Senior Network Cloud Engineer

As a Senior Network Cloud Engineer, you’ll play a critical role in shaping and supporting Epsilon’s global network infrastructure by designing, implementing, and solving complex network solutions across multiple datacenters and cloud environments. You’ll be part of a passionate team of network professionals, using your deep expertise in routing, switching, load balancing, and network security to implement scalable, automated solutions that meet demanding 24x7x365 operational requirements. Your work will directly influence the performance and reliability of our internal and edge Internet/peering infrastructure, and you’ll collaborate closely with vendors and internal partners to ensure procedures and standards are upheld. If youre a meticulous engineer eager to grow and make a significant impact in a dynamic, service-based enterprise environment, we’d love to connect with you. What You’ll Achieve • Lead the design, implementation, and optimization of network services, tools, and infrastructure across on-premises, hybrid, and multi-cloud environments. • Engineer scalable, automated cloud networking solutions using AWS VPCs, Transit Gateways, Direct Connect, PrivateLink, Route53 Resolver, GCP VPCs, Cloud Interconnect, Cloud DNS, and Azure VNets, ExpressRoute, and Private DNS, ensuring secure and resilient connectivity. • Build and maintain infrastructure as code using Terraform, Ansible, CloudFormation, and Deployment Manager, ensuring configuration consistency, policy enforcement, and preventing drift. • Develop and run Cloud DevOps and CI/CD pipelines for network provisioning, configuration management, and observability. • Automate provisioning, configuration, and monitoring tasks using Python, Go, Bash, and PowerShell, integrating with AWS Lambda, GCP Cloud Functions, and Azure Functions. • Collaborate with SRE, cloud security, and platform teams to ensure alignment with zero trust, compliance frameworks, and cloud-native security controls. • Solve sophisticated hybrid networking issues across LAN, WAN, cloud interconnects, Internet, and routing protocols (BGP, OSPF, EVPN, VXLAN). • Implement cloud load balancers, CDN integrations, DNS failover, and traffic steering policies for high availability and global resiliency. • Evaluate and deploy next-gen technologies, including service mesh, cloud-managed firewalls, cloud-native monitoring, and observability platforms. • Drive adoption of guidelines for cost optimization, tagging strategies, and governance across multi-cloud infrastructure. • Continuously evaluate current systems, pinpoint opportunities for improvement, and put in place effective solutions for automation. • Standardize documentation, runbooks, and design patterns for network and cloud operations. Who You Are • What you’ll bring with you: o 10+ years of experience supporting high-performance production environments. o 3–5 years of hands-on cloud networking experience across AWS, GCP, and Azure. o Demonstrable experience designing and operating secure hybrid multi-cloud networks, including site-to-site VPNs, ExpressRoute, Direct Connect, Cloud Interconnect, and Transit Gateway topologies. o Strong programming and automation skills in Python, with experience in network automation frameworks and cloud SDKs/APIs (boto3, gcloud, azure-cli). o Deep expertise with infrastructure as code and DevOps tooling (Terraform, Ansible, GitHub Actions, Jenkins, GitLab CI/CD, ArgoCD). o Advanced knowledge of networking protocols and technologies including Ethernet (10/40/100/400Gbps), OSPF, BGP, EVPN/VXLAN, IPSec, DHCP, DNS, SNMP, LACP, IPv6, and TCP. o Hands-on experience with enterprise networking platforms such as Cisco Catalyst and Nexus, Dell Force10, Arista, F5 Big-IP, and Palo Alto firewalls. o Expertise in cloud-native firewalls and security groups, Web Application Firewalls (AWS WAF, Azure WAF, GCP Cloud Armor), and DNSSEC/DoH. o Proficiency with cloud-native monitoring and observability tools (CloudWatch, Cloud Logging, Azure Monitor, Prometheus, Grafana, Datadog). o Experience developing cloud networking infrastructure including DNS, CDNs, load balancers, VPCs, subnets, NAT gateways, peering, and service mesh. o Solid understanding of security frameworks and regulations (e.g., ISO 27001, NIST, PCI DSS, CIS Benchmarks). o Demonstrable capability for leading incident response, RCA, and performance tuning across distributed systems. o Familiarity with FinOps practices for cloud cost optimization and forecasting. o Good communication and documentation skills to collaborate across technical and business teams. o Cloud certifications (AWS Solutions Architect/Advanced Networking, GCP Professional Cloud Network Engineer, Azure Network Engineer Associate), along with Cisco/Palo Alto certifications. o Participate in after-hours on-call rotation as needed. • Why you might stand out from other talent: o Hands-on experience building multi-region and multi-cloud network architectures with automated failover. o Demonstrated leadership in driving automation adoption across traditional and cloud networking environments. o Experience with service provider-scale environments or global SaaS organizations. o Demonstrable ability to integrate network operations with DevSecOps pipelines and GitOps workflows. o Led innovative projects to boost operational efficiency through self-service platforms, automation, and AIOps/ML-powered insights. o Demonstrated knowledge of modern technologies, including AI/ML for predictive monitoring, intent-based networking, and cloud-native security analytics
