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, Infrastructure (Release Engineering) at Brex, you will design, build, and operate the core systems that power Brex’s release, observability, and incident management processes. You will partner closely with product, platform, and operations teams to ensure releases are safe, fast, and reliable, and that our infrastructure scales securely as Brex grows.
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 on Monday, Wednesday and Thursday. As a perk, we also have up to four weeks per year of fully remote work!
Responsibilities
- Design, build, and maintain the release infrastructure that powers Brex’s deployment pipelines and incident workflows
- Drive technical strategy and architecture for release and observability systems, making them more scalable, reliable, and secure
- Collaborate with product, engineering, and operations partners to ensure Brex’s releases are safe, predictable, and low-friction
- Identify and deliver improvements to the end-to-end release process (from code merge to production) to reduce risk and cycle time
- Build and evolve tooling for observability and incident response, enabling fast detection, triage, and resolution
- Proactively identify and mitigate risks in our release and infrastructure stack, including performance, reliability, and security concerns
- Define, instrument, and monitor key metrics for release engineering (e.g., deployment frequency, change failure rate, MTTR) and use them to guide improvements
- Partner with other infrastructure and product teams to debug complex production issues and drive long-term fixes
- Contribute to and champion best practices in release engineering, reliability, and operational excellence across the organization
- Mentor other engineers on the team, providing technical guidance and code reviews to elevate the overall quality of our infrastructure
- Stay up-to-date on emerging tools and practices in release engineering, observability, and SRE, and bring relevant ideas into Brex’s stack
Requirements

- Strong proficiency in backend programming languages (e.g., Go, Java, Kotlin, or Python) with a focus on reliability and performance
- Hands-on experience with CI/CD and release pipelines (e.g., GitHub Actions, CircleCI, Buildkite, Argo, Spinnaker, Jenkins) including build, test, and deployment automation
- Experience architecting and operating scalable, high-availability distributed systems on cloud platforms (e.g., AWS, GCP, Azure)
- Deep familiarity with containerization and orchestration (e.g., Docker, Kubernetes) and infrastructure-as-code (e.g., Terraform, CloudFormation)
- Experience designing and maintaining observability tooling (metrics, logs, tracing) and integrating it into incident response workflows
- Strong understanding of reliability and SRE practices, including SLIs/SLOs, error budgets, and incident management best practices
- Experience designing and optimizing data storage systems (SQL and/or NoSQL) for operational and observability use cases
- Proven track record of improving release processes (e.g., reducing deployment risk, increasing deployment frequency, automating rollbacks)
- Comfort working cross-functionally with product and other engineering teams to debug complex production issues and ship changes safely
