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.
