I joined FFT 20 years ago, when it was a 3-person start-up, and helped it grow to a 50-person independent business unit, part of a large multinational company, with many new opportunities, especially in terms of technical collaborations. My job consists in solving real-life industrial challenges, using the right numerical methods found in the latest scientific literature, but also conducting applied research, purely internal or in collaboration with academic research groups. The stimulating and challenging research, together with the nice work environment and great colleagues, explains why I happily stayed at FFT all those years.

G. Lielens, Manager Research & Development Free Field Technologies Belgium


I have been working at FFT for 12 years now. I am part of the development team, focusing on the user interface. As Validation and QA Manager, my role is to ensure the quality of our software and all new developments. I have the chance to work on a wide array of subjects and applications that cover a large range of physics and are used by a variety of customers. Every new development brings unique challenges and opportunities of improvement, and there is always room for new ideas and initiatives at FFT.

B. Van Antwerpen, Validation & QA Manager Free Field Technologies Belgium


I joined FFT in 2017, coming from a very different field, and immediately felt that I was part of a team working towards a common goal of excellence. As a Product Development Engineer, the core of my work consists in continuously improving the software to ensure that it meets our clients needs. Regular interactions with the support team are another part of my job, mainly during the specification and validation phases of developments. I really appreciate working on a cutting-edge technology with competent, motivated and respectful colleagues.
