• Proven experience in data center migrations, consolidations, and refresh initiatives.
• Expertise in network automation and orchestration using Python, Ansible, REST APIs, or similar tools.
• Skilled in network troubleshooting, performance tuning, and packet analysis (NX-OS, Wireshark, telemetry tools).
• Thorough understanding of high availability design principles, QoS, and traffic engineering.
• Experience in change control, incident management, and infrastructure documentation practices.

Good To Have

• Working knowledge of Palo Alto Firewalls (policy management, threat prevention, HA configurations).
• Experience with F5 Load Balancers (VIP setup, SSL offloading, iRules, GSLB, LTM/ASM modules).
• Exposure to Infoblox IPAM/DNS/DHCP administration.
• Familiarity with network monitoring and observability tools (SolarWinds, Splunk, ThousandEyes, NetBrain, etc.).
• Understanding hybrid/multi-cloud networking (AWS, Azure, GCP) and cloud connectivity patterns.
• Relevant certifications preferred: CCNP/CCIE Data Center, CCNP Enterprise, or DevNet Professional.
• Experience implementing security and compliance frameworks relevant to financial services.

Process Skills:

• Proficiency in ITIL-based operational processes - Incident, Problem, Change, and Configuration Management.
• Ability to develop and maintain standard operating procedures (SOPs), runbooks, and technical documentation.
• Experience with project delivery methodologies and stakeholder communication during large-scale implementations.
• Ensure adherence to governance, compliance, and audit requirements.
• Conduct technical design reviews, risk assessments, and post-implementation validation.
• Behavioral Skills:
• Strong analytical thinking and problem-solving ability in complex technical environments.
