Computational MRI Physicist

At AION, we’re building sci-fi medical devices. Our mission is to bring aging under full biomedical control. We believe this can be achieved through closed-loop hardware that reads and writes biological states in living tissue using electromagnetic and acoustic fields. We're looking for exceptional scientists and engineers to join us in building machines that make aging optional. The Role As a Computational MRI Physicist at AION, you will: Build the computational layer that turns raw MR signals into quantitative measurements of tissue stateDevelop physics-based models and simulation tools for our low-field, single-sided MRI systemsDevelop reconstruction and parameter-estimation methods for T1, T2, diffusion, proton density, and other quantitative tissue propertiesDesign acquisition strategies that maximize biological information per unit of timeBuild methods for uncertainty estimation, calibration, and longitudinal measurementWork directly with MRI engineers and biologists across simulation, hardware, and biological experimentsAdvance quantitative MRI, MR fingerprinting, field-cycling relaxometry, and model-based reconstruction You We value mission alignment, integrity, and ambition over pedigree. Strong first-principles thinker across physics, mathematics, software, and hardwareDeep intuition for MRI physics, inverse problems, and quantitative measurementStrong scientific computing, signal processing, and numerical optimization abilityExperience with quantitative MRI, reconstruction, computational imaging, or related fieldsComfortable moving quickly between theory, simulation, and experimental systemsExceptional technical ownership and willingness to work on hard, unsolved problems Details St. Louis, MO (on-site).
