Acceptable work experience towards the Charter

PPL… pls help me. I have an offer to work at one of the largest banking firms in US and it is Back to Middle Office kind of role. I will be primarily involved in CDS pricing and settlements. I am concerned regarding the work experience acceptability of this kind of a position towards the CFA Charter. I have 1.5 yrs of experience and currently I am working in a Risk Advisory role with a Big 4 firm, which is accepted towards the Charter since my seniors have already finished their program and earned the Charter. Could someone please advise me on this issue? Thanks a lot. CS.
