About the Role

We are seeking highly skilled and motivated Senior Network Reliability Engineers (Sr. NRE) to join our Core Network Engineering & Operations team in Hyderabad. In this role, you will be responsible for ensuring the reliability, scalability, performance, and automation of our next-generation cloud datacenter network infrastructure.

You will work closely with architecture, software, and product teams to operate, monitor, troubleshoot, and automate large-scale IP/MPLS and Clos-based datacenter networks powering enterprise-grade IT products and cloud platforms.

Key ResponsibilitiesCapable of working under limited supervision and driving complex technical resolutions independently

Technical Leadership

• Apply professional concepts and company strategic objectives to resolve complex, unstructured technical issues in creative, efficient ways.
• Demonstrate excellent judgment in influencing network product roadmap direction, feature requirements, and strategic priorities.
• Work independently with minimal supervision, providing technical mentorship to junior team members.

Network Operations & Incident Management

• Operate, monitor, and troubleshoot large-scale network infrastructure in a high-availability Datacenter, ISP, or Cloud hosting environment.
• Perform rapid incident diagnosis and resolution for complex network performance degradation or outages.
• Participate in on-call rotations and work flexible shifts to maintain 24/7/365 network operational reliability.

Datacenter & Network Architecture

• Demonstrate a deep understanding of Data Center builds, spine-and-leaf design, and CLOS architecture.
• Maintain, optimize, and assist in designing robust routing and switching architectures across hybrid/cloud networks.

Protocol Mastery & Traffic Engineering

• Deep technical expertise and hands-on operational knowledge of key network protocols: MPLS, BGP, IPv6, DNS, DHCP, and SSL.
• Advanced working experience with VxLAN and EVPN technologies (added advantage).

Network Telemetry, Monitoring & Observability

• Design, implement, and maintain modern network monitoring and telemetry solutions.
• Hands-on experience with telemetry stacks such as Prometheus, Grafana, and related network observability software.

Automation & Scripting

• Drive network-as-code initiatives with strong, hands-on automation experience using Python (and related network automation frameworks/tools).
• Automate routine network operational tasks, telemetry generation, and remediation scripts.
