System administrator, dispatcher and video surveillance operator - how to call a specialist who performs the functions of these three specialties?

Question

System administration

Not so long ago I was offered a job in a Kazakh agricultural company that specializes in the supply of grain abroad, the list of my main duties will include
: all existing technical problems, that is, performing the functions of the most common entry-level system administrator.
2) Performing the functions of an administrator/operator of video surveillance. The technical part - monitoring of all video surveillance equipment, maintaining it in working order, setting up, optimizing work, and, if necessary, calling specialists from the responsible organization to solve critical problems and install new cameras. The operator part - control and monitoring of objects and personnel of the enterprise, timely response, and documentation of all suspicious activities, checking archives, as well as checking the effectiveness of the performance of security duties.
3) Performing the functions of a transport dispatcher - working with Autograph software, tracking and controlling vehicles of the enterprise, checking the performance of GPS sensors, fuel, etc., calling specialists from the responsible organization to solve critical problems, documenting all suspicious actions of drivers, issuing waybills, and as well as monthly reporting, which includes information on the working hours passed by drivers, according to which the accounting department must continue to pay them wages.
Yes, there is a lot of work and responsibility, the range of duties is very wide, but the problem is not even in this ... The problem is that with such a wide range of duties it is difficult to determine what exact specialty should be indicated in the employment contract in order for it to be the most corresponded to reality. Initially, the employer wanted to arrange a job for me in the specialty "Dispatcher", but after a not so long dialogue, I managed to convince him and get carte blanche to choose a specialization (yes, I was very lucky).
Now the stumbling block: what should I indicate to my employer in the employment contract i.e. what specialty should he hire me for? Is it possible to get a job in several specialties at once? concurrently, if so, what are the pitfalls in such employment? Or is it better to apply for one specialty, but it is not clear which one. For example, you can get a job as a system administrator, and in future resumes "experience in administering video surveillance cameras" and "experience with dispatching software" can be indicated as an additional skill - but how correct is all this?
In general, it would seem such a simple question to which I have no answer. Anyone who has had a similar problem in their career, please advise.
+ Another extremely important point, the specialization in the employment contract must be specified in such a way that is valid in Canada. For example, the System Administrator fully complies with the Canadian Classification of Occupations (NOC), but with a vehicle dispatcher and a video surveillance operator, everything is no longer so clear, and I have not yet been able to find an exact analogue of these specialties there.
