Senior Software Engineer - Card Network Integration

Description

The team is the Network File Integration group, which builds software for batch and event-driven processing of card network settlement and transaction data. The role is a senior software engineer position on that team.

The company runs a card issuing platform that lets businesses issue cards, authorize transactions, and manage payment operations in real time. It is an early player in embedded finance.

You will own projects that support the team's quarterly goals and work out your own approach to open-ended problems that have no clear answer yet. You will work with your team and with partners across other functions.

This is an existing vacancy.

The hiring process has five steps: application submission, a recruiter video call, a coding interview followed by a video call with the hiring manager, a virtual onsite made up of three 60-minute calls, and then an offer.
