Operations Leadership and Service Reliability

• Provide technical leadership to multi-discipline server and system operations teams in enterprise environments.

• Establish architecture requirements for monitoring, alerting, incident response, and operational visibility for production systems.

• Support root-cause analysis, corrective actions, and continuous improvement efforts tied to SLA and performance objectives.

• Ensure designs are supportable in 24x7x365 operations, including change/release coordination and lifecycle management.

Security, Compliance, and Integration Governance

• Provide technical leadership for system integration, scalability, and security architecture across multi-vendor platforms.

• Embed security controls and compliance requirements into infrastructure and platform designs.

• Ensure architectural approaches support FISMA-aligned controls, vulnerability remediation, and secure configuration baselines.

• Collaborate with cross-functional stakeholders to align technical solutions with SEC policy, risk, and operational governance.
