• Acting as a trusted commercial partner by challenging requirements, defining scopes and guiding stakeholders through supplier selection, negotiation, award and implementation;
• Building effective supplier relationships and commercially following up projects, contracts and performance, including scope, planning, deliverables, budgets, changes, claims and underperformance;
• Managing commercial, contractual, operational and supplier risks, with clear mitigation measures, performance reviews and corrective actions;
• Ensuring accurate contract implementation and follow-up in ERP, contract management and reporting tools;
• Improving transparency and efficiency through data, reporting, standardisation and practical automation solutions;
• Leading cross-functional collaboration and decision-making to achieve the best balance of service, quality, risk, delivery and cost.

Requirements:

Candidates must meet the following requirements:

• Master’s degree and relevant experience in procurement, commercial or contract management, preferably involving outsourced, consultancy, engineering or other project-based services;
• Experience with public procurement, outsourced studies, project management or supplier performance management is an asset;
• Very good command of Dutch or French, preferably Dutch, with a professional understanding of the other language and a professional level of English;
• Ability to manage multiple projects, contracts, suppliers, risks and deadlines while maintaining a clear overview;
• Strong analytical, commercial and negotiation skills, with the ability to turn complex information into practical recommendations and decisions;
• Credible and empathetic relationship builder who communicates clearly and assertively across technical, project and business teams;
• Autonomous problem solver who takes ownership, leads complex files and collaborates effectively;
• Interest in continuous improvement, reporting and practical automation using Excel or comparable low-code tools; programming experience is not required.

Additional information:

• Full-time mission starting in November 2026 and running until the end of 2027, with a strong possibility of extension;
• Based at Elia’s Monnoyer office in Brussels/Schaerbeek, with occasional meetings at other Elia sites and 2–3 home-working days per week.
• Meeting and desk activities will be split between the two Elia Group locations in Brussels, and occasionally the 50Hertz Netzquartier in Berlin (2 days working at the office per week on average).
• In case of travels to Germany, Elia will cover all costs.
