Designs, implements, and operates resilient L3/L4 network services across data centers and cloud environments. Owns well-defined projects end-to-end with autonomy, contributes to standards, and improves reliability through automation and observability. Collaborates primarily within the immediate team and with adjacent SRE, platform, and security teams to achieve team goals with measurable impact on availability, performance, and operational efficiency. Acts as a peer mentor, apply established techniques, and propose cutting-edge improvements that enhance existing systems and processes.
Responsibilities
Key Responsibilities
L3/L4 Network Topologies and Overlays:
• Design IP addressing and routing policies (BGP/OSPF/IS-IS), EVPN/VXLAN fabrics, and SDN overlays across data centers and cloud providers.
• Implement network segmentation, ECMP, high availability, and traffic engineering aligned to SLOs and capacity plans.
• Execute changes via approved change processes; validate via pre/post checks and rollback plans.
Cloud Networking Implementation and Operations:
• Configure and manage VPC/VNet constructs, subnets, routing tables, NAT, private/secure connectivity (TGW/VCN peering, PrivateLink/Service Endpoints), and cross-cloud interconnects.
• Deploy and tune L4/L7 load balancing and service insertion (e.g., proxies, firewalls) to meet performance and resilience goals.
• Ensure consistent policy and connectivity across on-prem and cloud, leveraging standard blueprints.
Network Security Controls and Compliance Guardrails:
• Implement segmentation (VRFs, security zones), ACLs/policies, encryption (IPsec/TLS), and DDoS/WAF integrations following zero-trust principles.
• Apply and maintain compliance controls and evidence (e.g., change records, rule reviews, least-privilege access) in partnership with Security/GRC.
• Continuously review and optimize firewall and routing policies to reduce risk and improve performance.
Automation, CI/CD, and Infrastructure as Code:
