Post-production Opening credits in a Turkish TV series

When a name appears in the Opening Credits as "post-production" only, in which section do I submit that person? Producers? Production Designers? Production Managers? Thank you in advance. Cheers! N.B: that person only appears in the Opening credits. (Most credits for that person have been as "post-production assistant" and "post-production coordinator" and latest as "post-production supervisor").
