Working at ORTEC
ORTEC is an ambitious organization. Since our founding in 1981, we have grown to employ over 1000 people at locations in Europe, the United States, Australia and Brazil. Most of our employees began working with us after completing their studies. The average ORTEC employee has a technical master's or bachelor's degree, a strongly developed capacity for analytical thinking and the drive to understand problems and then to solve them. The company’s organizational structure is flat, with short lines of communication. The atmosphere is open and informal, which forms an excellent basis for a productive working environment.

You are invited to attend social activities organized by our employees' association, and the Friday afternoon drinks in our own ORTap. Furthermore, an excursion for your department or ORTEC as a whole is organized annually, such as the Christmas breakfast or a barbecue at one of the founders’ homes. And in addition to the (Young) Professionals Development Program, each month Young ORTEC organizes activities to help develop your talent, increase your knowledge and expand your network.

Students and starters
We are always looking for ambitious students/starters who have affinity with IT, optimization and logistics. There are different possibilities for students. As a student you can do a graduation internship and/or work part-time as a student assistant.

If you are interested in working at ORTEC, you can send your resume, motivation and grades list to recruitment@ortec.com. Give a clear indication about the period and specialization you are looking for in the (graduation) internship or part-time job. For more information you can contact Anouk de Winter or Larissa Ravenhorst (Recruiters).

Master (thesis) internship: Computing shortest paths & machine learning in route optimization

Computing shortest paths in graphs is essential in ORTEC's routing software. Before operational plans can be created in industries such as parcel, e-grocery, or field service, it is necessary to know the best routes between all considered addresses. Finding these best routes involves several layers of complexity, as the time and distance travelled are affected by factors such as the time of day, traffic jams, road blockages and different types of vehicles.

To find these routes ORTEC uses cutting-edge algorithms focused on accuracy, speed, stability, and scalability. We also employ machine learning models that use customer data to predict realistic travel times.

We continuously strive to improve these models and to stay up to date with academic insights. We are therefore very eager to work with a talented master’s student on a thesis and/or as a student assistant. We have several suitable thesis topics available and will discuss our ideas with you to find a topic that excites both you and the team. Examples include, but are not limited to, studying the effect of the current traffic situation on the estimated travel time and investigating alternatives to (elements of) our current shortest path algorithm.
After studying the academic literature on this topic, you will address it by developing a new model, algorithm, or tool, or by extending our existing ones. Finally, you can test your approach using real-life data. During this process, you will be supported by an ORTEC supervisor who is part of the team working on computing shortest routes.

• You are studying for a master's degree in the field of computer science, operations research, mathematics, machine learning, or other similar areas.
• You are curious and like to get to the bottom of a problem.
• You have experience with traditional operations research algorithms and problems, such as metaheuristics, local search methods and/or routing problems.
• You have work/academic experience where you independently built working applications, prototypes, or proof of concepts.
• You have good coding skills (preferably OOP) in at least one programming language and enjoy optimizing your code (e.g. speed, memory usage, multi-threading).
• You can communicate fluently in English, verbally and in writing.
• You are available for a minimum of six months.

• Join our company and improve the world
• Enjoy an open, kind and fun culture with the possibility to work partly remote.
• Active employee association with fun activities with colleagues
• We help you to #stayhealthy, to #stayeffective and to #stayconnected: we organize both online and offline activities such as pub quizzes, online sports events, social calls with colleagues, and more.
• Excellent supervision during your project from your supervisor (Manager Corporate Communications) and the rest of the team.
• Good internship allowance and a laptop
• Activities with all graduate students at ORTEC, like Friday afternoon drinks
