**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.
