Working at Brex allows you to push your limits, challenge the status quo, and collaborate with some of the brightest minds in the industry. We’re committed to building a diverse team and inclusive culture and believe your potential should only be limited by how big you can dream. We make this a reality by empowering you with the tools, resources, and support you need to grow your career.

Engineering at Brex

The Engineering team includes Data, IT, Security, and Software, and is responsible for building innovative products and infrastructure for both internal and external users. We have multiple autonomous and collaborative teams who are eager to learn, teach, and constantly improve how things work. Together, we strive to build robust and scalable systems that enable Brex to grow rapidly and help our customers reach their full potential.

What you’ll do

As a Security Operations Engineer at Brex, you will focus on preventing, detecting, and responding to security threats across Brex's corporate and cloud environments. You will use existing systems and develop tools to improve our security capabilities. Our team is responsible for functions across corporate security, detection & response, and infrastructure security domains, and we perform systems engineering and automation to support those functions. 

Security Operations is part of our wider Trust & IT organization, which means you will have the opportunity to work closely with Application Security, Corporate Engineering, GRC, and IT to improve security configurations, drive positive employee behaviors, and generally work to prevent events from becoming incidents. You will also help build and maintain our team’s open-source project Substation and have the opportunity to contribute to the Brex Tech Blog. You will be part of a team that actively contributes to the wider security community and has a commitment to mentorship and engineering excellence.

We are looking for individuals with a strong background and interest in detecting, responding to, and resolving security incidents and security challenges. You should be comfortable dealing with lots of moving pieces, changing priorities, and new technologies, while having a keen eye for detail. Most importantly, you should be enthusiastic about working with a variety of backgrounds, roles, and people across Brex. Building a world-class financial service requires world-class security.

Responsibilities

  • Work on a highly cross-functional team to prevent, detect, and respond to security threats across Brex's corporate and cloud environments
  • Perform security incident response, investigation, remediation, and documentation; participate in periodic threat hunting and security exercises
  • Lead the scoping and building of features, and participate in designing and maintaining tools and systems that support the team’s domains: corporate security, detection & response, and infrastructure security
  • Collaborate and partner with Engineering and Operations teams to drive remediation of security issues, while balancing prioritization of those security issues within SLA and teams’ respective backlogs
  • Care about secure system design, value building things correctly, and practice an MVP approach and an empathetic mindset when working with others

Requirements

  • Bachelor’s degree in Computer Science, Engineering, or related field OR equivalent training / fellowship OR 3+ years of work experience
  • Experience working in a corporate security, detection & response, or infrastructure security role with responsibilities for security alert triage and security incident response 
  • Familiarity with CI/CD systems and DevOps workflows (e.g. Buildkite, Flux, Git, Terraform) in cloud environments (e.g. AWS, Azure, GCP)
  • Experience with deploying and maintaining some of the security services and tools owned by the team (e.g. SIEM, data pipelines, SOAR, domain monitoring, endpoint tooling, email protection tooling, cloud security tools)
  • While not primarily a development role, the team develops and maintains tools written in Go and Python, so experience with coding is required
  • You thrive in a collaborative environment filled with a diverse group of people with different expertise and backgrounds (we currently have around 30 nationalities represented with more than ½ the company working in a country different from the one they grew up in)
  • English proficiency/fluency, both written and speaking (note: interviews will be conducted in English)

Bonus points

  • Proficiency with Go and other programming languages 
  • Experience with securing distributed systems in AWS, cloud, and Kubernetes environments
  • Contributions to the wider technical community (open source, public research, mentorship, community organizing, blogging, presentations, etc.)

Location

  • Must be working in Brazil at the start of role
