- Prepare and present PSA and ARB submissions and ensure proper service acceptance validation.

- Support client migrations from legacy environments (Allen, McKinney) to Equinix Extranet setups and bring non-standard builds to EEC standards.

- Manage SSL certificate renewals on NetScaler and F5 load balancers, automating renewals where possible.

- Plan and run redundancy and failover testing to validate resiliency across on-premises and cloud environments.

- Lead legacy environment clean-up to streamline infrastructure and support Cloud9 migration and hardware retirement.

- Mentor mid-level engineers, review their changes and promote network automation and best practices.
