• Perform regular scanning and analysis for vulnerabilities across cloud, network, and infrastructure environments, prioritizing remediation and validating risk reductions.
• Enforce strong security controls across AWS, Azure, and Quorum’s hybrid cloud infrastructure, including secure configuration, IAM, network segmentation, encryption in transit and at rest, and continuous logging and monitoring.
• Collaborate with IT, CloudOps, and Engineering teams to ensure secure configurations and hardened operations of servers, endpoints, applications, and network components.
• Support audits and compliance programs (SOC 2, ISO 27001, GDPR, CPRA) by preparing documentation, evidence, and assisting with control validation.

• Stay current on emerging threats, vulnerabilities, and technologies, applying relevant intelligence to proactively improve detection and prevention capabilities.
• Contribute to risk assessment and mitigation activities, ensuring that security controls align with business priorities and threat landscape evolution.
• Perform other duties as assigned to support the mission of maintaining Quorum’s secure and resilient operations.
