Engineering at Brex

Engineering at Brex is about building systems that scale with speed and intention. Our teams span Software, Data, Security, and IT, and operate with high autonomy and deep collaboration. We tackle hard technical problems, own our outcomes, and push for excellence at every level — from architecture to deployment. It’s an environment where engineering is a craft, and builders become leaders.

What you’ll do

As a Staff Software Engineer in Banking, you will help shape the technical direction of one of Brex’s most strategic and complex product areas. The Banking org is both a product and platform org, it owns the Brex Business Account product and AP offerings like Bill Pay and Vendors, and the underlying money movement platform and partner integrations that power those experiences. In this role, you’ll work across customer-facing product surfaces and core financial infrastructure, driving architecture, reliability, and execution across that full stack.

This role is designed for an engineer who can move between long-horizon technical strategy and hands-on execution. You will partner closely with engineering, product, design, data, operations, risk, compliance, and external partners to simplify complex systems, improve reliability, and help the organization deliver ambitious product outcomes without losing sight of operational excellence.

You should be excited to lead through influence, bring clarity to ambiguous spaces, and raise the bar for how we design and operate banking systems at scale.
