JOB TITLE: OPERATIONAL EXCELLENCE MANAGER SERVICE

LANGUAGES: FRENCH OR DUTCH, ENGLISH

CONTRACT DURATION: 23/11/2026 - 31/12/2027

JOB DESCRIPTION

ROLES AND RESPONSIBILITIES

• Our Grid Development (GD) department sets the standard: its grid studies are a recognized reference, and both Client and society want to leverage this expertise even more. With demand growing fast (more client connection studies, richer development plans, a rapidly electrifying society), it’s time to scale up smartly. That’s where you come in. As Operational Excellence Manager, you will build and lead the GD Center of Excellence and turn our ambition into a structured plan that makes our teams faster, sharper and more satisfied in their work.

What you’ll do:

• Shape the roadmap: partner with the GD Core Team to turn the strategic roadmap into a structural operational excellence plan, and make it happen.
• Steer priorities: drive the quarterly planning and reprioritization cycle and coordinate resource planning across GD teams.
• Make performance visible: define the KPIs, launch a monthly GD dashboard and run the operational dialogue where data turns into actions and decisions.
• Bring structure to key documents: design a document management system for key GD documents, from a System Planning pilot (end 2027) to a GD-wide roll-out, so decisions are traceable and reporting is transparent.
• Unlock efficiency: embed a continuous improvement framework that identifies, evaluates and implements improvements in processes, tools and ways of working, and measures their impact on efficiency and quality.
• Build the Center of Excellence: set up the GD Center of Excellence with shared guidelines, tools and best practices, and align the PMOs within GD to avoid redundancy.
• Deliver: lead specific GD projects from idea to implementation, and make sure the changes stick.

REQUIREMENTS:

• You hold a master’s degree in engineering (civil, commercial, …) or economics, or have equivalent experience;
• You have 4+ years of experience in operational excellence, including defining KPIs, building dashboards (e.g. Power BI), optimizing processes and managing documents;
• You have a basic knowledge of Client and the energy sector;
• You strive for excellence: you spot improvement opportunities and turn them into results, rigorously and on time;
• You are a change maker with a service mindset: you engage stakeholders inside and outside GD and help teams succeed rather than pushing your own agenda;
• You work autonomously and flexibly, set the right priorities, make decisions and communicate clearly with management;
• You are a hands-on doer with a get-things-done attitude: you roll up your sleeves, turn plans into concrete actions and deliver tangible results, even when not everything is perfectly defined;
• You are assertive and an excellent communicator, with a good knowledge of English and fluency in French or Dutch (and at least a good understanding of the other).
