Sr Security Engineer - 11816

What You'll Do:

• 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.

What You Will Bring to Coupa:

5+ years of experience in security engineering or cloud operations, 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.
