As a member of our R&D teams, you will apply your digital skills in the field of operations research to design and develop cutting-edge optimization solvers.

You will often have the opportunity to work on various types of digital libraries developed by Artelys: continuous and mixed nonlinear programming (Artelys Knitro), constraint programming (Artelys Kalis), optimization of energy systems (Artelys Crystal Optimization Engine).

You will be responsible for developing new algorithmic features combining mathematics and computer science, while striving to maintain a high level of software robustness and performance.

Depending on the projects, the solutions developed may fall into three different frameworks:

• Numerical and combinatorial optimization software developed by Artelys, in particular  Artelys Knitro,  Artelys Kalis , Artelys Crystal Optimization Engine,or PowSyBl Open Load Flow
• Computation modules for one of our clients
• Prototypes within research projects in which Artelys is involved

Holder of a PhD in applied mathematics or operations research, or have equivalent experience of at least 3 years after obtaining an engineering degree or higher education qualification, you are the ideal candidate if:

• You have proficiency in Python or C/C++ programming language
•  You have expertise in various optimization methods: graph theory, continuous optimization algorithms, combinatorial optimization algorithms, nonlinear optimization, etc.
• You have proficiency in designing and optimizing algorithms for high performance computing (HPC) environments
• Fluency in English. French is a plus

Following skills are a plus:

• You have additional knowledge in software programming (Spring, BDD, NoSQL, REST/Microservices, Message queuing, etc.) and in compilation
• You are proficient in other programming languages (MATLAB, R, Julia, Java, C#)
•  You are proficient in linear algebra tools (especially methods for solving linear systems)
• Previous contributions to open source projects related to numerical optimization, simulation, or computational science would be highly valued. Active participation in relevant communities and networks is appreciated

Curious and enthusiastic, you enjoy tackling complex problems and aspire to develop high-performance, innovative software tools based on cutting-edge mathematical methods. You also demonstrate a high level of rigor in the work you undertake. You aim to contribute to creating a work environment where everyone can develop their skills and initiative.

Working conditions:

• Permanent contract, managerial status with a 4-month probationary period.
• Up to 2 days of remote work per week possible.
• Flexible working hours.
• Offices located in the city center of each city where we are located

Recruitment process:

Step 1: An initial technical interview via video conference with two recruiters (45 minutes x 2).

Step 2: A second interview via video conference with two other recruiters, as well as a brief 15-minute discussion with the CEO of Artelys (45 minutes x 2 + 15 minutes).

Step 3: If your interviews are successful, we will invite you to visit our premises to make you an offer in person and introduce you to the work environment.
