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
