Staff Engineer, Butterfly Network

• 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 developing production-quality software in modern C++ (C++14/17/20)
• Proven experience designing and owning SDKs, platforms, or shared libraries used by multiple teams or external users, with a primary focus on Linux-based systems
• Comfort and familiarity working with Python
• Demonstrated ability to quickly learn complex systems involving hardware, firmware, or imaging pipelines
• 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
• Deep understanding of memory management, object lifetimes, and performance optimization in C++
• Experience with multithreading, concurrency, and synchronization in performance-sensitive systems
• 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 C++ Software Engineer to lead the design and development of a robust C++ 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
• As part of our team, your core responsibilities will include, but not limited to:
• Serve as the technical owner and architect for a C++ 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
