Sr Security Engineer

Coupa's Security Engineers keep our enterprise, product, platform, and customer data safe. As a Senior Security Engineer, you'll take ownership of complex, ambiguous security problems end to end — building cloud security controls, setting engineering standards, and partnering closely with Engineering, IT, and Compliance to ship durable, automated security tooling rather than one-off fixes. You'll set the technical standard for how the team remediates and automates, and you'll be a go-to resource other engineers turn to when a finding needs real root-cause analysis instead of a quick workaround.

* Design and implement multi-cloud security controls across Coupa's cloud environment, including VPC segmentation, security groups/NACLs, IAM policy design using least-privilege and permission boundaries, and Organizations/SCPs for guardrails at scale. * Build policy as code and IaC security guardrails and wire them into CI/CD as pre-merge and pre-deploy gates rather than after-the-fact reviews. * Harden containerized workloads and Kubernetes clusters — image scanning, admission control, pod security standards, network policies, and container/workload runtime detection. * Own vulnerability analysis of application packages, container images, and third-party dependencies; triage findings by exploitability and business impact rather than CVSS score alone. * Design and implement remediations — not just report findings — including secure code fixes, cloud configuration changes, and IAM policy adjustments using least-privilege principles. * Support incident response and forensics as a technical contributor — log analysis, root-cause investigation, and remediation validation using cloud-native and EDR tooling. * Partner with the Risk & Compliance team to provide technical evidence and control validation for audit frameworks (SOC 2, ISO 27001, PCI-DSS, FedRAMP). * Support and mentor other security engineers — reviewing designs and remediation plans, sharing root-cause analysis techniques, and helping less experienced teammates work through complex or ambiguous findings. * Participate in the on-call/incident rotation and help continuously improve remediation and response runbooks.

* 7+ years of experience in security engineering or penetration testing, with a track record of independently owning complex assessments from scoping through remediation. * Practical experience with cloud security fundamentals (AWS, GCP, or Azure) — IAM, networking, and common misconfiguration classes — sufficient to both find and fix cloud findings. * Strong scripting/automation skills in Python, Bash, or JavaScript, with experience building or extending internal security tooling. * Experience with dependency/container vulnerability scanning tools and integrating them into CI/CD pipelines. * Working knowledge of common compliance frameworks (SOC 2, ISO 27001, PCI-DSS, FedRAMP) and what auditable evidence looks like. * Critical thinking and root-cause analysis skills — comfortable digging past a scanner's output to understand and explain why a vulnerability exists. * Clear written and verbal communication skills for translating technical findings into remediation guidance for engineers and risk context for stakeholders. * Bachelor's degree in Computer Science, Information Systems, or a related field, or equivalent practical experience. * Relevant certifications a plus: CISSP, CCSP, CISA, or AWS/GCP security certifications
