What is your ambition?  We’d like to know, because we make your ambitions our business.  And if you have ambitions as a financial and administrative assistant, helping you achieve them is what we do best.  Join our team to develop your strengths and enjoy a fulfilling career full of varied experiences.

What this job involves  

You’ll endorse the administrative responsibility of the fitting out projects. You’ll therefore work in close collaboration with the Project Managers, in charge of the client and responsible for following up the fitting out of projects. Your main working tool will be our specific software, Tetrisoft, which you will of course be trained to use internally.  

Your tasks will include, among others, working out quotations based on the instructions of the Project Managers; the financial & contractual management of all project revenues/ expenses; the follow-up and control of client and supplier billing. 

Though this will be the most important part of your job, you’ll also endorse other general administrative tasks like translations, filing, presentations, etc. 



You’ll hold a bachelor degree as management assistant or have experience in a similar function. 

You’ll have good knowledge of French, Dutch and English, both written and spoken.  

​Numbers & IT-Literate

You have an interest for figures as you will manage the financial side of projects with accuracy and provide diverse reporting with our dedicated tools.  However, academic accountancy knowledge is certainly not required therefore.

We’ll expect you to have knowledge of MS Office, including excellent control of Excel. 


Being rigorous and having good organizational skills is vital for this position.


You are a proactive person, ready to carry out your own tasks autonomously.

Most importantly, you’ll want to work as part of a supportive and talented team.  ​

Required Qualifications

​You’ll join an entrepreneurial, inclusive culture.  One where the best inspire the best.  Where like-minded people work naturally together to achieve great things.

Join us to develop your strengths and enjoy a fulfilling career full of varied experiences.  Bring your ambition and explore a world of possibility.
