Medical Software Engineer (Freelance)

• Freelance
• You will join as a 6-month Freelancer (Contractor), with a direct pathway to transition into a permanent full-time position as we scale
• As a Medical Software Engineer at DeepSpin, you will play a pivotal role in the implementation of the front-end and back-end of the MRI machine used by clinical and R&D users to leverage all the capabilities of the system
• You will take ownership of high-level interface descriptions — aligning them with internal and external stakeholders, refining them, and driving them through to implementation
• You will contribute to enhancing the performance and reliability of the system and will be responsible for testing and documentation needed for FDA 510(k) certification
• Develop and test software components for the DeepSpin MRI system
• Take ownership of high-level interface descriptions: elaborate, specify, and implement interfaces for internal and external stakeholders
• Critically review and challenge existing interface and system designs, identify weaknesses, and propose well-reasoned alternatives
• Ask the right questions early — surface ambiguities, unstated assumptions, and edge cases before they become costly problems
• Drive the translation from prototype to a deployed and cleared/certified product
• Champion software development best practices
