Group Senior Infrastructure Engineer

JOB PURPOSE
The Group Senior Infrastructure Engineer is a senior technical lead who owns the design, automation, security, and operational health of infrastructure across Ports and Terminals products hosted on Microsoft Azure, on-premises, and hybrid environments. Working in a hybrid Engineering and Operations model, the engineer builds platforms and remains accountable for their availability and continuous improvement in production. They partner with Solutions Architect, Development, Database, Security, and DevOps teams to keep platforms scalable, resilient, secure, cost-efficient, and aligned with enterprise architecture. The engineer drives automation and standardization across the estate using tools such as Terraform, Ansible, PowerShell, and Python, establishes golden images and reference architectures, and systematically reduces manual work. They are responsible for security baselines, patching and vulnerability remediation, least-privilege access, and audit readiness, working closely with the Security team. The engineer owns the lifecycle of compute, storage, networking, virtualization, containers, identity, monitoring, backup, and disaster recovery across a multi-site terminal estate. They translate business continuity needs into RTO and RPO targets, design failover strategies, lead DR testing, and document architectural trade-offs with the stakeholders who depend on them.
The role will strategically carry significant operational leadership. The engineer leads major incident response and complex troubleshooting across SLA-tiered priorities and drives root-cause analysis to permanent fixes. They put proactive monitoring and capacity planning in place.

Automation and Operational Excellence

-  Automate infrastructure provisioning, configuration, compliance, and operational activities using Infrastructure as Code, Azure CLI, PowerShell, Bash, Python, and approved CI/CD tooling.

-  Drive standardization, reusable templates, self-service capabilities, configuration consistency, and reduction of manual operational effort.

-  Implement effective monitoring, alerting, logging, capacity management, performance optimization, asset management, and service-health reporting.

Reliability, Incident Management, and Recovery

-  Provide senior technical leadership during critical incidents, coordinate cross-functional troubleshooting, restore services within agreed priorities, and communicate clear technical status and risk.

-  Lead root-cause analysis and post-incident reviews, identify corrective and preventive actions, and ensure actions are tracked through closure.

-  Design, maintain, and test backup, restore, high-availability, disaster recovery, and business-continuity capabilities against approved service requirements.
JOB CONTEXT
This role operates across cloud and on-premises infrastructure in a hybrid environment, sitting at the intersection of cloud platforms, infrastructure operations, information security, applications, and databases. It balances day-to-day service reliability and incident resolution with longer-term work on automation, standardization, security hardening, capacity, resilience, and cloud modernization.
Success contributes to stable infrastructure services, lower operational and security risk, improved efficiency, and dependable recovery capabilities. The role supports cross-functional teams running complex, distributed systems for diverse customers with varying technical needs and service level expectations, and requires moving between urgent operational demands, such as incident response and customer escalations, and strategic initiatives that improve how the estate is automated, standardized, and optimized.
