Senior Security Engineer, Enterprise Security

At Braze, we have found our people. We’re a genuinely approachable, exceptionally kind, and intensely passionate crew.

We seek to ignite that passion by setting high standards, championing teamwork, and creating work-life harmony as we collectively navigate rapid growth on a global scale while striving for greater equity and opportunity – inside and outside our organization.

To flourish here, you must be prepared to set a high bar for yourself and those around you. There is always a way to contribute: Acting with autonomy, having accountability and being open to new perspectives are essential to our continued success.

Our deep curiosity to learn and our eagerness to share diverse passions with others gives us balance and injects a one-of-a-kind vibrancy into our culture.

If you are driven to solve exhilarating challenges and have a bias toward action in the face of change, you will be empowered to make a real impact here, with a sharp and passionate team at your back. If Braze sounds like a place where you can thrive, we can’t wait to meet you.

As a Senior Security Engineer on the Enterprise Security team, you'll protect Braze employees, their devices, and our work locations. You'll investigate malware and advanced threats, secure our SaaS applications, harden internal configurations, propose security architecture improvements, and build the alerts and reports that keep the team ahead of risk.

You'll own core security infrastructure that sits at the center of Enterprise Security operations and works closely with Cloud Security, App Security, and Information Technology. That means developing and enforcing policies, expanding our SIEM capabilities with partners across the business, and evaluating vendor and partner technologies for security gaps.

Your day-to-day spans threat and malware investigations, SaaS security, AI security, architecture review, MDM, communications management, and vulnerability remediation. You'll secure communications, support compliance efforts, and automate wherever it reduces toil. You'll work both independently and cross-functionally, and you'll mentor junior engineers on security fundamentals. You’ll have the opportunity to implement DLP where needed as well as secure AI as it develops and is used to drive business function.

As a senior team member, you'll help build functionality for a high-scale, growing customer base, collaborate with diverse security professionals, address unique security challenges, participate in on-call rotations, and respond to critical incidents.
