About this position

Working at TNO means contributing to research and innovative solutions that truly matter — from the energy transition and the application of secure AI in healthcare to the future of digital identity and national security.

As a Network Engineer, your challenge is to manage complex network environments that enable more than 4,500 TNO employees across 20 locations in the Netherlands to carry out their daily work and research activities. You have a strong eye for detail and security, and you are comfortable coordinating operational activities and changes.

What will be your role?

As a Network Engineer, you are responsible for ensuring the availability and continuity of the network infrastructure. Your responsibilities include:

Ensuring optimal network performance and system security.
Performing performance measurements and trend analyses, and implementing system improvements where necessary.
Managing and administering infrastructure changes.
Advising on the urgency, impact, and prioritization of proposed changes.
Keeping up to date with the latest technologies and industry trends.
Developing ideas to further enhance the quality and service level of the department.
Maintaining operational relationships with software and hardware vendors.

Because TNO conducts a significant amount of technological research for Defence, the secure availability of our networks is of critical importance — both for TNO and for society as a whole. #

The Team
As a Network Engineer, you will be part of the Infrastructure team. This team is responsible for the data centers, storage environments, networks, Linux and Windows servers, and the core client infrastructure. The team is also responsible for IaaS and PaaS cloud services and their integration with on-premises environments.

The team primarily operates from the Den Haag Nieuw Babylon office, with secondary activities across locations in the central and southern regions of the Netherlands. Hybrid working is standard practice.

What we expect from you

To be successful in this role, you recognize yourself in the following profile:

Bachelor’s degree level of working and thinking (HBO level or equivalent).
Preferably proven experience as a LAN/WAN Network Engineer in a relevant environment.
Demonstrable experience with Cisco, Palo Alto, F5, and Infoblox technologies.
Ability to optimize and automate management and operational tasks.
Flexible, customer-focused, and service-oriented mindset.
Strong analytical and problem-solving skills.
Good command of both Dutch and English.
Possession of a valid Category B driving license.

What you'll get in return

Challenging and varied work with meaningful impact — combined with excellent opportunities for personal and professional growth. At TNO, you largely shape your own career path. In addition to a gross monthly salary (full-time, 40 hours) between €3,450 and €5,250, depending on your knowledge and experience, you will receive a 13th month payment (8.33%) and a flexbudget (5.58% + €180). Including these additional benefits, your total monthly compensation can amount to approximately €4,000 to €6,000 gross per month. And of course you will receive 8% holiday allowance.

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.
33 days annual leave plus a flexible holiday that can be used on a cultural, religious, or otherwise important day of your choosing (on a full-time basis).
An employer working towards a respectful, inclusive, and equitable work environment where every employee can flourish, with various initiatives such as Jong TNO, numerous expertise based guilds, Rainbow Community and Round Tables on diverse inclusion topics.
We offer a comprehensive and flexible mobility plan that also includes full compensation for public transportation for commuting and business travel.
Great social events with your team and other TNO colleagues. That’s how you will get to know a lot of people really quickly.
Flexible working hours, the possibility to work parttime (32 or 36 hours) and the possibility of working from home.

Read more about tailoring your benefits package.

TNO as an employer

Our people are at the heart of TNO. Their curiosity, expertise and entrepreneurial mindset make it possible to deliver high-impact research and innovations that contribute to society’s sustainable wellbeing and prosperity. That is why we invest in an inspiring and inclusive working environment where colleagues can excel, have autonomy and continue to grow.

Your talent and ambition have every opportunity to flourish at TNO. You work with experts (both within and beyond TNO), have access to advanced technology and the freedom to explore, experiment and innovate. Our strength lies in independence, reliability and collaboration. We find each other in wonder and ingenuity. We are driven to push boundaries. By working with businesses and government, and by connecting different perspectives, we strengthen our innovative capability and create responsible, meaningful results.

At TNO, we believe this is our time to help society, government and business move forward faster. Together with driven colleagues, you turn knowledge into concrete innovations or ventures that truly make a difference by combining the power of science and entrepreneurship. And in doing so, you make your mark on our time.

The selection process

Please apply before the 22rd of August, 2026. The selection process comprises two interview rounds. We aim to finalize the entire process within four weeks.

The selection process may include an online assessment and a reference check.

As you will be working for clients in the domain of defence and security, a Certificate of No Objection issued by AIVD (the Dutch General Intelligence and Security Service) is mandatory. This means you will have to undergo a security screening. Read more about security screening
