About The Position

The Senior Network Engineer is a hybrid engineering and operations leader responsible for designing, implementing, securing, and supporting enterprise network services across on-premises and cloud environments. In addition to core networking expertise, this role is expected to drive automation and leverage AI capabilities to improve operational efficiency, standardization, and scalability—particularly in areas such as Palo Alto firewall configuration management and deployment workflows.

Requirements

7+ years in enterprise network engineering (LAN/WAN/security/cloud)
Strong hands-on experience with Palo Alto firewalls
Strong hands-on experience with Cisco routing (BGP, OSPF, EIGRP)
Strong hands-on experience with Cisco Meraki
Strong hands-on experience with Azure networking
Proven ability to operate in a build + run (50/50) environment
Experience developing or using automation (scripting, APIs, infrastructure-as-code)

Nice To Haves

Experience with Palo Alto automation (Panorama APIs, scripting, orchestration)
Knowledge of automation tools (e.g., Python, Ansible, Terraform)
Familiarity with AI/ML-driven operational tools or observability platforms
Relevant certifications (CCNP, Palo Alto certifications, Azure networking)

Responsibilities

Design, deploy, and manage Palo Alto NGFW infrastructure including policies, NAT, VPN, and segmentation
Manage centralized configuration via Panorama and ensure consistency across environments
Lead firewall optimization, rule lifecycle management, and security posture improvements
Develop and implement automated firewall rule deployment (“push automation”) using APIs, scripting, or orchestration tools
Reduce manual changes by building standardized templates and policy models
Explore and implement AI-assisted workflows to identify redundant or unused rules, recommend rule optimization or cleanup, and detect anomalies or misconfigurations in policy sets
Integrate firewall automation into CI/CD-style pipelines where applicable
Partner with security teams to align automation with governance and audit requirements
Deploy and support Meraki MX/MS/MR infrastructure across distributed environments
Standardize configurations for rapid store/branch rollout
Automate repetitive tasks (config templating, provisioning, monitoring Workflows)
Develop AI monitoring capabilities with the goal of issue identification, notification and remediation within Meraki
Configure and support routing protocols (BGP, OSPF, EIGRP) and enterprise switching
Troubleshoot complex network issues including packet-level analysis
Contribute to resilient network design and failover strategies
Design and manage Azure networking (VNets, subnets, routing, NSGs, connectivity)
Implement hybrid connectivity (ExpressRoute / VPN) between on-prem and cloud
Align network patterns with secure cloud architecture principles
Identify and eliminate repetitive operational tasks through automation
Build reusable automation frameworks across firewall changes (Palo Alto focus), network provisioning and configuration, and monitoring and alerting workflows
Evaluate and introduce AI-assisted tooling to improve troubleshooting accuracy, enhance observability and predictive insights, and support decision-making in network and security operations
Drive adoption of automation across the team (documentation, standards, mentoring)
Act as a technical lead and escalation point across networking and security domains
Mentor engineers on both networking fundamentals and automation practices
Lead cross-functional initiatives (network, cloud, security, operations)
Influence roadmap decisions with focus on scalability, automation, and efficiency
Balance delivery of projects with ownership of operational health
