Job Description

Role Overview

We are seeking an experienced Technical Delivery Manager to lead the technical delivery, operations, maintenance, enhancement, and lifecycle management of enterprise IT systems.

The role requires a strong combination of technical infrastructure knowledge, project and service delivery management, stakeholder management, and hands-on experience in Linux and/or Windows Server administration.

The Technical Delivery Manager will act as the key technical coordination point between application teams, infrastructure and cloud engineers, cybersecurity teams, business users, vendors, and management. The successful candidate should be capable of understanding complex application and infrastructure issues, challenging technical proposals, coordinating troubleshooting activities, managing incidents and changes, and ensuring solutions are delivered securely and reliably.

This is not purely a project management role. The candidate is expected to possess sufficient technical depth to understand server, operating system, middleware, database, network, cloud, security, and application dependencies and to actively participate in technical discussions and troubleshooting.

Key Responsibilities

Technical Delivery & Operations Management

Lead the end-to-end technical delivery of IT infrastructure, application platforms, system enhancements, migrations, upgrades, and technology refresh initiatives.
Manage day-to-day system operations and ensure availability, performance, security, and reliability of supported environments.
Coordinate activities across application, Linux/Windows, database, middleware, network, cloud, security, and vendor teams.
Review technical designs, implementation plans, migration plans, change requests, rollback plans, test plans, and operational readiness before implementation.
Ensure appropriate technical validation is performed before solutions and changes are presented for management or stakeholder approval.
Track technical dependencies, risks, issues, milestones, and deliverables and drive them through to closure.
Ensure proper transition of newly implemented systems and enhancements into BAU operations.

Linux / Windows Server Administration

The candidate should have strong technical experience in Linux and/or Windows Server administration, with the ability to understand and troubleshoot infrastructure-level issues.

Key competencies should include:

Administration and troubleshooting of Red Hat Enterprise Linux (RHEL) and/or Microsoft Windows Server environments.
OS installation, configuration, hardening, patching, upgrading, and lifecycle management.
Server performance troubleshooting covering CPU, memory, disk, filesystem, I/O, processes, and services.
Linux package and repository management using RPM/YUM/DNF or equivalent technologies.
Windows Server administration including services, Event Viewer, PowerShell, Windows Update/WSUS, scheduled tasks, and system configuration.
User, group, privilege, service account, and access management.
Filesystem, storage, volume, mount point, disk capacity, and log management.
Understanding of server security hardening, vulnerability remediation, endpoint protection, and security controls.
Ability to analyse system and application logs during incident investigation.
Working knowledge of backup, restoration, snapshots, recovery, and disaster recovery procedures.
Understanding of DNS, TCP/IP, firewall rules, ports, certificates, load balancers, and network connectivity required for server/application troubleshooting.
Ability to work with infrastructure engineers to perform root cause analysis and technical problem resolution.
Hands-on administration experience is strongly preferred, as the Technical Delivery Manager is expected to independently understand technical issues and effectively challenge or validate recommendations from engineering teams and vendors.

Incident, Problem & Change Management

Lead and coordinate investigation of major or complex technical incidents across application and infrastructure teams.
Drive restoration of services within agreed operational and SLA requirements.
Coordinate technical troubleshooting and escalation across internal teams, vendors, cloud providers, and other stakeholders.
Review and prepare incident reports, Root Cause Analysis (RCA), corrective actions, and preventive actions.
Ensure root causes are supported by appropriate technical evidence rather than assumptions.
Track preventive and corrective actions through to closure.
Review Change Requests (CR), Emergency Change Requests (ECR), implementation procedures, validation plans, and backout procedures.
Ensure technical risks, dependencies, service impacts, downtime requirements, and rollback strategies are properly assessed before implementation.
Participate in post-implementation reviews for significant changes and incidents.

Vulnerability, Security & Compliance Management

Review infrastructure and application security vulnerability reports and coordinate remediation with the relevant technical teams.
Assess vulnerabilities together with engineers and application owners to determine affected systems, available patches, dependencies, remediation requirements, and implementation risks.
Track vulnerability remediation against applicable SLA requirements.
Coordinate patching and security remediation across development, UAT, and production environments.
Review technical security controls and ensure solutions comply with applicable organisational and government security requirements.
Support IT security assessments, penetration testing findings, vulnerability assessments, and remediation activities.
Ensure technical changes and operational activities comply with applicable IM8 requirements, cybersecurity policies, and IT governance standards.

Audit & Governance

Support and coordinate internal and external IT audits.
Review audit findings and work with technical teams to establish remediation and preventive actions.
Draft and review responses to IT audit observations.
Maintain appropriate technical and operational evidence to support audit requirements.
Ensure operational procedures, system documentation, technical records, and control evidence are maintained and kept current.
Prepare and present monthly operational, security, incident, vulnerability, capacity, and service management reports.

Project & Vendor Management

Manage technical projects covering infrastructure upgrades, application enhancements, migrations, cloud adoption, security improvements, and technology refresh activities.
Develop project plans, implementation schedules, resource requirements, dependencies, risk registers, and delivery milestones.
Manage vendors and service providers and ensure deliverables meet contractual, technical, security, quality, and timeline requirements.
Review vendor technical proposals, solution designs, implementation approaches, effort estimates, and costing.
Evaluate application development and infrastructure implementation costs and challenge estimates where appropriate.
Conduct regular technical and project governance meetings and track actions to closure.
Escalate delivery, operational, security, and resource risks where necessary.

Stakeholder & Business Management

Act as the primary technical interface between business users, application teams, infrastructure teams, cybersecurity teams, vendors, and management.
Understand business and operational requirements and translate them into appropriate technical requirements and delivery plans.
Explain complex technical issues, risks, and proposed solutions clearly to both technical and non-technical stakeholders.
Prepare technical recommendations, management papers, presentations, incident summaries, and decision papers.
Balance technical, operational, security, cost, and business considerations when evaluating proposed solutions.

Technical Environment

Candidates may be required to support environments involving technologies such as:

Operating Systems: Red Hat Enterprise Linux (RHEL), Microsoft Windows Server
Cloud: Microsoft Azure
Application: Java, Spring Boot, Spring Core, Hibernate, React, Bootstrap, jQuery, Pro.C
