Responsibility. From conception to series production.
At RATIONAL we take a special approach: a holistic approach to product development. What does this mean? Instead of working on the same tasks over and over again, you will be responsible for a specific function - such as electrical steam generation - and you will accompany it from the initial idea through to market maturity. This process allows you to immerse yourself in your projects and take responsibility for the big picture. You will see first-hand how your ideas inspire our customers and can actively drive improvements. Your input is not abstract. You can see the success of your work in direct feedback and in the real-life use of our equipment. At RATIONAL we work in agile teams that are passionate about innovative solutions. Our holistic development approach gives you real responsibility and the chance to significantly influence the development process. You won't just have a job, you'll be shaping the future of kitchens worldwide.
Application research and development
As a food technologist or nutritionist in applied research and development, you will be working on the really important things, such as the perfect roast pork or delicious croissants. Working with specialists in mechanics, control engineering and software, you will develop practical products and study cooking methods and foods from all over the world. This is where experimentation and learning go hand in hand.

Cooking smarter.
At first glance, our lab looks like any other development department. The big difference: It has the tantalising aroma of fresh croissants. And whether the iCombi Pro's cooking intelligence is working as it should is checked by the objective eye of our experts. We measure, weigh, taste and compare. Because research into the traditional French pastry is not a purely mathematical problem. This means we cook, and we cook a lot. We ask ourselves what happens in a food and how humidity, temperature and cooking time affect it. We have been incorporating this knowledge into our cooking systems for over 50 years!
What cooking and magic have in common.
It's a magic trick that our RATIONAL cooking systems perform perfectly: The chef inserts a raw piece of beef, selects the appropriate programme and a few minutes later a steak comes out perfectly browned, with appetising grill marks and a delicious aroma. Magic or science? Perhaps both! The key lies in the chemistry: Sugars and amino acids react with each other on the surface of the meat in what is known as the Maillard reaction. Hundreds of molecules are created: Some give the typical roasted flavour, others the delicious aroma, and then others the brown colour and grill marks. Well researched scientifically, but still fascinating. Thanks to iCookingControl, our cooking systems make the most of this knowledge to guarantee perfect roasting flavours, colours and tastes. No witchcraft - or maybe a little!
Software
In the software department at RATIONAL, you're right in the middle of things. Here you'll not only program hardware-related software, but you'll also be able to see what you've created directly on the device. Our developers and testers work closely together to ensure that all the gears mesh perfectly. Specially developed algorithms in the Linux operating system are combined with our own hardware and years of cooking research. They help develop new features, always with the aim of making our cooking system even better, faster and easier to use. In this way, you will directly contribute to our customers' enjoyment of our product.
