Sales Support Professional Health & Work | Leiden/Hybride - 24u-36u

Do you want to make your mark on the healthcare of tomorrow? As a Sales Support Professional (24–36 hours per week) at TNO Health & Work, you support Business Development by carefully and efficiently organizing the commercial process. With your overview, accuracy, and strong sense of collaboration, you contribute to innovations that truly make a societal impact.

In this role, you ensure accurate system registration, high-quality proposals, and reliable reporting, enabling colleagues to focus on client relationships and creating impactful partnerships. You work closely with colleagues from Market, Finance & Control, Legal, and other internal stakeholders, making an important contribution to a professional and compliant sales process within TNO.

As a Sales Support Officer, you support Business Development by providing structure, clarity, and quality. You work independently, switch easily between tasks, and manage priorities effectively. Together with other Sales Support colleagues, you ensure proper coverage and support for the department.

Additionally, if you wish, there is room to take on other departmental or TNO-wide tasks — ensuring your role remains varied and engaging.

Your responsibilities include, among others:

• Supporting Business Development in the administrative and procedural aspects of the sales process.
• Managing and updating CRM data (leads, opportunities, and client information).

• Performing financial and system-related tasks, such as credit checks, price lists, and purchase orders.
• Liaising with internal stakeholders, such as Research Managers, Finance & Control, Legal, and Product Leads.
• Supporting trade fairs, conferences, and events in collaboration with Marketing & Communications.

You are often one step ahead of your colleagues thanks to your strong planning and prioritization skills. You anticipate what is needed, switch quickly between tasks, and communicate clearly when something is not feasible. With your engaged and positive attitude, colleagues find it easy to approach you.
