I have to proofread a series of translations, and I now have the following problem:

In one of the documents the translator put Produktverantwortlicher der XY-Abteilung as XY Department employee responsible for the product. Since I consider this translation to be too long-winded and unwieldy in a sentence, especially when used repeatedly as in this document, I changed it to XY Department Product Manager.

Now I got another document, along with a note that she thinks that product manager is too specific for produktverantwortlicher Mitarbeiter and that she wants to translate this as product responsible employee.

I am 99.9% sure that product responsible employee is absolutely unidiomatic and not possible in English, but before I say anything I'd like to be 100% sure.

I would like to stick with product manager, but I'm no expert on business terminology. Does anyone else think that this is "too specific"? LEO has product manager for Produktverantwortlicher.

Since I do not consider product responsible employee a viable option, the alternatives would be employee responsible for the product or employee in charge of the product, which I would like to avoid because of the length.

Opinions please?
