Staff Python Software Engineer, Butterfly Network

• Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience
• Extensive professional experience with Python in production environments
• Proven experience designing and owning SDKs, platforms, or shared libraries used by multiple teams or external users
• Demonstrated ability to quickly learn complex systems involving hardware, firmware, or imaging pipelines
• Experience interfacing Python with C/C++ or low-level device APIs
• Familiarity with automatic cross-language wrapper generation (Djinni, SWIG)
• Strong architectural and system design skills with an emphasis on clean, intuitive APIs
• Ability to work independently, prioritize effectively, and drive work forward with minimal direction
• Experience with concurrency models in Python (threading, multiprocessing, async)
• Low level resource management and multithreading execution (GIL, DMA, serial, USB, etc.)
• Strong testing discipline, including unit, integration, and hardware-in-the-loop testing strategies
• Excellent written and verbal communication skills, especially for technical documentation and cross-team alignment

Desirable

• 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
• 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
