About The Position

We're looking for a highly entrepreneurial Marketplace General Manager to build and scale a marketplace from the ground up. This is a hands-on, 01 role spanning strategy, product, operations, partnerships, distribution, and revenue. You'll own the marketplace end-to-end—from solving the initial cold-start problem and building the vendor ecosystem to improving conversion and developing the commercial model.

Excellent communication, negotiation, and relationship-building skills.
