Desirable

• As an experienced Device Software Engineer at Butterfly, you will work at the intersection of cutting-edge ASIC hardware and the software that brings it to life — designing and developing the bare-metal firmware, device drivers, and embedded platform that powers our ultrasound imaging product line
• From early-stage SoC bring-up and pre-silicon emulation through to production-ready imaging pipelines, you will own critical work across the full hardware-software stack
• You will partner directly with our ASIC hardware and architecture teams to co-design software-hardware interfaces, develop hardware imaging pipelines, and build the Python tooling that drives ASIC configuration and validates system reliability
• We are seeking a talented, driven, hands-on problem-solver who is equally comfortable with a logic analyzer and a CI pipeline
• The ideal candidate is passionate about building rock-solid, low-level software that unlocks the performance of real-time imaging systems — and is excited to be a technical leader that the team and broader organization turns to for guidance
• Partner with our hardware, imaging, and mobile software teams to define and develop our next-generation embedded software architecture
• Design performant imaging sequencing control software, safety monitoring systems, and real-time data processing pipelines
• Design, develop, and test bare-metal firmware and low-level device drivers in C/C++ for custom ASICs based on RISC-V or similar processor architectures
• Lead early-stage SoC bring-up, debugging, and validation using both pre-silicon emulation environments and post-silicon hardware platforms
• Collaborate closely with ASIC hardware and architecture teams to define software-hardware interfaces and co-design critical system features
• Develop and maintain hardware imaging pipelines and interfaces (e.g., Cypress FX3 or similar platforms) to support the ongoing evolution of the Apollo ultrasound system
• Develop robust Python tools and scripts to drive ASIC configuration, validate hardware/firmware reliability, and execute ultrasound imaging sequences using both physical and mock (modeled) hardware
• Support hardware bringup by utilizing modern debugging techniques and tools
• Create automated, end-to-end tests and integrate them reliably into our hardware-in-the-loop CI pipeline
• Act as a thought leader to drive new technology, architectures, process, and infrastructure, and act as a mentor for fellow team members
• Perform a broad variety of tasks in support of the role and responsibilities
