Key Responsibilities 

• Implement and support large scale DNS Architecture that stretches private & public cloud across multiple regions.
• Implement and support Infoblox DDI solutions (DNS, IPAM, DHCP), Cloudflare DNS management, Google & AWS DNS services.
• Implement and support highly reliable NTP and LDAP services on Linux instances.
• Implement Infrastructure as code leveraging CI/CD automation, Ansible, Terraform/Pulumi, Python and Bash for automated provisioning of DNS services.
• Be involved in Change management and Global team collaboration
• Implement continuous delivery pipelines for Infrastructure updates, including patch management, service upgrade testing, and rollback procedures.
• Develop automated monitoring, alerting, and healing mechanisms using GitOps principles and observability stacks (e.g., Prometheus, Loki, Grafana).
• Harden services for high availability, disaster recovery, and scale-out operations.
• Perform deep-dive troubleshooting and performance analysis of Infrastructure services across hypervisors, backend storage protocols and networking layers.
• Participate in on-call rotation, incident response, and root cause analysis for platform reliability issues.

Minimum Qualifications 

• 5+ in managing global DNS, NTP and LDAP systems on Linux Operating Systems.

• Working experience implementing OpenLDAP & NTP services (preferably Microchip SyncServer systems).
• Strong Linux (RHEL/CentOS/Ubuntu) systems engineering background with advanced scripting in Python, Bash, or Go.
• Familiar with Cisco UCS Blade Servers (or similar server Infrastructure), Block/File Storage (Soft defined storage preferred).
• Fluency with Git, CI/CD pipelines, and automated test frameworks.
• Familiar with various Infrastructure technology stacks like Hypervisor Technologies (KVM, Vsphere,), storage protocols (SDS) (iSCSI, NFS, CEPH), L2/L3 Networking
• Strong experience supporting mission critical 24x7 customer facing production environments.
• Demonstrated success building or maintaining multi-region or high-availability OpenStack clusters.
• Ability to write technical documentation and contribute to community wikis or knowledge bases.

Preferred Qualifications 

• Good understanding of overall Enterprise Common Infrastructure service implementations with focus on DNS, NTP & LDAP.
• Understanding of security best practices for system patching and security compliance (e.g., CIS, NIST).
• Background in telco, edge cloud, or large enterprise infrastructure environments.
• Experience building and maintaining automated test environments for system upgrades and DNS migrations.
• Bachelor’s degree in computer science, IT, Engineering, or a related field preferred; equivalent experience and relevant industry certifications will also be considered
