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.
