Job description

About this position

Safety, health and innovation are essential in our rapidly changing world. At TNO, we apply knowledge and technology to develop groundbreaking innovations that contribute to peace, security, vitality and sustainable employability. Together with governments, universities, hospitals and industry partners, we help shape the world of tomorrow. TNO carries out both public tasks and commercial activities, creating a unique and challenging environment with a wide variety of procurement questions. As a Purchasing Support Employee, you will use your up-to-date knowledge and fresh perspective to support the innovative strength of our entire organisation.

What will be your role?

As a Purchasing Support Employee, you will be part of a team of approximately ten colleagues responsible for providing efficient support to TNO’s procurement administration processes. You review purchase requests submitted through our procurement system (Ariba) and help colleagues across the organisation with questions related to the procurement process. In addition, the team is responsible for registering procurement contracts, creating new suppliers in our systems, and supporting the resolution of pricing and quantity discrepancies within the administrative purchasing process.

The Purchasing Support department is evolving from a primarily transaction-focused function into a more advisory role for internal stakeholders. To support this transition, we are continuously improving and optimising our processes, enabling the team to provide greater guidance and support throughout the procurement journey. These changes, which involve updated procedures and, in some cases, new systems, require the Purchasing Support team to play an active role in helping TNO colleagues navigate and adopt new ways of working.

What we expect from you

As part of the Purchasing Support team, you are responsible for the day-to-day processing of procurement requests across the organisation. You review incoming requests and route them to budget holders for approval, ensuring that purchase orders can be issued to suppliers in a timely manner. You support the monitoring of delivery schedules and liaise with suppliers when delays, discrepancies or other issues arise. In addition, you have experience with or an interest in contract administration, including the accurate registration, maintenance and monitoring of contract data.

You are a pragmatic, proactive and confident colleague who enjoys working with both internal stakeholders and suppliers. You gain satisfaction from guiding procurement requests through to a successful outcome and ensuring colleagues receive the support they need. With your customer-focused mindset, flexibility and efficient way of working, you contribute to a smooth and effective procurement process.

You are also able to critically assess your own work and the processes within the team. You share observations and improvement ideas with your colleagues and the Operational Procurement Coordinator, helping to continuously enhance the quality of our services and the efficiency of our procurement processes.

What you bring

• A completed MBO-level qualification in Procurement Management, Business Administration, Business Economics, or a related field.
• Experience with, or an interest in, administrative contract management and contract registration is an advantage.
• Experience with SAP S/4HANA and/or Ariba is an advantage.
• Excellent command of both Dutch and English, at a minimum C1 level, with strong verbal and written communication skills.

What you'll get in return

Challenging and varied work with a real impact. And plenty of opportunities as, at TNO, you are in charge of shaping your career.

We offer a gross monthly salary between € 2,600 and € 3,500 (based on your knowledge and experience), 8% holiday pay, a 13th month bonus of 8.33% and a flex budget (5.58% + € 180). In addition, you will be given every opportunity to develop yourself.

TNO offers optional employee benefits, enabling you to tailor your benefits package to match your personal situation. You may also expect:

• An extremely professional, innovative working environment where colleagues are leading experts in their field.
• The opportunity to attend courses, workshops and conferences, and to receive training and coaching based on your needs.
