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 Software Engineer II on the Cloud Infrastructure team, you will join a highly competent, senior group of engineers responsible for the foundational AWS ecosystem that powers Brex. Your primary focus will be working on our high-priority Business Continuity and Disaster Recovery (BCDR) initiative to completion, a critical company-level priority that ensures multi-region infrastructure resilience. You will work across Kubernetes, networking, and databases to build systems that scale with speed and intention, while collaborating with teams across the entire organization to drive the adoption of modern cloud infrastructure changes.

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. 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.

• Operational Expertise: Experience with incident response and maintaining highly available production systems.


• Public Cloud Depth: Strong hands-on experience with AWS services and infrastructure-at-scale.


• Collaborative Mindset: Strong communication skills with the ability to coordinate complex changes across multiple autonomous engineering teams.


• Engineering Background: Professional experience in software or systems engineering, with a focus on building scalable systems.

Bonus points

• Infrastructure as Code: Experience using Terraform to manage complex, multi-account environments.


• Resiliency Engineering: Prior experience with BCDR planning, multi-region rollouts, or disaster recovery frameworks.


• Optimization: Background in cloud infrastructure cost optimization or database performance tuning.


• Language Proficiency: Experience with Go, as it is a core part of our tech stack.
