Recurring Payin team owns the Direct Debit API that powers automated payments into Wise. Underneath this, we are building a platform that allows customers to easily schedule top-ups or business collections.

The platform is also built on top of our internal Payin Platform rails; which is a critical component to the Wise money-movement machine and we’re looking for an engineer motivated to come and help us build for this.

We primarily offer APIs for any partner looking to set up automated funding or pre-authorizations. From setting up GBP balance top ups automatically to allowing business partners collect EUR bills monthly without having the customer go through the flow every time; our platform aims to consolidate all these use-cases.

We aim to allow customers to give a one time permission (pre-authorization) for Wise to pull money across any payment method, a USD bank account or a EUR issued bank card; you name it.

Staying safe while you apply

Never pay to apply, interview or accept an offer. ROLIVA never asks you for payment to apply to a job.
Apply only through the official “Apply on the employer’s site” button, on the employer’s own site, and check that a recruiter’s email uses that employer’s own domain rather than a free email address.
Be cautious of an offer made with no real interview, or pressure to decide quickly or share financial details early.
