AI at Brex
AI Engineering at Brex is redefining how businesses run their finances by building intelligent, autonomous systems directly into the Brex platform. Our teams develop AI agents that don’t just surface insights—they take action, optimizing spend, managing workflows, and making real-time decisions on behalf of our customers. By deeply integrating proprietary financial data with product and platform infrastructure, we’re turning complex financial operations into simple, automated experiences and setting a new standard for how modern finance works.
What you’ll do
You’ll be the senior technical owner of the Brex Assistant: a consumer-facing conversation product and will lead the rollout of the Assistant experience — defining what “great” looks like, sequencing capabilities deliberately, and shipping a product that is reliable, opinionated, and genuinely useful. You’ll write a significant amount of production code, set the quality bar, and shape how agentic systems integrate with Brex’s core workflows.
This is a deeply product-driven role. Success is measured by better outcomes for customers — higher-quality expense documentation, stronger policy compliance, and less time spent clicking around Brex.com — not by novelty or research output.
Where you’ll work
This role will be based in our San Francisco 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. We currently require a minimum of two coordinated days in the office per week, Wednesday and Thursday. Starting February 2, 2026, we will require three days per week in office - Monday, Wednesday and Thursday. As a perk, we also have up to four weeks per year of fully remote work!
