Role
Who you are
- 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
- 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
- Experience in medical devices, ultrasound systems, imaging platforms, or other regulated environments
- Familiarity with real-time systems, data streaming, or high-throughput image pipelines
- Experience defining SDK governance, versioning strategies, and long-term platform roadmaps
- Knowledge of relevant standards (e.g. , IEC 62304, ISO 13485, FDA software lifecycle expectations)
- Experience supporting external developers or partners using a published SDK
What the job involves
- 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
- 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
Our take
Ultrasound machines are invaluable tools for clinicians, but these setups remain inaccessible to many. This is due to existing machines relying on quartz-powered transducers and other specialized components, resulting in a very large size and an expensive price tag.
Butterfly Network builds innovative, inexpensive, and compact ultrasound technology in order to increase access to clinics across the U.S. The device is around the same size as an electric razor, a design made possible by storing the ultrasound technology on a chip as opposed to a semi-conductor.
Whilst the company has not innovated the ultrasound process itself, Butterfly Network has found a unique gap in the market by providing inexpensive and easy-to-use access to the many clinics that could benefit from having an ultrasound machine. The device is available for under $2,000, but software designed for easy access and interpretation of ultrasound imagery comes at an additional monthly cost.
The company has also launched its very own AI marketplace called ''Butterfly Garden'' where medical device companies, virtual care companies, and AI developers can access Butterfly's software development kit. This will enable them to build new applications that reach Butterfly's prominent installed base.
