ML Research Scientist

Senior ML Research Scientist (probabilistic inference) Montreal We are seeking a senior machine learning (ML) researcher to join our team working on a novel AI safety research agenda. In this role, you will develop and evaluate probabilistic inference methods, with a focus on amortized inference, translating theoretical insights into practical implementations. Key responsibilities Develop amortized inference methods suitable for high-dimensional discrete and continuous distributions. Develop parameter- and structure-learning methods for large probabilistic graphical models that benefit from amortized probabilistic inference. Design evaluation strategies for GS methods that rely on probabilistic inference. Collaborate with mathematicians on theory related to learning and inference in probabilistic models. Translate theoretical proposals into high quality implementations in a programming language such as Python. Analyze and interpret experimental results to steer future research directions. Communicate complex findings effectively to various stakeholders. Skills and qualifications Advanced degree in a relevant field (e.g., Computer Science, Mathematics). A PhD is preferred but not required if the candidate demonstrates exceptional abilities. A minimum of 3 years of experience in deep learning research. Expertise in probabilistic inference is required, in addition to expertise in one or more of the following:Amortized inference methods (including GFlowNets) Sampling-based approximate inference methods Bayesian inference Parameter- and/or structure-learning in probabilistic graphical models (including causal models) Strong background in mathematics. Proven experience in developing and implementing machine learning models. Proficiency in programming languages such as Python, and experience with ML frameworks like PyTorch or TensorFlow. Excellent analytical and problem-solving skills, with a demonstrated ability to think critically about complex systems. Strong communication skills, both written and verbal, with the ability to explain complex ideas to diverse audiences. Track record of contributing to high-quality research in probabilistic inference or related fields. Ability to work collaboratively in a team environment while also being self-motivated and independent. What we offer The opportunity to contribute to a unique mission with a major impact. A minimum of 20 days vacation per year upon start. A minimum retirement savings employer contribution of 4%. Generous flexible benefits designed to contribute to your well-being.
