Join TU Delft and the EU-funded OPERA consortium. Push the frontier of general-purpose AI for robotics and tackle the fundamental tension between long-horizon reasoning and real-time safety guarantees.
Job description
Robots that operate for long periods among people must plan beyond the next few seconds while staying safe. They need to predict how their surroundings and the people in them will evolve, know how reliable these predictions are, and adapt their plans when the predictions fail. In the EU-funded OPERA project, TU Delft contributes to General-Purpose AI for robotics by developing methods that combine fast, reactive behavior with more deliberate reasoning, planning, and decision-making.
In this PhD position, you will develop planning and decision-making methods that let robots act safely and reliably over long time horizons when their knowledge of the environment and of the people around them is incomplete. The research sits at the intersection of model-based planning and control and learning-based models, and addresses the trade-off between safety, performance, and real-time computation. You will formulate the methods and analyze their guarantees and failure modes. This research is connected to OPERA's tasks on GPAI-powered planning and decision-making, on long-term reasoning in human-centered environments, and on adaptive human-robot and robot-environment interaction.
Depending on your background, the work may draw on optimal control and model predictive control, motion planning, probabilistic modeling and estimation, or learning-based methods. The emphasis is on methods with a clear formulation and well-understood failure modes, validated in simulation and on real robots.
You will work in the Cognitive Robotics Department at TU Delft under the supervision of Prof. Robert Babuška and Dr. Laura Ferranti, and you will be embedded in the Reliable Robot Control Lab ( You will collaborate with OPERA partners across Europe on simulation, perception, and the OPERA open-source toolbox.
Job requirements
The ideal candidate for this PhD position has a strong background in control, optimization, or motion planning and is motivated by the question of how robots can plan safely and reliably over long time horizons. We welcome applicants from all backgrounds who want to work at the intersection of planning, control, and learning.
You have:

An MSc degree in Systems and Control, Robotics, Applied Mathematics, or a closely related field.

A strong interest in safe planning and decision-making for robots, at the intersection of planning, control, and learning.

A passion for rigorous, theoretically grounded research, combined with an eagerness to validate ideas in simulation and on real robots.

Strong analytical and mathematical skills, in particular in optimization, probability and statistics, and dynamical systems.

Excellent communication skills and proficiency in English (written and verbal), as required for academic publication and international collaboration.
You are particularly encouraged to apply if you have experience in one or more of the following areas:

Hands-on experience implementing optimization-based planners or controllers (e.g., model predictive control with acados or CasADi) in C++ or Python.

Safe or robust control and planning under uncertainty.

Learned dynamics or prediction models, model-based reinforcement learning.

Uncertainty quantification, probabilistic or Bayesian modeling, state estimation.

Long-horizon or hierarchical planning, prediction of human or multi-agent behavior.

Real-robot deployment with ROS or ROS 2.
As part of OPERA, you will travel to meet and collaborate with the project’s European partners and attend regular consortium meetings.
We particularly encourage applications from women and other underrepresented groups, as we are committed to building a diverse and inclusive research environment.
TU Delft (Delft University of Technology)
Working at TU Delft means contributing to solutions that really make a difference.
For over 180 years, we have been training engineers who make an impact worldwide in companies, government bodies, or as entrepreneurs. Our alumni turn knowledge into concrete solutions for the challenges of today and tomorrow. These challenges are changing rapidly. That is why we focus on themes such as energy, climate, digitalisation, artificial intelligence (AI), and smart mobility every day. Our education and research are directly aligned with what society needs now and in the future.
At TU Delft, our people make the difference. With their knowledge and curiosity, our staff provide a high-quality education and conduct pioneering research that extends beyond the campus. You will have the opportunity to take the initiative, work with others, and grow as a professional. Working at TU Delft means join an international community of professionals and students. Together, we create knowledge, innovations, and solutions that help move the world forward.
Faculty Mechanical Engineering
From chip to ship. From machine to human being. From idea to solution. Driven by a deep-rooted desire to understand our environment and discover its underlying mechanisms, research and education at the ME faculty focusses on fundamental understanding, design, production including application and product improvement, materials, processes and (mechanical) systems.
ME is a dynamic and innovative faculty with high-tech lab facilities and international reach. It’s a large faculty but also versatile, so we can often make unique connections by combining different disciplines. This is reflected in ME’s outstanding, state-of-the-art education, which trains students to become responsible and socially engaged engineers and scientists. We translate our knowledge and insights into solutions to societal issues, contributing to a sustainable society and to the development of prosperity and well-being. That is what unites us in pioneering research, inspiring education and (inter)national cooperation.
