Job overview

About the role

Brex is hiring a Senior Software Engineer for its Operational AI team in São Paulo, focused on the Agents Platform: the internal platform used to build, evaluate and run AI agents in production across onboarding, support and go-to-market workflows.

What you'll do

Own the technical direction and roadmap of the Agents Platform together with Operational AI leadership and partner teams.
Build platform capabilities such as tool calling, multi-step agent loops, multi-turn execution and secure access to internal data and services.
Evolve evaluation and quality systems, including datasets, labeling, run comparison and regression testing for non-deterministic systems.
Improve reliability, security and observability for business-critical flows, covering durable async/batch execution, authorization, cost attribution and incident response.
Drive adoption through clear contracts, paved roads and documentation, and mentor engineers via design and code reviews.

Requirements

5+ years of software engineering experience building and operating production backend systems.
Production experience shipping LLM-powered systems: orchestrating model calls, structured outputs and quality evaluation.
Hands-on daily use of AI coding tools such as Claude Code or Cursor.
Experience with distributed and asynchronous systems (retries, idempotency, backpressure, observability) and a platform/developer-experience mindset.
Strong communication and English proficiency; interviews are conducted in English.

Hybrid role: three coordinated office days per week (Monday, Wednesday, Thursday).
