• Design and deploy campus and access-layer switching infrastructure (Meraki MS, Aruba CX) including VLAN design, spanning tree, and port security
• Deploy and optimize enterprise wireless environments using Cisco Meraki and/or Aruba platforms
• Troubleshoot and tune RF performance, SSID design, and wireless client connectivity issues
• Security & VPN
• Configure and manage next-generation firewalls (Palo Alto Networks) including policy, NAT, and threat prevention
• Implement and support Prisma Access for SASE/remote access use cases
• Configure and manage network access control (NAC) solutions including Aruba ClearPass and Cisco ISE for 802.1X, device profiling, and policy enforcement
• Deploy and maintain VPN connectivity including GlobalProtect remote access and site-to-site IPsec tunnels using Velocloud Gateways
• Technical Project Ownership
• Drive concurrent network projects end-to-end, serving as the technical owner for each engagement
• Collaborate with project managers, field services, server, network operations, clinical applications, and other Ethos teams
• Provide accurate, meaningful status updates on project milestones, change control requests, and operational issues
• Documentation & Standards
• Create and maintain technical documentation including network design diagrams, operational procedures, and standards documentation
• Support implementations tied to clinical and operational systems such as VoIP, clinical applications (ezyVet), and biomedical devices (DICOM protocol)
• Clearly explain design decisions (e.g., switch stacking, redundancy, scalability) to audiences of varying technical depth

Education, License and Job Requirements:

• Technical Skills
• SD-WAN: Deployment, migration, and troubleshooting - Arista SD-WAN (VeloCloud) preferred
• Switching and Wireless: Cisco Meraki and Aruba (AOS / CX) design, deployment, and RF optimization

• VPN: GlobalProtect remote access and site-to-site IPsec VPN configuration and troubleshooting
• Routing and Switching: Strong foundation in BGP, redistribution, VLAN design, spanning tree, LACP
• NAC: Aruba ClearPass and Cisco ISE, 802.1X, device profiling, and posture assessment
• Troubleshooting: Deep understanding of OSI model layers, packet capture analysis, bandwidth utilization, and application-layer debugging

Certifications Required:

• CCNP (Enterprise, Security, or equivalent) or higher
• Preferred: PCNSA/E (Palo Alto), ACSP/ACMP (Aruba), VeloCloud certifications

Skills and Experience:

• Experience 5+ years of progressive network engineering experience with hands-on implementation background
• Minimum 3 years in a senior or lead network engineering role with demonstrated ownership of complex, multi-site WAN/LAN design and deployment
• Experience designing networks for healthcare, hospitality, or similarly complex distributed environments
• Proven ability to manage technical workstreams across multiple concurrent projects

Professional Competencies

• Ability to clearly articulate design rationale and trade-offs to technical and non-technical stakeholders
• Strong documentation, organizational, and technical coordination skills
• Self-directed with the ability to work independently across remote and on-site environments
• Collaborative mindset with experience working across IT disciplines (server, security, clinical apps, field services)

Preferred Qualifications
