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 Senior Software Engineer on the Accounting Engineering team, you will build the platform and product surfaces that turn Brex activity into accurate, usable accounting data. Accounting is a core component of our product offering and often a strategic differentiator. Your focus will be the systems finance teams depend on to close their books: reusable accounting records, rules, and mappings, reliable ERP integrations with NetSuite, QuickBooks, Xero, and others, and AI-native automation that predicts accounting work while keeping customers in control.

We currently require a minimum of three coordinated days in the office per week: Monday, Wednesday, and Thursday. As a perk, we also have up to four weeks per year of fully remote work. Responsibilities • Build and maintain the core accounting platform, including reusable records, rules, mappings, and versioned APIs that Brex product teams and external partners extend without one-off solutions. • Own ERP connectivity end-to-end, building and scaling reliable integrations with NetSuite, QuickBooks, Xero, SAP, and Oracle, including sync, error recovery, and rate-limit handling. • Implement customer-facing close experiences for reviewing, configuring, reconciling, and exporting financial activity in our React/TypeScript dashboard. • Collaborate with Product, Design, Data Science, and Implementation teams to translate complex accounting and ERP concepts into experiences that feel simple for finance teams. • Design distributed systems where correctness is non-negotiable, making idempotency, reconciliation, traceability, and proactive issue detection first-class parts of the architecture. • Own problems end-to-end, from user experience and API design to data models, scalability, and ongoing observability. • Work with ML models in production, integrating predicted
