Only your second example is correct. You can't use "since" with time durations. You can use it only with points in time.
"2 years" is a duration, while "2 years ago" is a point in the past (like yesterday, last year or birth)
As the comments advise, it is better to use "for" in such context with time durations.
Neither example is a preferred way of using "since." Here are alternative versions with brief explanations as to how they use references to time.
I have worked here for two years.
This first example uses the speaker's current moment in time as the point of reference to express how long he or she have been doing something. That the speaker may have been doing something else before two years ago is irrelevant with this statement.
I started working here two years ago.
This second example uses a past moment in time as the point of reference to express how long the speaker has been doing something. Again, that the speaker may have been doing something else before two years ago is irrelevant with this statement.
It has been two years since I started working.
This third example uses a past moment in time as the point of reference to express how long it has been since something changed. This is the important distinction: what the speaker was doing before two years ago was important. The change in condition
is more important than what has happened since.
I haven't been unemployed since two years ago.
This fourth example uses a past moment in time as the point of reference to express how long it has been since something changed. However, this time what the speaker was doing before the moment of change is more important than what the speaker was doing after the moment of change.
We see this perspective of the change in condition
in the official definition. From the Merriam-Webster Dictionary:
Since [1]:from a definite past time until now (has stayed there ever since), [2]:before the present time (long since dead), [3]:after a time in the past (has since become rich).
