, but due their lack of IT-knowledge (they say) they where unable to write a proper job description. I now write my own description which will be part of the working contract.
Within the next 6-12 months, I'll be almost irreplaceable. Everything I do should have been done years ago (literally). The IT structure reminds me of a tower of razorblades. God knows why this still stands up, but it doesn't take a lot for everything to fail at once.
I'm perfectly fine with the job, it's an awesome challenge within a good friendly and high budget environment.
My direct superior (Not part of the management) told me, that there where only 2 other candidates which where suitable and that they chose me for the social fit (I fit perfectly in the team).
The Problem:
I've sold myself far below value.
Looking at national salary statistics, companies financial situation and my (now gathered) knowledge of that position, there is a discrepancy of factor 2-3. I think that's huge and I feel "way too cheap".
I do not want to ask for the double or triple. Let's say within the next 3 years, I want my salary to be doubled from the current. By that, it would be slightly below the median for such a position for a person of my experience (8 years then).
How and when is such a topic addressed best?
