Staff Engineer - Business Spend

Overview

As a Staff Engineer in the Business Spend segment, you shape the architecture of how companies model, process, and pay for spend. You’ll own critical parts of supplier data and invoicing flows while coordinating across product, design, and compliance. You’ll drive cross-team technical decisions, raise the capability of teammates through pairing and clear documentation, and help scale a legacy-to-modern migration. This role offers visibility into customer impact and a chance to tackle hard problems in a fast-growing fintech environment.
