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.

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.
