Are you a passionate Account Manager ready to conquer the network security market? Then this opportunity is for you!

Account Manager US 

(The Role is based in the US and we will only consider application from people living there)

At Open Systems, we believe great customer relationships are at the heart of long-term success. Until now, our sales team operated in a hybrid model, winning new customers and managing existing ones.
