Senior Software Engineer - Money Movement

About the team

The Innovation team sits at the center of NMI's money movement strategy. Formed through NMI's acquisition of Dwolla, we build and evolve the bank payment platform NMI's partners rely on, spanning open banking, push-to-card, account verification, and new payment rail integrations.

We work asynchronously, communicate often, and expect blockers to be surfaced early. Psychological safety and continuous improvement are how we keep our high pace sustainable.
