Strategic Oversight: Lead the maintenance and scalability of test, development, and operational environments, collaborating with Network and DevSecOps teams to enhance resilience.
Multi-Tier Support: Deliver Tier 1–3 maintenance and incident response for the full cybersecurity portfolio (ACAS, Trellix, Splunk, XSOAR).
