We are seeking a highly experienced Senior Network Engineer to support the stability, performance, and security of enterprise and data center network infrastructure. This role requires deep, hands-on expertise in complex routing environments, with a strong focus on BGP (Border Gateway Protocol) and OSPF (Open Shortest Path First) design, deployment, and troubleshooting.

Important: Candidates must demonstrate proven, real-world experience managing and optimizing large-scale routing environments. Profiles with only theoretical knowledge or limited exposure will not be considered.

Key Responsibilities

• Design, implement, and maintain internal and external network infrastructure supporting critical business applications
• Manage and support Cisco-based environments, including Catalyst and Nexus platforms, wireless networks, ISE, and IPS
• Perform advanced routing and switching troubleshooting, including production issue resolution
• Develop and implement network designs to improve performance, resiliency, and scalability
• Plan and execute network upgrades and migrations in coordination with cross-functional teams
• Proactively monitor and analyze network health using enterprise monitoring tools
• Support data center and hybrid/cloud networking initiatives
• Ensure high availability, security compliance, and continuous network operations

Required Qualifications

• 10+ years of hands-on experience supporting enterprise-grade network infrastructure in large data center environments
• Expert-level knowledge of BGP and OSPF, including:
• Traffic engineering

•

• Route optimization

•

• Failover and convergence design

•

• Advanced expertise in TCP/IP troubleshooting and packet analysis
• Strong hands-on experience with:
• Cisco NX-OS and IOS-XE platforms

•

• Cisco Nexus (9K, 7K) and Catalyst switches/routers

•

• BGP, OSPF, and STP configuration and troubleshooting

•

• Proven experience in designing, planning, testing, implementing, and supporting large-scale data center networks
• Experience with network monitoring and management tools such as SolarWinds and Cisco Catalyst Center
• Exposure to cloud networking and hybrid architectures

Required Experience (Must Demonstrate)

Candidates must be able to clearly articulate and provide real-world examples of:

• Designing and implementing BGP and/or OSPF routing architectures in production environments
• Troubleshooting complex routing issues impacting business-critical systems
• Leading or supporting data center network deployments, upgrades, or migrations
• Implementing failover strategies, convergence tuning, and traffic optimization in large-scale networks

What Were Looking For

• Engineers with deep, hands-on routing expertise, not just keyword familiarity
• Strong problem-solvers who have worked in complex, high-availability environments
• Candidates who can confidently discuss real production scenarios and outcomes
