Arthur Senior Business Developer

A few months ago, I made a list of characteristics of the ideal company I would like to work with: – human-sized – focused on optimization technologies – fully dedicated to client success – developing an innovative optimization solver offering a unique blend of expressiveness, simplicity, performance, and robustness – powered by a young and creative team constantly thinking out of the box Hexaly checks all the boxes. Thank you, Frédéric Gardi, Thierry Benoist, and the entire team for giving me the opportunity to be part of this great adventure. I am thrilled to join you!

Philippe Senior Optimization Scientist

I chose to join Hexaly to tackle top-level scientific challenges that arise when developing an optimization solver. Now I am glad to be part of a wonderful and highly skilled team! I am currently focusing on improving the solver performance, and I am also developing customized solutions for several of our clients, such as Air Liquide, RTE, or SNCF.

Guillaume Optimization Scientist

After my first experience as a Partner Sales Executive at Microsoft, Hexaly commercial development is a new challenge. I like the idea of meeting customer needs with innovative solutions.

Inass Business Developer

Adrien Optimization Scientist

I was looking for a new challenge in the technology industry, and Hexaly seemed like the perfect opportunity. The support I received during my first days allowed me to become proficient at my job quickly. Today, I have the pleasure of helping our clients solve their most complex problems in an enjoyable work environment.

Aurélien Customer Success Manager

During my six-month internship at Hexaly, I worked on improving the solver’s performance on Vehicle Routing problems. Working with this wonderful and highly-skilled team has allowed me to discover new techniques to tackle challenging optimization problems. I am glad to keep working here and improving my skills while developing our solver.

Bienvenu Optimization Scientist

I was immediately seduced by this job which allows me to work on the R&D of the solver and optimization projects for clients. This organization allowed me to gain new skills quickly!

Emeline Optimization Scientist

After spending three years doing research work at Hexaly, I recently got to (successfully) defend my Ph.D. thesis. During these three years, I worked on improving the solver's performance on various kinds of scheduling problems, as well as on making them easier to model for our users. It was very rewarding to see my Ph.D. work being gradually integrated into the successive commercial versions of Hexaly. I am now glad to continue working here and to keep developing state-of-the-art algorithms to make our solver ever more efficient.

Léa Optimization Scientist

It is amazing to learn about exciting topics through my job constantly. I have the opportunity to work on advanced mathematical subjects as R&D for the optimization solver and various industrial-sized projects with companies like Air Liquide, RTE, or Haensel AMS.
