Senior Security Engineer II

Senior Security Engineer II Atlanta 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. Braze is a modern, cloud-first SaaS company running entirely on cloud-native infrastructure — large-scale, distributed systems spanning AWS, GCP, and self-managed Kubernetes, backed by self-managed data stores such as MongoDB. We're looking for a Senior Cloud Security Engineer II to join our Security Engineering function as a senior individual contributor and technical leader for cloud security. This is a step up from our Senior Cloud Security Engineer role. Where a Senior engineer executes and improves our cloud security controls, a Senior Cloud Security Engineer II sets the technical direction: you define the standards and reference patterns other engineers build on, lead cross-team security initiatives end to end, take on the ambiguous problems that don't yet have a playbook (and write the playbook), and raise the bar for the whole team through mentorship and review. You'll go especially deep across three areas — secure architecture and threat modeling, detection engineering and incident response, and Kubernetes and platform security — and you'll shape how Braze does cloud security across Engineering. This is a pure IC role; you lead through technical depth and influence rather than direct people management. What You'll Do Set the technical direction (leadership & standards): Define the cloud security standards, guardrails, and reference architectures that Infrastructure, SRE, and Product Engineering build on — turning point-in-time fixes into durable, org-wide patterns Set your own objectives and roadmap for high-impact cloud security work, in partnership with Security Engineering leadership, and drive it to measurable outcomes Lead cross-functional security initiatives end to end — scope, timeline, stakeholders, and delivery — guiding technical debates to a decision and owning the result Mentor and uplevel other security and platform engineers through pairing, design review, and feedback; act as a force multiplier and the go-to technical resource for cloud security Represent cloud security in architecture and design forums, translating complex attack paths and risk into clear, actionable guidance engineers will actually adopt Secure architecture & threat modeling: Own threat modeling as a discipline for new cloud technologies, services, and patterns adopted across Engineering — making it a repeatable, scalable practice rather than a one-off exercise Partner with Infrastructure, SRE, and Product Engineering to design secure-by-default cloud architectures and build practical, scalable controls across AWS, GCP, and self-managed systems Drive control-plane and IAM security strategy across AWS and GCP, including relationships with external identity providers, RBAC models, and least privilege at scale Continually assess posture, surface systemic and emerging risk, and set the priorities that reduce it Detection engineering, incident response & automation: Advance our detection strategy: design high-signal detections and SIEM rules (with our SIEM Management function) and own detection coverage for cloud threats end to end Serve as a senior incident responder and cloud-forensics lead for cloud and run-time security investigations across AWS and GCP — and codify what you learn into standard IR playbooks and preventative controls Own and optimize security tooling such as CrowdStrike (EDR/CSPM/IR), Tenable, and native cloud security services, and lead our vulnerability management workflow — scanning, triage, prioritization, and remediation — for cloud assets Kubernetes & platform security: Own the security of our self-managed Kubernetes environments — control plane, nodes, workload isolation, admission control, run-time security, and the CI/CD supply chain feeding them Set the standards for Infrastructure-as-Code and pipeline security (Terraform preferred): design and harden IaC and CI/CD automation so security is built into how we ship Establish best practices for patch management, base-image hardening, and version management across containerized and VM-based environments Lead the security of large-scale, distributed systems and self-managed data stores (e.g., MongoDB), accounting for their real-world operational and security implications Who You Are You are a senior individual contributor who leads through technical depth and influence rather than authority. You can take an ambiguous, open-ended cloud security problem, define the objective yourself, and deliver a solution that becomes the way Braze does it going forward. You translate complex cloud attack paths, IAM misconfigurations, and multi-step threat scenarios into guidance engineers adopt, and you balance strong controls with operational reality. You raise the people around you — through mentorship, review, and the standards you set — and you stay current with the cloud security landscape, tools, and threats. Above all, you can walk someone through the messy middle — what you tried, what broke, and what you'd do differently. The Few Hard Prerequisites: These are the genuinely pass/fail requirements: Several years owning cloud security in production — on-call for it, not adjacent to it Hands-on, not theoretical: AWS as primary cloud, working GCP, self-managed Kubernetes You read and write code (Python, TF) What We Offer Braze benefits vary by location, and we encourage you to review our specific benefits offerings for each country here.
