Principal Engineer, Electrical Engineer

Butterfly Network, Inc. is driving a digital revolution in ultrasound imaging and sensing with its proprietary technology. The Principal Electrical Engineer is responsible for developing ultrasound products from concept to commercial launch, leading electrical architecture, collaborating with cross-functional teams, and ensuring compliance with medical device standards.

Responsibilities:

• Lead electrical architecture and design for medical devices across the full product lifecycle, from early feasibility and risk analysis through design transfer, manufacturing, and post-market support
• Investigate and resolve complex technical issues arising during development, verification, manufacturing, and field use
• Collaborate closely with mechanical, firmware, software, systems, quality, regulatory, manufacturing, and clinical teams
• Serve as the technical authority for critical design decisions, trade studies, and risk management activities
• Evaluate and introduce new technologies, components, and design methodologies to improve safety, reliability, and manufacturability
• Partner with contractors and external partners on development of novel medical and non-medical ultrasound based systems to be used in a variety of settings and industries
• Define and maintain electrical engineering standards, best practices, and design controls aligned with medical device quality systems
• Drive system-level requirements decomposition and ensure traceability between user needs, design inputs, and electrical design outputs
• Author, review, and approve schematics, PCB layouts, analyses, and verification/validation plans
• Ensure electrical designs comply with applicable medical device standards and regulations, including IEC 60601, ISO 14971, IEC 62304 (as applicable), FDA 21 CFR Part 820, and MDR/IVDR where relevant
• Lead and support electrical risk management activities, including hazard analysis, FMEA, and fault tree analysis
• Support supplier selection, component qualification, and technical audits for critical electrical components and subsystems
• Mentor and coach engineers on technical execution, design controls, and regulatory expectations

Requirements:

• A minimum of a BS in Electrical Engineering or related technical disciplines, Master or Ph.D. degree preferred
• 10+ years of electrical system design / development for medical devices
• Expert-level knowledge of analog and digital circuit design, power management, and system integration for medical devices
• In-depth knowledge of and experience with medical device development across the entire product development lifecycle from concept to commercialization, Class II/III medical device experience under IEC 60601
• Extensive experience with schematic capture, PCB design and review, and design for manufacturability (DFM) and test (DFT)
• Strong understanding of electrical safety, EMC/EMI, signal integrity, power integrity, and reliability in medical environments
• Demonstrated experience working within design control and quality management systems
• Proven ability to provide technical leadership without direct authority and influence cross-functional teams
• Excellent written and verbal communication skills, including technical documentation for regulatory submissions
• Experience working with global or cross-cultural engineering teams
