Infor is looking for a Senior Network Administrator with deep expertise in cloud networking, AWS cloud infrastructure, and VPN technologies. This role sits at the intersection of networking and cloud engineering, with a primary focus on designing, implementing, and maintaining secure, high-performance network architectures across hybrid and cloud-native environments. Success in this role requires strong ownership, problem-solving ability, and a commitment to automation, reliability, and security best practices.

You will work heavily with the network layer of enterprise customer environments — from VPN tunnels and transit gateways to DNS, firewall policies, and traffic routing — while applying Dev Ops principles of automation, observability, and infrastructure as code throughout.

• Support customers across the U.S. by maintaining reliable network environments and participating in an on-call rotation to ensure rapid response and system uptime
• Partner directly with customers and their network teams to troubleshoot issues, resolve escalations, and optimize performance
• Design, deploy, and maintain enterprise network architectures across AWS and hybrid environments, including routing, firewalls, VPNs, and segmentation
• Monitor network performance (latency, throughput, packet loss), lead incident response, and perform root cause analysis to prevent future issues
• Architect and manage AWS networking services (VPC, Transit Gateway, load balancers, DNS), ensuring security, scalability, and compliance
• Drive automation and efficiency through infrastructure as code, CI/CD pipelines, and scripting, while contributing to observability and monitoring improvements

• Experience in network engineering, cloud infrastructure, or Dev Ops roles within enterprise environments
• Experience engaging directly with customers to gather requirements, lead technical discussions, and design network solutions, including whiteboarding and collaborating on architecture decisions
• Hands‑on expertise with AWS networking, including VPC, Transit Gateway, Direct Connect, VPC Endpoints, and hybrid architectures
• Experience with advanced networking protocols and concepts, including TCP/IP, DNS, BGP, IPsec, TLS, routing, segmentation, and firewall design
• Experience designing and managing VPN solutions at scale (site-to-site and client VPN), including troubleshooting complex connectivity issues
• Proficiency with infrastructure as code and automation, using tools such as Terraform, Cloud Formation, and CI/CD platforms (Git Hub Actions, Git Lab CI, Jenkins)
• Experience across Linux and Windows networking environments, using tools such as tcpdump, trace route, mtr, and Wireshark, along with exposure to enterprise network hardware (Cisco, Fortinet, Palo Alto, etc.)
• Must be willing to work 3 days per week in the office
• Legal authorization to work permanently in the United States for any employer without requiring a visa transfer or sponsorship now or in the future

• AWS Networking and/or Solutions Architect certification
• Familiarity with zero‑trust network architectures and SASE frameworks
• Experience with multi‑region or global network architectures
• Familiarity with compliance frameworks (SOC 2, HIPAA, PCI‑DSS) as they relate to network controls
