Leads moderately complex projects, drives automation design discussions, and contributes to design and architecture improvements. Mentors junior engineers, provides input on team decisions, and collaborates with SRE, platform, and security partners to deliver secure, compliant, and highly available network services with measurable impact on both team and group outcomes.\n Key Responsibilities\nL3/L4 Network Topologies and Overlays:\nLead designs for IP addressing, routing policies (BGP/OSPF/IS-IS), EVPN/VXLAN fabrics, and SDN overlays spanning on-prem and cloud.\nDefine HA, ECMP, and traffic-engineering patterns; validate through lab/sandbox testing, failure modeling, and staged rollouts.\nAuthor design docs and drive reviews involving related teams; de-risk changes with method-of-procedure (MOP), rollback, and verification plans.\nCloud Networking Implementation and Operations:\nImplement and operate VPC/VNet topologies, subnets, routing tables, NAT, Transit/Hub-and-Spoke (e.g., TGW/VCN), PrivateLink/service endpoints, and inter-cloud connectivity.\nDesign and tune L4/L7 load balancing and service insertion (proxies, firewalls) to meet defined SLOs and cost targets.\nEnsure consistent network policy and connectivity across environments using standard blueprints and golden configs.\nNetwork Security Controls and Compliance Guardrails:\nEngineer segmentation (VRFs/security zones), ACLs/policies, encryption (IPsec/TLS), and DDoS/WAF integrations aligned to zero-trust.\nEmbed compliance guardrails (change control, access least privilege, evidence collection) and partner with security/GRC to pass audits.\nPeriodically review rulebases and routing policies; eliminate shadow/duplicate rules and reduce attack surface.\nAutomation, CI/CD, and Infrastructure as Code:\nDevelop reusable Terraform modules and Ansible playbooks; enforce code reviews, linting, policy-as-code, and test gates in pipelines.\nBuild validation and drift-detection tooling using APIs and scripting (e.g., Python); integrate automated rollbacks and canary changes.\nChampion GitOps practices, configuration data modeling, and inventory source of truth.\nCross-Team Collaboration and Operations Excellence:\nPartner with SRE, platform, and security teams on architecture reviews, incident response, post-incident remediation, and capacity planning.\nLead portions of on-call response and complex change events; coordinate with related teams to minimize risk and downtime.\nContribute to cross-LOB standards, reference architectures, and service onboarding patterns.\nDocumentation, Reviews, and Standards:\nProduce and maintain high-quality design docs, network diagrams, runbooks, and inventories; ensure traceability to requirements and controls.\nFacilitate and participate in design/change reviews; capture decisions and lessons learned; evolve patterns and modules accordingly.\nMentor junior engineers via code/document reviews, pairing, and knowledge shares.\nJob Qualifications\nNetwork Engineering Expertise & Experience:\nCore networking: Advanced knowledge of L2/L3/L4, IP addressing/subnetting, BGP/OSPF/IS-IS, EVPN/VXLAN, ECMP, QoS, NAT; strong DNS/DHCP fundamentals; IPv6 design and transition patterns.\nCloud networking: Proficiency with VPC/VNet, route tables, NAT gateways, PrivateLink/service endpoints, transit/peering, hybrid and inter-cloud connectivity; L4/L7 load balancing and service insertion.\nSecurity and compliance: Zero-trust segmentation, ACLs/policies, IPsec/TLS, DDoS/WAF patterns; familiarity with audit frameworks and evidence practices; change/access control rigor.\nAutomation and IaC: Terraform and Ansible at module/playbook level; Git and CI/CD; scripting (e.g., Python); API-driven platforms; policy-as-code, unit/integration testing, and automated validation.\nObservability: Designing and operationalizing SNMP/telemetry, NetFlow/IPFIX, flow logs; SLI/SLO definition; capacity modeling and performance tuning.\nOperations: Seasoned in incident management, on-call, RCAs, and structured change management; able to lead complex maintenance events.\nCollaboration and communication: Clear technical writing, effective reviews, and the ability to influence related teams; comfort presenting trade-offs to stakeholders.\nProblem solving and innovation: Uses judgment on multi-variable problems; leads small-scale innovation/improvement initiatives; evaluates alternatives and fallout to ensure safe adoption.\nEducation and/or Experience:\n11 years of experience in Network Engineering or related field\nOR\nBachelor's of Technology (B.Tech) Degree/Bachelor's Degree in Computer Science, Computer Engineering, Software Engineering, Electrical/Electronics Engineering, Mechnical Engineering, Computer Information Systems, Information Systems, Information Technology, Telecommunications, Mathematics, Physics, or related field AND 7 years of experience in network Engineering\nOR\nMaster's of Technology (M.Tech) Degree/Master's Degree in Computer Science, Computer Engineering, Software Engineering, Electrical/Electronics Engineering, Mechnical Engineering, Computer Information Systems, Information Systems, Information Technology, Telecommunications, Mathematics, Physics, or related field AND 5 year of experience in nework engineering or related field.\nOR\nDoctorate in Computer Science, Computer Engineering, Software Engineering, Electrical/Electronics Engineering, Mechnical Engineering, Computer Information Systems, Information Systems, Information Technology, Telecommunications, Mathematics, Physics, or related field and 3 years of experience in nework engineering or related field.\nPreferred Job Qualifications\nEducation and/or Experience:\n11 years of experience in Network Engineering or related field\nOR\nBachelor's of Technology (B.Tech) Degree/Bachelor's Degree in Computer Science, Computer Engineering, Software Engineering, Electrical/Electronics Engineering, Mechnical Engineering, Computer Information Systems, Information Systems, Information Technology, Telecommunications, Mathematics, Physics, or related field AND 7 years of experience in network Engineering\nOR\nMaster's of Technology (M.Tech) Degree/Master's Degree in Computer Science, Computer Engineering, Software Engineering, Electrical/Electronics Engineering, Mechnical Engineering, Computer Information Systems, Information Systems, Information Technology, Telecommunications, Mathematics, Physics, or related field AND 5 year of experience in nework engineering or related field.\nOR\nDoctorate in Computer Science, Computer Engineering, Software Engineering, Electrical/Electronics Engineering, Mechnical Engineering, Computer Information Systems, Information Systems, Information Technology, Telecommunications, Mathematics, Physics, or related field and 3 years of experience in nework engineering or related field.\nDisclaimer:Certain U.S. based or U.S. customer or client-facing roles may be required to comply with applicable requirements, such as immunization/occupational health mandates, and/or drug testing requirements.\nRange and benefit information provided in this posting are specific to the stated locations only\nUS: Hiring Range in USD from: $114,600 to $234,600 per annum.
