💻 Role

The Financial Platform team at Whatnot is fundamental to the company's global operations.

• Develop scalable infrastructure that enables Whatnot to launch new markets, products, and ways for buyers and sellers to transact.
• Make thoughtful technical trade-offs across correctness, reliability, speed, and scalability in systems where accuracy is critical.
• Own projects end-to-end, from understanding the problem and designing the solution through launch and iteration.
• Partner across engineering, product, finance, and operations to solve complex financial and marketplace problems.
• Help shape the architecture and technical direction of Whatnot’s financial platform as the business scales.
•
