💻 Role

The Payments - Treasury team at Whatnot are globally responsible for how our business moves and records the money in every customer transaction; and how taxes, customs, returns, refunds and more just work no matter where our customers are in the world.

We are deeply connected with the foundations of our business and unlock tremendous growth within and across international territories, while creating exciting new ways for our users to transact. You’ll collaborate closely with our sister Payments - Experience team, and with other teams and senior leaders across Whatnot while doing so.

To achieve these goals, we’re looking to make a number of substantial improvements to our systems including critical areas of the business like payment scale & reliability, increased payment options, fraud mitigation, and advanced shipping options and improved delivery times with a focus on providing a seamless international marketplace.

Each member of the team has a lot of individual responsibility and many more freedoms, so we need to hire people we can trust.

Your ability to make good trade-offs and exercise good judgment is essential to us.

Team members in this role are required to be within commuting distance of our Dublin, Ireland hub.
