Задачи

• 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
• You will work across APIs, data models, and distributed systems where correctness and auditability are non-negotiable, while collaborating with product teams across Brex to extend accounting capabilities without one-off solutions
• Where you'll work
• This role will be based in our São Paulo office
• We are a hybrid environment that combines the energy and connections of being in the office with the benefits and flexibility of working from home

• 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 GL coding and mappings into accounting workflows while preserving explainability and human review
• Participate in on-call rotation and maintain high operational standards for mission-critical systems

• 2+ years of experience building systems in a domain where correctness and reliability were core requirements, such as fintech, payments, financial systems, or another regulated industry (e.g. healthcare, legal)
• Strong curiosity for digging deep into the technical problems, and a track record of owning significant technical scope and delivering high quality solutions
• Experience designing APIs, data models, and platform capabilities that serve many different customer workflows and configurations
• Proficiency in backend technologies (e.g., Kotlin, Java, TypeScript) and comfort with our stack (Kotlin and Micronaut)
• Experience architecting, developing, and testing full-stack applications end-to-end
• Comfort working with databases (e.g., PostgreSQL), event streaming (e.g., Kafka), and distributed systems
• A high bar for engineering standards: code quality, testing, observability, and operational excellence, and a habit of raising that bar in others through review and mentorship
• Strong written and verbal English communication and interpersonal abilities

Будет плюсом

• Direct experience with accounting systems or ERPs such as NetSuite, QuickBooks, Xero, SAP, or Oracle, either building integrations or working with them as a practitioner

• Experience shipping ML- or LLM-powered product features, particularly where explainability and human review matter
• Experience with platform or API products consumed by other engineering teams or external developers
