Senior Backend Product Software Engineer, Payments

The Payments Team is responsible for building and maintaining Dropbox’s internal payments infrastructure — a robust, in-house alternative to third-party providers. The team supports all critical components of the financial ecosystem, including payment processing, authentication (e.g., 3DS), transaction flows, risk management, and revenue recognition. As part of a strategic initiative to expand global presence and accelerate opportunities in Payments-driven revenue, Dropbox is building an entirely new Payments team based in Poland, including engineering manager, product manager, and data scientist. Members of this new team will have the opportunity to shape the technical direction, culture, and processes of a high-impact engineering group from the ground up.

• Collaborate closely with product managers, designers, and cross-functional partners (Billing, Financial Data Engineering, etc.) to deliver reliable payments functionality.
