Skills: MRI Physics, RF Engineering, Pulse Sequence Programming, Signal Processing, Electromagnetics
Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and build custom MRI hardware, including RF coils and gradient systems, for biological experiments. Develop pulse sequences and signal analysis pipelines to extract biophysical data from MRI signals.
Seeking a first-principles thinker with experience in MRI physics, RF engineering, or quantitative imaging. Candidates must be comfortable building physical systems and working across multidisciplinary domains like biology and electromagnetics.
Our mission is to bring aging under full biomedical control. We believe this can be achieved through closed-loop hardware that reads and writes bioelectric states in living tissue using electromagnetic and acoustic fields – a control layer for cell reprogramming that chemistry and gene therapy fundamentally cannot provide.
We're looking for exceptional engineers to join us in building machines that make aging optional.
As an MRI Engineer at AION, you will:
Design and build custom MRI hardware for experiments across cells, tissues, animals, and eventually humans
Work directly with scientists to translate informal experimental needs into functional imaging systems, fixtures, coils, sequences, and analysis pipelines
Design, fabricate, and test RF coils, gradient systems, low-field magnet assemblies, shielding, phantoms, sample holders, and bench-scale MRI hardware
Develop and optimize pulse sequences for low-field and experimental MRI, including approaches for relaxation mapping, diffusion, susceptibility, flow, and quantitative tissue-state imaging
Build reconstruction and signal analysis pipelines to extract biophysical data from MRI signals: T1, T2, T2*, diffusion metrics, conductivity-adjacent signals, phase, noise, drift, and field inhomogeneity
Close the loop between hardware and biology: design the scan, build the system, acquire the data, analyze the signal, and make the tool practical for scientists to use
Survey and prototype emerging MRI modalities: low-field MRI, portable MRI, magnetic resonance fingerprinting, quantitative MRI, MR elastography, electrical properties tomography, and hybrid electromagnetic imaging systems
We value mission alignment, integrity, and ambition over pedigree.
Strong first-principles thinker who is comfortable working with teammates outside your own domain
Generalist wiring: willing to learn across electromagnetics, hardware, biology, signal processing, and experimental design
Comfortable building real systems, not just simulations or papers
Experience with MRI physics, RF engineering, gradients, magnets, pulse sequence programming, reconstruction, or quantitative imaging is valuable, but obsessive technical ownership matters more
