Job Title: Sr Security Architect
Reports to (Direct Title): Sr. Manager, Threat Intelligence
Department: Cybersecurity Operations
Position Summary
This role secures the multi-cloud infrastructure behind Black Duck's SaaS platforms. The Sr Security Architect will work on cloud security controls from design to operation: maintaining the baseline, finding where the environment departs from it, and working with engineering and platform teams until the risk is closed. The role is hands-on in the tooling and in the code, and automates anything done more than twice. This role works with broad autonomy and carries project-level technical leadership. The role leads cloud security projects or parts of larger initiatives, act as a technical resource for less experienced team members, and communicates risk clearly to technical teams and management.
Essential Functions/Responsibilities
- Contribute to and maintain Black Duck's cloud security baseline: standards, guardrails, and reference configurations for GCP, Azure, and AWS, written so engineering teams can actually apply them.
- Design, build, and operate preventive and detective controls for SaaS workloads, including identity and access (IAM, workload identity, service accounts), network segmentation, encryption and key management, secrets handling, and logging coverage.
- Operate, tune, and enhance the cloud-native application protection platform (Wiz or comparable CNAPP): onboarding cloud accounts and Kubernetes clusters, writing and tuning policies and custom controls, cutting noise, and maturing coverage from agentless scanning to runtime sensors.
- Triage posture, vulnerability, and identity findings by real exposure and exploitability, not by raw severity, then partner with resource owners to prioritize and complete remediation, tracked against policy SLAs.
- Conduct security reviews and provide recommendations for new cloud services, architectures, and third-party integrations, using threat modeling and proofs of concept, before they reach production.
- Secure containerized and Kubernetes platforms (GKE, AKS, EKS): cluster hardening, RBAC, admission control and policy as code, image provenance, and runtime protection.
- Build security into CI/CD and infrastructure-as-code workflows (IaC scanning, image scanning, secrets detection, policy gates) so issues are caught before deployment rather than found in production.
- Contribute to software supply chain integrity for build and deployment pipelines, consistent with Black Duck's position as a software supply chain security company.
- Develop and maintain cloud detections from audit logs, control-plane events, and CNAPP signals; validate that the telemetry they depend on is actually collected.
- Support the CSIRT on cloud incidents: scoping, containment, evidence preservation, cloud forensics, and remediation, including post-incident hardening.
- Automate controls, enrichment, and remediation workflows using Python, Bash, cloud APIs, and infrastructure as code (Terraform, Helm).
- Lead defined cloud security projects and contribute to workstreams within complex cross-functional initiatives across engineering, platform, IT, and vendor partners.
- Provide technical guidance to less experienced team members, participate in peer reviews, and share cloud security best practices.
- Communicate cloud security risks and recommended actions to technical teams and management, supporting senior-level discussions as needed.
- Produce evidence and control documentation that supports SOC 2 and ISO 27001 audits and customer security reviews.
- Keep current on cloud attack techniques, provider security changes, and emerging threats, and recommend systematic improvements.
- Other tasks and activities as assigned.
Required Education/Experience & Skills
- Experience: typically 5 or more years in information security, including at least 3 years hands-on securing production cloud environments at scale.
- Cloud depth: in-depth conceptual and practical knowledge of at least one major provider (GCP, Azure, or AWS) and working fluency in a second, covering IAM models, networking, logging, and native security services. Production experience with GCP and Azure is a strong advantage.
- Kubernetes and containers: hands-on experience securing Kubernetes clusters and container workloads in production.
- CNAPP: hands-on experience with Wiz or a comparable CNAPP, especially policy development, custom controls, and runtime sensor deployment; plus cloud logging, monitoring, and vulnerability management platforms at scale.
- Automation: strong Python and/or Bash for security automation and integration; comfortable working directly with cloud provider APIs.
- Infrastructure as code: practical experience with Terraform, Helm, or equivalent, including reviewing IaC for security issues.
- Compliance: familiarity with SOC 2, ISO 27001, and FedRAMP frameworks (framework knowledge).
- Leadership: experience leading projects or parts of complex projects and building consensus across teams.
- Communication: strong written and verbal English; able to explain complex or sensitive security issues to technical and executive audiences.
- Education: Bachelor's degree in Computer Science, Information Security, or a related field, or equivalent practical experience. Relevant certifications are a plus (e.g., CKS, Google Professional Cloud Security Engineer, Microsoft Azure Security Engineer Associate, AWS Certified Security Specialty, CCSP, CISSP, or GIAC).
Physical Requirements

- Extensive use of the computer which involves viewing a monitor and keyboarding for most of the workday
- Placing and receiving phone calls
- Occasionally moving and lifting objects up to 20 pounds
- May require some travel as needed.
