AI Engineer (Always Open)

Chipiron is building a radically new generation of MRI systems.

We are taking one of the most complex medical technologies in existence and trying to make it radically simpler, cheaper and more accessible.

We have no shortage of hard problems to solve. What we're looking for is exceptional people capable of solving them.

We don't believe great talent should have to wait for an open position. If you're among the best at what you do, have a bias for action, and want to build technology that has never existed before, we'd like to meet you.

Who we're looking for Your background matters much less than your trajectory. You probably recognize yourself in several of these:

• You are exceptionally good at what you do, and you can show it
• You reason from first principles, not from what already exists
• You take ownership beyond your formal responsibilities
• You hate letting problems sit unresolved
• You make decisions with incomplete information
• You communicate directly, including when you think we're wrong

Key Responsibilities

• Push the boundaries of AI-powered medical imaging. Explore and develop state-of-the-art approaches to MRI image enhancement, super-resolution, and reconstruction, including diffusion models and other generative techniques.
• Own AI development from research to deployment. Design, implement, optimize, and deploy models that deliver measurable improvements in image quality.
• Solve challenging image-processing problems. Develop robust approaches to image registration, alignment, and deformation across MRI scans acquired at different field strengths.
• Build the foundations for high-performing AI models. Create, curate, and leverage imaging datasets, working with internal teams and external partners to overcome data limitations.
• Prove that your models work. Define meaningful evaluation metrics, rigorously validate performance on synthetic, phantom, and patient data, and translate research into reliable solutions.
• Work across disciplines to deliver real-world impact. Collaborate closely with MRI acquisition, sequence development, reconstruction, and other engineering teams to integrate AI into our imaging pipeline.

Who We Are Chipiron is a French startup that is leveraging the emerging properties of ultra-low magnetic fields (<30mT) to build the first light, inexpensive MRI machine without compromising on image quality. We're a team of engineers based in the heart of Paris, and our mission is to revolutionize the medical imaging industry by developing the first plug-and-play, patient-friendly breast MRI that works everywhere.

Our Culture We are an international, English-speaking team that values technical excellence, interpersonal intelligence, and engagement. At Chipiron, this means we look for people with exceptional analytical ability, who enjoy mastering complex problems and executing with rigor and precision; communicate clearly and concisely, are self-aware and willing to ask for help and to help others when needed; people who go the extra mile, and instinctively move where impact is highest, rather than staying confined to a job description.

This is an always-open opportunity, not necessarily an active vacancy. We review applications on an ongoing basis and reach out when we see a strong potential fit.
