Responsibilities

Lead designs for IP addressing, routing policies (BGP/OSPF/IS-IS), EVPN/VXLAN fabrics, and SDN overlays across on-premises and cloud environments.
Define high-availability, ECMP, and traffic-engineering patterns; validate them through lab or sandbox testing, failure modeling, and staged rollouts.
Author design documents and lead reviews with related teams; reduce change risk with method-of-procedure, rollback, and verification plans.
Implement and operate VPC/VNet topologies, subnets, routing tables, NAT, Transit/Hub-and-Spoke connectivity, PrivateLink/service endpoints, and inter-cloud connectivity.
Design and tune L4/L7 load balancing and service insertion, including proxies and firewalls, to meet SLOs and cost targets.
Ensure consistent network policy and connectivity across environments using standard blueprints and golden configurations.
Engineer segmentation, ACLs and policies, encryption, and DDoS/WAF integrations aligned to zero-trust principles.
Embed compliance guardrails, including change control, least-privilege access, and evidence collection, and partner with security/GRC on audits.
Review rulebases and routing policies periodically, removing shadow or duplicate rules and reducing attack surface.
Develop reusable Terraform modules and Ansible playbooks; enforce code reviews, linting, policy-as-code, and pipeline test gates.
Build validation and drift-detection tools using APIs and scripting, integrate automated rollbacks and canary changes, and champion GitOps, configuration data modeling, and a source of truth for inventory.
Implement SNMP/streaming telemetry, NetFlow/IPFIX, and flow logs for health, capacity, and security analytics.
Define availability, latency, loss, and jitter SLIs/SLOs; build dashboards, alerts, and runbooks; lead capacity/performance reviews and right-sizing actions.
Correlate telemetry with incidents, lead problem management, and reduce recurring issues.
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, coordinating with related teams to minimize risk and downtime.
Contribute to cross-LOB standards, reference architectures, and service onboarding patterns.
Produce and maintain design documents, network diagrams, runbooks, and inventories, ensuring traceability to requirements and controls.
Facilitate and participate in design and change reviews; document decisions and lessons learned and evolve patterns and modules.
Mentor junior engineers through code and document reviews, pairing, and knowledge sharing.
Manage and coordinate moderately complex tasks, timelines, deliverables, and work across multiple projects; provide technical oversight and adjust plans as resources or timelines change.
Collaborate across the organization to align expectations and meet stakeholder and customer needs, while seeking and respecting diverse perspectives.
Analyze information to address moderately complex problems, escalate unresolved or critical issues with an assessment and potential solutions, and document problem-solving strategies.
Pursue learning and feedback, keep abreast of industry trends, and coach and mentor junior team members.
Recommend and help implement process improvements, evaluate their impact, and solicit feedback on alternative approaches.
Participate in candidate interviews, assess candidates, and provide hiring recommendations.
