This role is critical for protecting the organization’s digital assets and infrastructure through advanced SOC operations, analytics, automation, and AI-driven capabilities. It involves developing and implementing cybersecurity processes — with a specific focus on enabling threat response teams (SOC and CIRT)— alongside strategies that comply with organizational goals, regulatory requirements, and SOC maturity objectives. The role leads a team of cybersecurity professionals focused on equipping and enabling threat response teams to monitor, detect, and respond to cyber incidents more effectively, rather than performing those functions directly. Success is measured by the consistent delivery of processes, analytics, automation, and AI capabilities that result in improved effectiveness of security operations across threat response teams. The work ensures the operational resilience and security of information systems, and the manager participates in an on-call rotation to provide incident response leadership as needed.
