Lead Cloud Infrastructure Engineer (Azure+AWS)

Job Summary: We are hiring a Lead Infrastructure & Cloud Engineer with a strong Wintel infrastructure foundation and current, hands-on capability in modern cloud infrastructure across Azure (primary) and AWS. This role exists to close a capability gap: we have deep on-prem expertise, and we need a leader who can define and drive modern cloud standards, guide technical direction, and uplift the team. You’ll operate as a technical lead with an architecture mindset: creating reference designs, setting guardrails, making pragmatic trade-offs (security, resilience, cost), and leading delivery across infrastructure and hybrid cloud. This is not a DevOps role, you will collaborate with DevOps and engineers, but your focus is infrastructure/platform, governance, reliability, and technical leadership. Job Responsibilities: Cloud & Hybrid Architecture (Azure & AWS) • Own the target-state hybrid cloud architecture and roadmap (12–24 months), aligning security, resilience, and cost requirements. • Define reference architectures and standards: landing zones, network patterns, identity patterns, logging/monitoring, backup/DR, and environment separation. • Lead design and implementation of secure cloud networking: VNets/VPCs, routing, VPN, ExpressRoute/Direct Connect, Private Link/Endpoints, load balancers, WAF where needed. • Own cloud governance foundations: subscriptions/accounts, management groups, RBAC, naming/tagging, logging, budgets and policy guardrails. Modern Cloud Operations (Hands-on Leadership) • Ensure cloud platforms, services, and workloads remain on supported, secure versions; implement drift detection and lifecycle management. • Establish platform observability: Azure Monitor/Log Analytics/App Insights, CloudWatch, OpenTelemetry where used; improve alert quality and operational readiness. • Build and maintain backup/DR posture with tested RTO/RPO, runbooks, and regular restore/DR exercises. • Drive FinOps discipline: cost allocation, tagging compliance, rightsizing, reservations/savings plans, and cost anomaly detection. Security, Governance & Incident Readiness • Ensure security controls are in place and effective (least privilege, secure baselines, encryption, key management, vulnerability/patch posture). • Log & telemetry onboarding: own onboarding of data/log sources and integration with the SIEM (e.g., Microsoft Sentinel/Splunk) in partnership with Security. • Lead incident response for infrastructure/cloud events: triage, investigation, reporting, RCA, and implementation of preventative controls and guardrails. • Manage, document, and audit configuration changes; champion “repeatable by design” changes and reduce configuration drift. Wintel & Core Infrastructure Leadership • Provide technical leadership across core infrastructure services: Windows Server, AD DS, DNS/DHCP, certificates/PKI, and integration with Entra ID. • Guide virtualisation/storage teams (VMware/Hyper-V, SAN/storage) towards cloud-aligned standards for resilience, security, and lifecycle. Leadership and Uplift • Act as the technical authority for infrastructure and hybrid cloud lead technical decisions and drive outcomes. • Mentor and upskill engineers on modern cloud infrastructure practices; run knowledge sessions and codify standards into reusable patterns. • Provide input during design and architectural discussions with DevOps and software teams; unblock delivery with clear, pragmatic guidance. Requirements Must-Have Skills & Experience • Strong enterprise infrastructure background with a Wintel core (Windows Server, AD, DNS/DHCP, certificates) and operational discipline. • Demonstrable, hands-on Azure production experience including: • Identity/RBAC/Entra integration • VNets, VPN/ExpressRoute, Private Link/Endpoints • Azure Monitor/Log Analytics, backup/DR patterns, policy/guardrails • Working knowledge of AWS production environments (accounts/VPC, security groups, IAM basics, CloudWatch). • Strong troubleshooting and incident leadership across OS/network layers; confident with vendors/escalations. • Scripting/automation mindset (strong PowerShell; Bash/Python beneficial). • Ability to create architecture artefacts: reference designs, diagrams, standards, and decision records (ADRs). Preferred Certifications AZ-104 , AZ-305 or AZ-500 Desirable • Conditional Access and privileged access controls (PIM), break-glass patterns, Zero Trust principles. • Azure Policy/AWS Config, Defender for Cloud/Security Hub, GuardDuty; landing zone governance tooling. • AWS Control Tower, IAM Identity Center, CloudFormation (read/maintain). • Infrastructure-as-Code familiarity (Terraform/Bicep) preferred, but not essential. • Exposure to containers/AKS/EKS and CI/CD concepts (as an enabling partner). • Experience supporting web hosting environments (CDN/WAF, TLS/PKI, caching/performance).
