Staff Software Engineer, Payments

Whatnot is the largest live shopping platform in North America and Europe to buy, sell, and discover the things you love. We’re re-defining e-commerce by blending community, shopping, and entertainment into a community just for you. As a remote co-located team, we’re inspired by innovation and anchored in our values. With hubs in the US, UK, Germany, Ireland, and Poland, we’re building the future of online marketplaces –together.

From fashion, beauty, and electronics to collectibles like trading cards, comic books, and even live plants, our live auctions have something for everyone.

And we’re just getting started! As one of the fastest growing marketplaces, we’re looking for bold, forward-thinking problem solvers across all functional areas. 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.

The Payments - Treasury 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.

Curious about who thrives at Whatnot? We’ve found that embodying a low ego, growth mindset, and high-impact drive goes a long way here.
