What will be your role?

Energy-neutral, sustainable buildings and optimal indoor air quality for safe living and working. These are major challenges that also face the healthcare sector and will require a lot of work. There are already many innovative ways to make buildings sustainable, but which are suitable for the healthcare sector? What options pose the fewest risks to the care process? What additional requirements do you have to take into account with buildings that are in operation 24/7? What is the ideal combination of installations and what is the optimal set-up for these installations? And how do you make this affordable for the healthcare organisation and ensure that it fits within the government’s macro frameworks?
The issue of good indoor air quality is high on our agenda. Examples are air treatment in operating theatres to minimise infection risks, or air conditioning and ventilation to create a healthy environment for patients and staff.

As a scientist for energy transition and indoor air quality, you’ll be working on solutions to these issues. In this way, you’ll make a real contribution to enhancing the sustainability of the building stock in general and healthcare property in particular!

Data-driven modelling of the performance of buildings and installations will be an important methodology in your work. Digital twinning is a technique that we are using increasingly in this context. Using a digital copy of the building or installation, we can convert measurement data into information for optimisation. By developing physical models and linking them to real-time and other data, you’ll analyse the performance of buildings and installations, and translate the resulting data into useful information for the client. You’ll enable innovations to improve energy use and the indoor environment, for example with self-learning installations and predictive maintenance, or intelligent buildings with guaranteed performance. You’ll also work with Dutch and international stakeholders on developing related innovative products that could accelerate the energy transition.

You’ll be working in the Healthcare Assets team of the Building Physics & Systems department. This close-knit team of about six colleagues – advisors and researchers – works on issues at the interface between architectural and installation issues, and the primary process in healthcare buildings. In addition to improving sustainability and indoor air quality, we also deal with the safety of buildings for patients and other users, but also with the question of how many healthcare buildings we’ll actually need in the future and where they should be located. The atmosphere in the team is informal and we find it important for everyone to feel at ease; we regularly do something fun as a team or get together for a drink.

How do you want to contribute to tomorrow's world? How big can your impact be? Come and work at TNO and envision it.

What we expect from you

You enjoy working in a team and you’re keen to learn. You have a feel for multidisciplinary collaboration, but you also have no problem tackling tasks independently. You have strong analytical skills, so that you’re able to translate physical and other processes in utility buildings into models. You’re adept at drafting research questions, research plans and research reports, and you have good communication skills. Your clients will mainly be Dutch, but many of your TNO colleagues speak English. You should therefore have an excellent command of both languages.

To be a good fit for this position, it is important that you recognise yourself in the following profile:
  • You have a university degree in the field of mechanical engineering, physics, architecture or technical physics;
  • You’re enthusiastic about sustainability in construction and the energy transition in the built environment in particular;
  • You have an affinity for data and modelling for your field. You enjoy the challenge of setting up physical models and linking them to sometimes complex data. Experience with packages such as Python or C++ and a basic knowledge of statistics are an advantage. Very important: you can clearly explain what the models do and what they calculate to people who are less familiar with them;
  • You have a good command of spoken and written Dutch and English;
  • You’re well aware of the challenges facing the construction and technology sector. This enables you to identify research and development opportunities together with the team.
  • Being a researcher with the Healthcare Assets team means dealing with much more than just technology. The team works in a complex environment where we have to take into account the interests of many different stakeholders. In our projects, we collaborate with public authorities, healthcare organisations, suppliers and technical experts. Successfully implementing solutions is at least as important – and at least as complicated – as technological innovation. This requires the team to operate diplomatically and not only to validate solutions technically but also to test them against the wishes and requirements of the client and other stakeholders, such as the central government. If you join the Healthcare Assets team, it’s important that this appeals to you and that you’re prepared to invest energy in getting to know the field of activity and developing your talents in that field.

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 € 2,900,- and € 3,700,- (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:
  • A good pension scheme.
  • Travel allowance or a bike [OPTIONAL] or a leased car.
  • Possibility of a permanent contract.
  • An extremely professional, innovative working environment where colleagues are leading experts in their field.
  • 28 days annual leave and 5 compensation days under the reduction in working hours scheme (ATV, arbeidstijdverkorting) on a full-time basis.
  • 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 and the possibility of working from home.
  • The opportunity to attend courses, workshops and conferences, and to receive training and coaching based on your needs.
  • Access to our Talent Development Programme.
  • Networking opportunities and great activities organized by Jong TNO.
  • Extensive relocation package for international candidates.
