About The Role

Demandbase is seeking a hands-on Senior Security Engineer to join our Product Security team. In this role, you will own and advance security across our AWS, GCP, Kubernetes, containers, virtual machines, and infrastructure-as-code environments. You will evaluate real attack paths, translate cloud risk into practical engineering action, and help prevent recurring issues through secure architecture, automation, and guardrails.

You'll partner closely with Cloud Engineering, SRE, Platform, Infrastructure, Product Engineering, and Security Incident Response teams. This is an ownership-oriented role for an engineer who can independently investigate complex cloud-security problems, prioritize risk based on exploitability and business impact, drive remediation to closure, and communicate clearly with both engineers and leaders.

This position offers an opportunity to shape cloud-security engineering at scale, reduce systemic risk across a modern multi-cloud environment, mentor developing security engineers, and grow toward broader technical leadership.

What you'll be doing

Cloud Security Ownership

• Own cloud-security posture and risk reduction across AWS, GCP, Kubernetes, containers, virtual machines, and supporting infrastructure services.

• Independently investigate complex misconfigurations and attack paths, determine actual exposure, and drive issues from discovery through verified closure.

• Partner with engineering teams to design secure, scalable solutions instead of relying only on tickets or compensating controls.

Architecture and Infrastructure-as-Code

• Perform security reviews for new cloud services, infrastructure designs, network patterns, data flows, and high-risk architectural changes.

• Review Terraform and CI/CD workflows, and develop preventive controls that identify or block insecure infrastructure before deployment.

• Strengthen secure-by-default patterns for cloud accounts, projects, workloads, networking, storage, secrets, encryption, logging, and service-to-service access.

Identity and Access Management

• Evaluate AWS IAM, GCP service accounts, workload identity, federation, trust relationships, and privileged access against least-privilege principles.

• Reduce excessive permissions, long-lived credentials, dormant identities, insecure keys, privilege-escalation paths, and cross-account or cross-project trust risks.

Kubernetes, Containers, and Compute Security

• Assess Kubernetes RBAC, workload identity, admission controls, network policies, secrets handling, runtime configurations, and cluster or workload isolation.

• Drive adoption of Demandbase-owned golden images, secure base images, automated upgrades, and timely remediation of critical and high-risk operating-system and package vulnerabilities.

• Improve the health of active container images and virtual machines while prioritizing resources that create meaningful production exposure.

Risk Triage, Automation, and Metrics

• Lead risk-based triage of Wiz and other cloud-security findings; validate exploitability, identify root cause, recommend practical remediation, and eliminate avoidable noise.

• Build scripts, integrations, guardrails, dashboards, and automated remediation workflows for recurring cloud-security problems.

• Define and report outcome-oriented metrics for external exposure, IAM risks, Kubernetes issues, unhealthy VMs and container images, remediation aging, and recurrence.

Incident Support and Technical Leadership

• Support cloud incident investigations with attack-path analysis, evidence collection, blast-radius assessment, containment guidance, and durable corrective controls.

• Represent Product Security in technical discussions and risk escalations, influence teams without direct authority, and communicate trade-offs clearly.

• Mentor security and engineering team members, document reusable patterns, and help develop reliable secondary owners for cloud-security domains.

What we're looking for

• 5+ years of experience in security, infrastructure, platform engineering, or a related technical field, including 4+ years of hands-on cloud-security experience.

• Deep practical knowledge of AWS/GCP in production environments.

• Strong knowledge of Kubernetes, containers, Linux, virtual machines, cloud networking, storage, secrets management, encryption, and logging.

• Hands-on expertise in cloud IAM, including AWS IAM, GCP service accounts, workload identity, federation, policy evaluation, and least-privilege design.

• Experience reviewing or developing Terraform and integrating security controls into CI/CD workflows.

• Experience using a CSPM platform such as Wiz to investigate and prioritize risk; the ability to go beyond tool output and validate technical impact is essential.

• Ability to automate security workflows using Python, Go, APIs, or similar technologies.

• Strong understanding of cloud attack techniques, privilege escalation, lateral movement, internet exposure, data exfiltration, and workload isolation.

• Demonstrated ability to own ambiguous problems, work independently, and drive cross-functional remediation to measurable completion.

• Excellent written and verbal English communication skills, including the ability to explain technical risk and remediation to engineers and leaders.

• Experience mentoring engineers or leading technical initiatives across multiple teams is strongly preferred.

• Relevant certifications such as AWS Certified Security - Specialty, Google Professional Cloud Security Engineer, CKS, CISSP, or equivalent practical experience are desirable.
