7. Provide technical input into infrastructure monitoring and alerting standards, collaborating with operational teams to ensure system health, reliability, and availability requirements are effectively represented.

8. Act as a senior escalation resource during infrastructure incidents, assisting with troubleshooting, service restoration, and follow-up analysis to reduce recurrence and improve reliability.

9. Provide technical guidance and mentorship to infrastructure and operations staff, promoting standardization, sound engineering practices, and effective operational procedures.

10. Design, support, and improve core enterprise services including DNS, DHCP, IP address management, time synchronization, and certificate management.

11. Participate in datacenter infrastructure operations, including system lifecycle planning, capacity management, and execution of infrastructure changes.

12. Maintain and support server platforms through lifecycle activities including performance analysis, capacity tuning, patch management, and remediation of stability or reliability issues.

13. Assist with vendor and service provider engagements, including technical reviews, service coordination, and operational escalation for critical infrastructure services such as connectivity and hosting.

14. Produce and maintain documentation for system designs, operational procedures, recovery processes, and normal operating conditions to support sustainable operations.

15. Assume primary responsibility for the technical definition and evaluation of infrastructure initiatives, ensuring designs appropriately address reliability requirements, operational risk, and cost effectiveness.

16. Perform deep technical investigation of complex or emergent infrastructure issues when initial analysis is insufficient, applying expert diagnostic methods to identify root causes and guide effective resolution.

17. Remain current with evolving infrastructure, automation, and cloud technologies, applying improvements where appropriate to enhance stability and efficiency.

18. Interact professionally and effectively with internal partners, customers, and stakeholders, encouraging strong operational relationships.

REQUIRED KNOWLEDGE, SKILLS AND ABILITIES (KSA's):

1. Bachelor's degree in Information Systems, Computer Science, Engineering, or a related field preferred, or an equivalent combination of education and 10 or more years of experience in infrastructure or systems engineering roles.
