Duties :

Design and implement network changes across Bay Area sites and global locations (campus, data center, WAN / SD WAN, remote access, cloud interconnects).

Architect and operate AWS networking : multi account VPCs, Transit Gateway, Direct Connect, VPN, endpoints / PrivateLink, Route 53, ALB / NLB, security groups / NACLs, segmentation guardrails.

Build infrastructure as code (Terraform) : reusable modules, CI / CD pipelines, automated pre / post change validation, drift detection.

Lead advanced L2–L7 troubleshooting; drive incidents to resolution and root cause across on prem and AWS.

Apply SRE practices : define SLIs / SLOs / alerts, participate in and lead on call, run incident response and postmortems, maintain runbooks and dashboards.

Partner with Security, SRE / Infra, Workplace, and other IT teams; lead design reviews and cross functional projects.

Document architectures and operational procedures; mentor junior engineers.

Infoblox (DNS / DHCP / IPAM, API automation)

Tooling : Terraform, Git / GitHub, Ansible / Nornir, Python / Go, CloudWatch, Datadog (or similar)

How you'll measure success :

Reliability : higher availability and lower MTTR for campus / core / AWS connectivity via defined SLIs / SLOs.

Safe velocity : automated, tested IaC pipelines; fewer change-related incidents and less toil.

Delivery : on-time multi-site upgrades and AWS networking projects that move team OKRs.

Enablement : durable docs / runbooks and mentorship that uplevel the team.

Requirements :

5+ years designing and operating large scale enterprise networks across hybrid environments (offices, data centers, AWS).

Hands on AWS networking (VPC, TGW, DX, VPN, Route 53, ALB / NLB, endpoints / PrivateLink, Flow Logs) and security guardrails.

Palo Alto Networks firewalls and Panorama : policy design, segmentation, GlobalProtect, threat services.

Juniper campus / data center and Cisco Meraki at scale; strong Cisco Wi Fi design / operations.

IaC and automation : Terraform modules, code reviews, CI / CD; Python or Go; Ansible / Nornir; device / cloud APIs.

Observability and SRE fundamentals : SLIs / SLOs, alerting, incident response / on call, postmortems, runbooks.
