Staff Software Engineer, Payments Orchestration: Customer, Merchant & Configuration Data

Trustly moves money between consumers, merchants and banks across the US. We are building our US engineering hubs in San Francisco and New York, starting with a small group of staff engineers who will take technical ownership of our most critical systems. You will own Payments Orchestration: Customer, Merchant and Configuration Data end to end: its architecture, its reliability, its operation in production, and where it goes next. You'll own the records and configuration every payment depends on: customer records and their uniqueness guarantees, merchant records and settings, the rules configuration for our gaming and enterprise verticals, and the shared configuration and merchant notification services. This is a hybrid role based out of our San Francisco office, with team members in the office Tuesday through Thursday.
