Sr Security Engineer - 11806

The Impact of a Senior Security Engineer at Coupa

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

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'll Bring to Coupa:

• 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
