We're a team of bold thinkers, problem-solvers, and innovators ready to shape the future of medical imaging. Let's build something extraordinary together! Job Description We are seeking a Staff Python Software Engineer to lead the design and development of a robust Python Software Development Kit (SDK) for controlling and interfacing with an ultrasound imaging device. This SDK will serve as a common platform used by internal development teams and external partners. This is a senior individual contributor role for an engineer who is a fast learner, self-starter, and capable of working autonomously in a complex, hardware-adjacent environment. The ideal candidate thrives in ambiguous problem spaces, takes full ownership of technical outcomes, and drives solutions from concept through production and external adoption. As part of our team, your core responsibilities will include, but not limited to: Serve as the technical owner and architect for a Python-based SDK controlling an ultrasound imaging device. Lead SDK design decisions with a focus on API clarity, usability, scalability, and long-term maintainability. Rapidly learn complex device behavior, imaging workflows, and system constraints to make informed design decisions. Work autonomously to define requirements, propose solutions, and execute with minimal supervision. Collaborate cross-functionally with firmware, hardware, imaging, systems, and product teams to define control and data interfaces. Design abstractions for device configuration, image acquisition, real-time data streaming, and system state management. Establish best practices for SDK architecture, testing strategy, documentation standards, and release processes. Ensure SDK robustness, performance, and reliability in hardware-integrated and real-time contexts. Drive SDK versioning, backward compatibility, deprecation policies, and partner-facing release strategy. Create and maintain high-quality developer documentation, examples, and reference implementations. Mentor and provide technical guidance to other engineers contributing to the SDK or adjacent platform components. Support internal teams and external partners with integration, debugging, and advanced use cases.
