Structuring vs Sales

Structurers consistently communicate with traders to set up parameters (e.g. PnL margin, shifts in FX/IR/Credit curve, and other relevant adjustments) when pricing for structured payoffs to be quoted to salespeople (who will then quote the price to the client). 

Depends on each bank. Bigger banks might have their own "structured notes trading desk" (acting sort of as the moderator) who will then hedge each leg collaboratively with relevant other trading desks (IR options desk, FX desk, etc) for every structured note issuance. But for medium/smaller banks with no "structured notes trading desk", then each leg will go directly to each of the relevant trading desks. Structurers act as the moderator in this case.

For structured swaps, structurers will deal directly with relevant trading desks (e.g. rates options desk), unlike notes. More sophisticated sales will propose ideas to structures and ask us to price based on their idea. For less technical sales, structurers/traders are the one who typically push the products to the sales and nudge them to promote structured notes/swaps to their clients. It is important for structures to gauge what each salespeople want to sell to their clients and how sophisticated they are in terms of structured products understanding.

There's typically more focus on primary issuance/origination, but secondary market for structured products can also be traded OTC (e.g. secondary note issuance or restructuring).

I think it varies banks to banks. My hypothesis is that it is easier to move from structuring to structured product sales than the other way around - since structures know how to use the pricing models well (since they interact with quant and traders often), while sales most often just interact with structures (and receive the price quote from structures without the need of using the pricing models).
