Customer Success Engineer, Enterprise Engineering

Role

The Enterprising Engineering team, nested within our Seller Engineering org, supports the needs of our largest and most complex sellers.

• Solving complex post-sale technical challenges while helping define how Whatnot supports enterprise commerce moving forward.
