Sr Security Engineer - 11917

The Impact of a Lead Security Engineer at Coupa:

Coupa's Security Engineering team protects our enterprise, product, platform, and customer data at scale. As Lead Security Engineer, you will be a hands-on technical leader on the Security Engineering team - architecting and 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 thrive on ambiguity, sweat the implementation details, and take pride in solutions that scale across hundreds of accounts and services.

What You’ll Do

• Architect and build multi cloud security controls across Coupa's cloud environment. 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 - image scanning, admission control, pod security standards, and runtime detection.
• Write auto-remediation for cloud misconfiguration and drift so common findings close without manual ticket routing.
• Own Vulnerability management program, act as the technical escalation point for security incidents and vulnerability findings - leading forensics, containment, and root-cause analysis using cloud-native and EDR tooling, and driving remediation to closure.
• Partner with Risk & Compliance to translate audit framework requirements (SOC 2, ISO 27001, PCI-DSS, FedRAMP) into concrete technical controls, and automate evidence collection by integrating cloud telemetry with GRC tooling.
• Mentor other security engineers through design review, threat modeling, and code/architecture review; raise the technical bar for the whole team.
• Own reference architectures, threat models, and runbooks for the security tooling you build; participate in and help improve the on-call rotation.

What You Will Bring to Coupa

• 10+ years of security engineering experience, including significant hands-on work securing production cloud environments at scale, plus experience leading projects or mentoring other engineers.
• Deep, hands-on AWS security expertise - IAM, VPC/networking, KMS, GuardDuty, Security Hub, Config, and Organizations/SCPs; working knowledge of GCP or Azure security is a plus.
• Production experience with Terraform (or equivalent IaC) and policy-as-code frameworks, plus container/Kubernetes security tooling.
• Strong software engineering fundamentals - Python and/or Go, Git-based workflows, and building/maintaining CI/CD security integrations (SAST, DAST, SCA).
• Experience with SIEM/SOAR platforms and vulnerability management tooling (e.g., Wiz, Qualys, Tenable) - building detections and workflows, not just consuming dashboards.
• Working knowledge of compliance frameworks (SOC 2, ISO 27001, PCI-DSS, FedRAMP, NIST 800-53) sufficient to translate control requirements into engineering work.
• Excellent written and verbal communication skills - able to write clear technical design docs and explain risk trade-offs to auditors and engineering leadership alike.
• 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.
• Some international travel may be required.
