(H/F) AI & Control Senior Engineer - Modeling & Simulation

Wandercraft is hiring!

About

Chez Wandercraft, nous concevons, fabriquons et vendons des robots dont la mission est d’aider les humains à faire ce qu’ils ne peuvent pas faire. Nous mettons en oeuvre les technologies d’AI et de robotique les plus avancées dans les métiers de la santé et de l’industrie.

Atalante X, le premier exosquelette de marche autonome au monde, est utilisé dans plus de 100 centres de rééducation sur 4 continents, et permet à des patients qui ont perdu la marche de ré-apprendre à marcher. Avec Atalante X ils font plus d’un million de pas chaque mois.

Après plus de 10 ans sur le terrain et des milliards de pas analysés, nous lançons Eve, le premier exosquelette personnel auto-équilibré, pensé pour aider les utilisateurs en fauteuil roulant à se lever et marcher dans leur vie quotidienne, chez eux et dans la ville.

Enfin, nous commençons à appliquer notre technologie dans l’industrie, avec la gamme de robots humanoïdes Calvin. Calvin-40, notre premier modèle, a été conçu en 40 jours pour soulager les opérateurs en usine des tâches pénibles ou dangereuses. Bientôt une évolution de Calvin accompagnera des personnes avec une autonomie réduite dans leurs gestes quotidiens.

Depuis Paris et New York, notre équipe de 110 ingénieurs, cliniciens, chercheurs et opérateurs est unie autour d’une même mission : concevoir des robots qui améliorent la vie des humains.

Ce n’est pas une simple équipe que nous assemblons : c’est une aventure portée par des esprits curieux, engagés, des pionniers prêts à construire un futur qui a du sens.

Envie de rejoindre l’aventure ? Viens façonner avec nous la prochaine génération de robotique humanoïde, alimentée par l’IA et guidée par l’humain.

Our AI & Control Team is growing to meet new challenges!

Wandercraft develops advanced bipedal robots designed to operate safely and robustly in the real world. Simulation plays a central role in this effort: it allows us to design and validate control strategies, prototype new behaviors, and accelerate robot development before deploying algorithms on hardware.

In addition, since 2025, Wandercraft has been venturing into humanoid robotics in close collaboration with the Renault Group. Building on our expertise in bipedal robotics, we are expanding our capabilities in autonomy, manipulation, and large-scale experimentation. High-fidelity and scalable simulation environments will be a key enabler for these developments.

To support these ambitions, we are strengthening our simulation capabilities. The Senior Modeling & Simulation Engineer will play a crucial role in designing, developing, and evolving our simulation environment. This environment will support control development, large-scale experimentation, and machine learning workflows, enabling faster iteration and more reliable testing of our robotic systems.

The engineer will be integrated within the AI & Control department and will work closely with other members of the team. Simulation is a core tool used across many of our developments, and this role will collaborate regularly with other R&D teams, including embedded software, electronics, and mechanics.

In this role, you will contribute to improving the realism, robustness, and performance of our simulation tools. You will help develop new simulation capabilities, support large-scale experimentation for machine learning and control algorithms, and evaluate emerging simulation technologies relevant to robotics. Your work will play a key role in bridging algorithm development and real-world robotic deployment.

Reporting to Controls, Architecture, Product, Simulation team, the Senior Modeling & Simulation Engineer will be in charge of (non-exhaustive list):

  • Develop and evolve the simulation environment to improve physical realism and model fidelity

  • Optimize simulation performance and scalability to enable large-scale testing and learning campaigns

  • Develop, implement, and run parameter identification methods to improve the accuracy and predictive power of simulation models

  • Develop and apply methods to measure, analyze, and reduce the sim-to-real gap between simulated and real robotic systems

  • Design and implement new simulation capabilities based on the needs of the control, robotics, and machine learning teams

  • Maintain and evolve the simulation platform (software infrastructure, tools, and pipelines)

  • Collaborate with the control and machine learning teams to facilitate the use of simulation for algorithm development and validation

  • Conduct technology watch on methods, tools, and simulation engines relevant to robotics

  • Identify, evaluate, and benchmark new simulators or simulation frameworks

  • Lead the integration of new simulation engines into the control architecture

Preferred Experience

  • Diploma: Master’s Degree / PhD

  • Required experience: 5+ years in robotics, simulation, or a related field

    Academic experience will be valued, particularly in relation to robotics simulation, physical modeling, machine learning, optimal control, or related fields.

    Creativity, innovation: you are able to develop new things with a limited existing base and to make prototypes (personal or professional robotics projects are highly appreciated).

    You have an interest in experimentation and adapting algorithms and tools to the constraints of real systems and commercial robotic products.

    You have experience in software development (Python/C++).

    You have experience in team software development (modularity, responding to specifications, continuous integration, etc.).

    You are comfortable with linear algebra (matrix calculations), kinematics, and physical modeling (reference frame changes, dynamics, contact modeling, etc.).

    Experience with robotics simulation tools or physics engines (e.g., MuJoCo, Isaac Sim, Gazebo, Drake, Bullet, etc.) is a strong plus.

    You are rigorous, able to proofread your work and explain your models, calculations, or algorithms clearly.

    You are curious and have good analytical skills, enabling you to monitor technological developments effectively and learn from scientific literature or meetings at conferences.
