Job description

Job Description

Designs, implements, and operates resilient L3/L4 network services across data centers and cloud environments with broader influence beyond the immediate team. 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.

Responsibilities

Key Responsibilities

L3/L4 Network Topologies and Overlays

• Lead designs for IP addressing, routing policies (BGP/OSPF/IS-IS), EVPN/VXLAN fabrics, and SDN overlays spanning on-prem and cloud.
• Define HA, ECMP, and traffic-engineering patterns; validate through lab/sandbox testing, failure modeling, and staged rollouts.
• Author design docs and drive reviews involving related teams; de-risk changes with method-of-procedure (MOP), rollback, and verification plans.

Cloud Networking Implementation and Operations

• Implement and operate VPC/VNet topologies, subnets, routing tables, NAT, Transit/Hub-and-Spoke (e.g., TGW/VCN), PrivateLink/service endpoints, and inter-cloud connectivity.
• Design and tune L4/L7 load balancing and service insertion (proxies, firewalls) to meet defined SLOs and cost targets.
• Ensure consistent network policy and connectivity across environments using standard blueprints and golden configs.

Network Security Controls and Compliance Guardrails

• Engineer segmentation (VRFs/security zones), ACLs/policies, encryption (IPsec/TLS), and DDoS/WAF integrations aligned to zero-trust.
• Embed compliance guardrails (change control, access least privilege, evidence collection) and partner with security/GRC to pass audits.
• Periodically review rulebases and routing policies; eliminate shadow/duplicate rules and reduce attack surface.

Automation, CI/CD, and Infrastructure as Code

• Develop reusable Terraform modules and Ansible playbooks; enforce code reviews, linting, policy-as-code, and test gates in pipelines.
• Build validation and drift-detection tooling using APIs and scripting (e.g., Python); integrate automated rollbacks and canary changes.
• Champion GitOps practices, configuration data modeling, and inventory source of truth.

Cross-Team Collaboration and Operations Excellence

• Partner with SRE, platform, and security teams on architecture reviews, incident response, post-incident remediation, and capacity planning.
• Lead portions of on-call response and complex change events; coordinate with related teams to minimize risk and downtime.
• Contribute to cross-LOB standards, reference architectures, and service onboarding patterns.

Documentation, Reviews, and Standards

• Produce and maintain high-quality design docs, network diagrams, runbooks, and inventories; ensure traceability to requirements and controls.
• Facilitate and participate in design/change reviews; capture decisions and lessons learned; evolve patterns and modules accordingly.
• Mentor junior engineers via code/document reviews, pairing, and knowledge shares.

Job Qualifications

Network Engineering Expertise & Experience: Core 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.

Cloud 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.

Security and compliance: Zero-trust segmentation, ACLs/policies, IPsec/TLS, DDoS/WAF patterns; familiarity with audit frameworks and evidence practices; change/access control rigor.

Automation 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.

Observability: Designing and operationalizing SNMP/telemetry, NetFlow/IPFIX, flow logs; SLI/SLO definition; capacity modeling and performance tuning.

Operations: Seasoned in incident management, on-call, RCAs, and structured change management; able to lead complex maintenance events.

Collaboration and communication: Clear technical writing, effective reviews, and the ability to influence related teams; comfort presenting trade-offs to stakeholders.

Problem solving and innovation: Uses judgment on multi-variable problems; leads small-scale innovation/improvement initiatives; evaluates alternatives and fallout to ensure safe adoption.
