Job description

Join the Future of Commerce with Whatnot!

Whatnot is the largest live shopping platform in North America and Europe to buy, sell, and discover the things you love. Whether it's trading cards, fashion, electronics, or live plants, our sellers are building real businesses across hundreds of categories. We're building live commerce at a scale that's never been done in the West, and there's no playbook to copy. The people here are shaping how an entirely new industry develops.

As a remote co-located team, we're inspired by our values and anchored in hubs across the US, UK, Ireland, Poland, Germany, and Australia. We move fast, stay close to our users, and focus on the work that drives the most impact.

We're one of the fastest growing marketplaces and were recently named the #1 Best Startup Employer in America by Forbes. Check out the latest Whatnot updates on our news and engineering blogs and join us as we enable anyone to turn their passion into a business and bring people together through commerce.

Role

The Financial Platform team at Whatnot are globally responsible for how our business moves and records money and credit in all customer transactions; 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 have unlocked tremendous growth within and across international territories, while creating exciting new ways for our users to interact and transact on the platform. You’ll collaborate closely with our partner team, Payments - Experience, and with other teams and senior leaders across Whatnot.

To keep the flywheel spinning, we’re looking to make a number of substantial improvements to critical infrastructure supporting payment scale & reliability, diversity of payment options, fraud mitigation, and improvements in transaction modelling and tax to further provide a seamless international marketplace. Each member of the team has a number of individual responsibilities and is trusted to advance an aspect of the domain as an expert in collaboration with the leadership team. Your ability to make good trade-offs, exercise good judgment and communicate effectively is essential to us.

We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our Dublin hub.
