Role Overview As a Backend Engineer in the Money team, you build and maintain backend services behind customer accounts and money movement, working on well-defined tasks with guidance from senior engineers. You write clean, tested code, learn how banking-grade systems stay exact and auditable, and grow quickly toward owning features on your own. Build and maintain backend services and APIs for accounts, balances, transfers and payments, following the team's designs and standards. Deliver well-scoped tasks from implementation to production, with unit and integration tests. Follow the rules of money handling: exact amounts, idempotent requests, clear transaction states and audit trails. Help with integrations with banks and payment partners, and with daily batch and reconciliation jobs. Take part in code reviews, both receiving and giving feedback, and learn from them. Investigate bugs and production issues with help from senior engineers, and fix them with tests that prevent them from coming back. Write clear technical notes and documentation for the work you do. Ask questions early, raise risks and communicate progress to your team, Product and Operations.
