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 industry-leading ultrasound products from concept to commercial launch and production scale-up, leading electrical architecture and design, and collaborating with cross-functional teams.

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
