Welcome to Koning & Hartman!

We provide a warm welcome with our onboarding programme.

‘The great thing about working at Koning & Hartman is that every day brings something new. Your colleagues are there to help you make it a success together!’

‘I have been working at Koning & Hartman since September 2024 and not a single day has been boring. This means that I enjoy going to work every day and stay motivated!’

‘It used to be a niche market, but nowadays you can't do without “Assemblage”. We continue to develop, which keeps the work interesting.’

‘If you had told me that I would be working at Koning & Hartman for 25 years, I would never have believed it, but now, 25 years later, I'm still here!’

In our network organisation, we work together in varying configurations that transcend brands and teams. Why? To always be able to offer our customers added value. That is why we act on the basis of a common set of values: the VINCI Energies way of life. This way, we know what we can expect from each other, we avoid misunderstandings and we achieve the best results, both individually and collectively. It determines our behaviour, gives us conviction and strength, reinforces loyalty and provides direction.

Giving people space for freedom and initiative so that every employee and team can get the most out of themselves. It is not independence, but more than just simple authority.

Trust is the foundation of all relationships and takes precedence over control
Trust is a prerequisite for good working relationships. Openness is necessary for trust; without transparency, our network cannot function.

Actively contributing to common goals and working together is extremely important within your teams, our network and our organisation. The importance of the whole is paramount. It's all about team spirit: you want your colleagues to succeed, and shared success is double success.

Taking responsibility for your actions towards your colleagues, customers and projects. Working alone or with others, setting goals and giving them shape and substance. Being given and taking the space to develop activities and offer value.

Every employee is capable of seeing opportunities, taking initiative, getting the most out of themselves, identifying opportunities, assessing risks and achieving success.
