Description

Sibelga's Technology Center is continuing a transformation focused on stronger operational efficiency, cross-functional collaboration and execution capabilities. The Senior PMO & Performance Officer will design, implement and continuously develop a structured management and steering framework. The framework must provide clear visibility on priorities, performance, capacity and transformation initiatives. The consultant will work closely with the Head of Projects & Transformation.

The assignment combines enterprise PMO, portfolio management, performance reporting and governance. The consultant will consolidate project and initiative portfolios, structure prioritization and arbitration, contribute to capacity planning, and establish KPI and reporting frameworks. Management dashboards, portfolio reviews, executive summaries and decision-support analyses are central deliverables. The role also requires follow-up of decisions and strategic initiatives.

The consultant will help structure the Technology Center's operating model, governance and organization. This includes clarifying roles and responsibilities, mapping interfaces, identifying organizational gaps and friction points, and strengthening cross-functional collaboration. The role also develops common project-management methods, templates, frameworks and standards and supports their adoption. Continuous improvement and the further maturity of the Technology Center's PMO model are important parts of the mission.
