Cloud Security Admin

The Cloud Security (Wiz Admin) is responsible for administering, operating, and optimising Aviva's Wiz Cloud Security Posture Management (CSPM/CNAPP) platform.

The administrator will drive operational excellence, support engineering teams, integrate Wiz into enterprise tooling, and maintain policy compliance and posture improvement., Platform Administration & Operations

• Own day-to-day administration of the Wiz platform across all cloud environments.
• Maintain Wiz connectors, least-privilege roles, integration points, and scanning configurations.
• Ensure onboarding/offboarding of cloud accounts, subscriptions, and K8s clusters.
• Monitor platform health, ingestion coverage, API integrations, and license utilisation.

Cloud Posture Management

• Review, tune, and maintain security policies, controls, and baselines (e.g., CIS, NIST, ISO).
• Validate and enhance attack path analysis, identity risk detection, and data exposure mapping.
• Prioritise findings using impact-based and exploit-path-based logic.
• Partner with Cloud Platform teams to ensure guardrails remain aligned with Wiz detections.

Shift-Left Enablement

• Work with DevOps/SRE teams to embed Wiz in CI/CD pipelines for IaC scanning.
• Run onboarding sessions for teams on using Wiz Issues, Projects, and Policy-as-Code.
• Validate false positives/negatives and fine-tune policy gates for Terraform, ARM/Bicep, and CloudFormation.

Incident & Risk Handling

• Support Cloud Security, SOC, and IR teams during investigations involving publicly exposed, exploitable, or high-risk cloud assets.
• Provide expert analysis on Wiz findings and attack paths; propose remediation and compensating controls.
• Contribute to post-incident reviews, root-cause analysis, and long-term posture improvements.

Integrations & Automation

• Maintain integrations with Jira/ADO, SIEM/SOAR, Slack/Teams, and CMDB/GRC.
• Automate workflows for enrichment, prioritisation, ticketing, and reporting.
• Partner with Engineering to build auto-remediation playbooks for safe-to-fix classes (e.g., public S3, permissive IAM).

Governance, Reporting & Compliance

• Produce monthly security posture reports for leadership and Risk/Compliance teams.
• Track KPIs (coverage, MTTR, SLA adherence, risk trends).
• Support external and internal audit requests using Wiz's evidence and compliance modules.Manage exceptions/waivers and ensure they are reviewed and retired on schedule.

Do you have experience in Terraform?, * Strong understanding of AWS, Azure, and GCP security controls and architecture.

• Hands-on experience with cloud IAM, network security, logging/monitoring, and workload security.
• Familiarity with Kubernetes security and container image scanning.
• Experience operating cloud security platforms (Wiz preferred; alternatives: Prisma, Lacework, Defender for Cloud).
• Working knowledge of Infrastructure-as-Code (Terraform strongly preferred).
• Understanding of identity and entitlements management (CIEM).
• Ability to analyse cloud attack paths and map misconfigurations to real exploitable risk.

Nice-to-Have Skills Required:

• Experience integrating security tools into CI/CD pipelines (Azure DevOps, GitHub, GitLab).
• Knowledge of SAST/DAST/Secret scanning tools.Exposure to SRE or Cloud Platform engineering.
