The salary and terms are under negotiation at the moment. The agreement between Finnair and the union that represents the mechanics (IAU, ilmailualan unioni) has ended and is being negotiated as we speak.
I work for Finnair, not for the regional side but line maintenance anyway.
I can try and tell you what you want to know.
P.S. I doubt the company is hiring at the moment since they just "gave the boot" to a whole lot of people this summer in order to save on costs.
