Management Assistant in Arnhem

Keeping the Netherlands running, that is our mission.

At TenneT, we are working on an energy system that will continue to provide the Netherlands with reliable, affordable, and sustainable energy in the future. Within the Design division, the Finance & Performance (F&P) and System Integrity (SI) departments play an important role in realizing a future-proof energy system. To optimally support these teams and the Design division, we are looking for a proactive and organizationally strong Management Assistant.

How do you keep the Netherlands powered?

As a Management Assistant, you will support the managers of Finance & Performance and System Integrity and ensure that the daily operations of both departments run smoothly. Additionally, you will play an important role in division-wide support for Design.

You are an organizational talent who switches easily between different tasks, stakeholders, and priorities. Thanks to your commitment, processes run efficiently, meetings are professionally organized, and managers and teams can focus on their substantive contribution to the energy transition.

• Support of Finance & Performance and System Integrity:
• You manage the calendars of the managers of Finance & Performance and System Integrity and ensure efficient planning of appointments and meetings.
• You support team members in organizing and facilitating larger meetings, workshops, knowledge sessions, and gatherings.
• You coordinate with internal and external stakeholders regarding appointments, reservations, and schedules.
• Division-wide support Design:
• You replace fellow Management Assistants within the Design Division during holidays and other absences.
• You manage and maintain the Design SharePoint environment, ensuring that information remains accessible, up-to-date, and well-structured.
• You register and process purchase orders and support administrative procurement processes.
• You coordinate the onboarding of new employees and ensure they quickly find their way within the organization.
• You organize division-wide events and meetings for Design, including arranging locations, catering, invitations, participant registration, and logistical support. You are responsible for the organization and execution, not for the substantive content of the events.

At TenneT, we look for professionals who contribute to an effective and future-proof project organization. We expect you to have the right experience and skills to make a valuable contribution to our team and our mission.

Therefore, we ask of you:

• A completed education at mbo+ or hbo level.
• Experience in a supporting, administrative, or coordinating role within a dynamic environment.
• Experience with Microsoft Office, Outlook, Teams, and SharePoint.
• Experience with administrative processes and processing procurement requests is a plus.
• Experience with organizing meetings and events is a plus.
• Excellent command of the Dutch language and a good command of English, both spoken and written.
• The ability to work independently while simultaneously collaborating effectively with diverse stakeholders.

To truly make a difference in this role, you recognize yourself in the following competencies;

• Action-oriented: you actively take on tasks, take responsibility for your results, and ensure that agreements are met.
• Optimizing work processes: you work in a structured manner, have an eye for quality, and think along about improvements that make processes more efficient and effective.
• Organizational sensitivity: you build relationships easily, work pleasantly with colleagues and stakeholders, and navigate effectively within the organization.
• Adaptability: you switch smoothly between tasks and easily adapt to changing circumstances and priorities.
• Effective communication: you know how to convey information clearly and purposefully and tailor your communication to your interlocutor.
• Result-oriented: you maintain focus on agreed goals, work accurately, and ensure that tasks are completed on time and with the correct quality.
