Key Responsibilities
- Mainframe modernization enablement
- Partner with application and platform teams to migrate and modernize mainframe-adjacent workloads (e.g., rehost/refactor components, distributed integrations, data movement patterns).
- Design target-state infrastructure and transition architectures for Azure, including landing zones and platform services alignment.
- Azure infrastructure engineering
- Build and operate Azure core services: VNETs/subnets, routing, NSGs, Azure Firewall, Private Link, DNS, identity integrations, and resource organization (subscriptions, management groups, tagging).
- Implement Infrastructure as Code (IaC) using Terraform/Bicep and integrate with CI/CD pipelines.
- Hybrid connectivity & network performance
- Design, implement, and troubleshoot on-prem ↔ Azure connectivity using ExpressRoute, VPN, Virtual WAN, and hub/spoke (or vWAN) architectures.
- Configure and validate routing (BGP), MTU/MSS settings, latency/throughput baselines, and failover behavior.
- Tune connectivity performance for critical flows (batch, file transfer, API, messaging, data replication), including bandwidth planning and QoS considerations where applicable.
- Performance tuning & reliability
- Identify and remediate bottlenecks across network, compute, storage, and platform services (e.g., VM sizing, disk throughput/IOPS, load balancing behavior, TCP tuning, connection pooling implications).
- Establish monitoring/observability (Azure Monitor, Log Analytics, Network Watcher, Application Insights where relevant), SLOs, alerting, and runbooks.
- Lead root cause analysis for performance incidents and drive preventative improvements.
- Security, governance, and operational excellence
- Apply cloud security best practices (least privilege, segmentation, private endpoints, key management) and ensure alignment with governance controls.
- Produce clear design documentation, operational procedures, and knowledge transfer.
Required Qualifications
- 10+ years in infrastructure engineering (cloud and/or datacenter), with direct experience supporting modernization or migration from mainframe environments to distributed/cloud platforms.
- Strong, practical experience with Microsoft Azure, especially:
- Networking (VNET, routing, NSG, Azure Firewall, Private Link, DNS)
- Connectivity (ExpressRoute, VPN, vWAN, hub/spoke)
- Compute/storage fundamentals (VMs, disk performance, availability patterns)
- Demonstrated ability to set up, troubleshoot, and performance-tune hybrid connectivity (latency, throughput, packet loss, MTU/MSS, routing, failover).
- Infrastructure as Code experience (Terraform and/or Bicep/ARM) and Git-based workflows.
- Strong troubleshooting skills and ability to work across teams (network, security, app, data).
Preferred / Nice to Have
- Experience with modernization patterns: rehost, replatform, refactor; familiarity with integration with mainframe systems (e.g., batch scheduling, file transfer, messaging, data replication).
- Azure Landing Zone / CAF experience, policy/guardrails, and enterprise subscription design.
- Experience with performance tools and methods (load testing coordination, network path analysis, packet capture interpretation, baseline/SLO definition).
- Containers (AKS), API management, and/or messaging services (Service Bus, Event Hubs) exposure.
