LocationDublin (Hybrid) - flexibility for occasional travel project sites.

Summary / Role Overview

We are seeking a Technology Project Manager to lead complex, large-scale migration programs spanning application portfolios, infrastructure platforms, and associated services (e.g., data, identity, networking, and security). The ideal candidate has a proven track record delivering end‑to‑end migrations-such as on‑prem to cloud/Hybrid, data center migrations, app replatforming, and identity/network transitions-while balancing delivery speed, risk, and quality.
You will orchestrate cross‑functional teams (business, technology, security, operations, vendors), build and manage detailed plans, control scope and budget, and proactively remove blockers to ensure business continuity and compliant outcomes.

Key Responsibilities

Program / Project Delivery

• Own end‑to‑end planning and execution of migration projects (discovery, assessment, design, build, cutover, hypercare).

• Develop integrated project plans, detailed migration wave plans, dependency maps, and critical path tracking.

• Drive effective governance: status reporting, RAID (Risks, Assumptions, Issues, Dependencies), steering committee updates, and change control.

Technical Orchestration

Continuous Improvement

• Capture and apply lessons learned across waves; refine frameworks, playbooks, and templates.

Core Competencies

• Delivery Excellence: Mastery of project planning, RAID management, status reporting, and change control in multi‑workstream programs.

• Technical Acumen: Strong understanding of application architectures, infrastructure (compute, storage, network), cloud platforms (Azure/AWS/GCP), identity (AD/Azure AD/Entra), and security controls.
