Senior Software Engineer, Release Infra

About the role

Join Brex as a Senior Software Engineer, Infrastructure (Release Engineering) and take ownership of the critical systems that orchestrate how our company ships software safely and at scale. You will design, build, and operate the release infrastructure that powers Brex's deployment pipelines, observability workflows, and incident management processes on a global scale. In this role, you will partner closely with product, platform, and operations teams to ensure every release meets our high standards for safety, speed, and reliability while our infrastructure scales securely to support tens of thousands of the world's best companies. You will drive the technical strategy for our release and observability systems, championing automation and reliability so our builders can move fast without sacrificing stability. You will proactively identify and mitigate risks across the release stack, define and monitor key performance indicators, and mentor engineers to elevate the entire organization's engineering craft. This is an opportunity to shape the future of how Brex delivers software and solidify your impact as a leader in infrastructure and reliability.

Practical notes

This role is based in our San Francisco office and operates in a hybrid environment that combines the energy of the office with the flexibility of remote work. We require a minimum of three coordinated days in the office per week on Monday, Wednesday, and Thursday. As a perk, we also offer up to four weeks per year of fully remote work.
