About The Position

Designs, implements, and operates resilient L3/L4 network services across data centers and cloud environments, with influence beyond the immediate team. Leads moderately complex projects, scales automation and observability, contributes to standards and architectures, and mentors junior engineers. Works with SRE, platform, and security partners to deliver secure, compliant, highly available network services with measurable team and group impact. The role covers network topology and overlay design, cloud networking implementation and operations, security controls and compliance, infrastructure-as-code and CI/CD automation, monitoring and SLOs, cross-team operations, documentation, reviews, and standards. It also coordinates moderately complex project work, supports organizational collaboration and continuous improvement, and contributes to hiring and team development.

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 designs through lab or sandbox testing, failure modeling, and staged rollouts.
Author design documents and lead reviews with related teams; prepare method-of-procedure, rollback, and verification plans to reduce change risk.
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.
Maintain consistent network policy and connectivity across environments using standard blueprints and golden configurations.
Engineer segmentation, ACLs and policies, encryption, and DDoS/WAF integrations aligned with zero-trust principles.
Embed compliance guardrails, partner with security/GRC on audits, and review rulebases and routing policies to eliminate duplicate or shadow rules and reduce attack surface.
Develop reusable Terraform modules and Ansible playbooks; enforce code reviews, linting, policy-as-code, and pipeline test gates.
Build API- and scripting-based validation and drift-detection tooling; 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 SLIs/SLOs for availability, latency, loss, and jitter; build dashboards, alerts, and runbooks; lead capacity and performance reviews and right-sizing actions.
Correlate telemetry with incidents, lead problem management, and reduce repeat 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; record decisions and lessons learned and evolve patterns and modules accordingly.
Mentor junior engineers through code and document reviews, pairing, and knowledge sharing.
Manage and coordinate moderately complex tasks, monitor timelines and deliverables, and ensure project requirements are met; delegate, prioritize, and provide technical oversight across projects.
Collaborate across the organization, align expectations, and ensure solutions address stakeholder and customer needs while supporting an inclusive environment.
Analyze moderately complex problems using available data, document strategies, and escalate unresolved or critical issues with assessments and potential solutions.
Pursue learning and feedback, stay current with industry trends, and coach junior team members.
Recommend and help implement process improvements, seek feedback on alternative approaches, and evaluate impact on stakeholders.
Participate in candidate interviews, assess candidates, and provide hiring recommendations.
