Seems to me like the first thing you need to do is sit down and define what you want out of life in career terms and how this job will help you achieve it.

You are being offered a job which is a big step up for you, at a salary which is a very good salary by Swiss standards and an opportunity to help define your role. The job is with a large company so there is bound to be plenty of opportunity for advancement. I would expect that if you are doing a good job you should be well able to push the salary up in the next 12 - 18 months or so, or else find another position within the company. I'd look on that as a good opportunity, not to be missed if it fits in with you career plans.

Look at it from the other side, they are bring someone in from abroad, with an unproven record in this area, to take up a new type of role in their company. And you are expecting them to pay top end of the market rates.... if they do decide to up the salary they may also decide to lower their risk level by finding someone with experience to match the salary...

I you have the same experience and track record as the guys that command the big bucks in this area, then by all means depand the salary and don't accept lower. But if not, just be careful that you are not passing up a good opportunity.

Good luck whatever you decide to do.
