Paris, France Nabla Temps plein

Context Karavela is a neuroscience research company established in 2025 and currently based in Paris, France. We build a foundation model of the human brain relying on nextgeneration magnetic resonance. To do so, Karavela is collecting a very large MRI dataset from healthy volunteers listening to naturalistic stimuli (e.g., audiobooks, podcasts, radio programmes). This dataset is then used to train deep learning models that can reconstruct the stimuli from recorded brain activity. The goal is to leverage the representations learnt by these models in downstream applications, in particular by providing biomarkers for neurological and psychiatric diseases in clinical trials. Karavela is currently organised into 3 teams that each focus on one of the aforementioned aspects: data collection, model development, and clinical applications. Position summary Karavela collects image and raw k-space data to train its brain decoding models, with the intent of complementing historical image-reconstruction objectives with new types of signals and push the limits of MRI acquisition. We are looking for an MRI physicist to lead the development of new MRI sequences that will be optimised for brain decoding purposes (with a focus on high SNR and temporal resolution), using pulseq. Sequence parameters will eventually be evaluated regarding the level of accuracy they achieve. In this role, you will be interacting with the data collection and model development teams. Qualifications The ideal candidate will have: MS or PhD in MRI physics, or a related field; strong experience in MRI sequence development, preferably with pulseq; knowledge of MRI hardware and software, particularly Siemens scanners; excellent problem-solving skills and ability to work in a collaborative environment; basic knowledge of machine learning; strong communication skills, both written and verbal. Benefits This position offers: open-ended contract (CDI); Competitive compensation, depending on experience; equity options; 25 days of paid time off per year; full-time position in Paris, partial remote work is possible. #J-18808-Ljbffr
