Principal Electrical Engineer

Role Overview

• Serve as the technical authority for electrical architecture and hardware design across Noctrix’s therapeutic wearable platforms.
• Lead hands-on design and development of complex analog, digital, and mixed-signal circuits for medical device systems, including schematic capture, PCB layout oversight, and component selection.
• Architect robust electrical systems that meet the performance, reliability, and safety requirements of prescription medical devices operating in FDA-regulated environments.
• Drive full lifecycle hardware development—from early concept and feasibility through detailed design, verification, validation, and transfer to manufacturing.
• Perform and guide detailed electrical engineering analysis including signal integrity, power management design, noise mitigation, and system-level performance optimization.
• Lead rigorous troubleshooting and root cause investigations for electrical and system-level issues during development, verification testing, and manufacturing.
• Develop, review, and maintain high-quality design documentation in compliance with medical device quality systems, including design inputs/outputs, risk analysis, verification protocols, and traceability artifacts.
• Ensure electrical designs support regulatory compliance requirements including IEC 60601 safety, EMC, and applicable medical device standards.
• Work closely with firmware and systems teams to develop integrated hardware solutions that deliver reliable therapeutic performance and exceptional patient experience.
• Mentor engineers and contribute to raising the technical depth and engineering rigor of the hardware team.
• Support manufacturing partners and internal teams in design for manufacturability (DFM), testability (DFT), and scale-up to production.
• Contribute to the identification and development of new electrical technologies, architectures, and hardware platforms aligned with Noctrix’s long-term product roadmap

Requirements

• B.S. in Electrical Engineering or equivalent technical discipline (M.S. preferred)
• Minimum 15 years of experience designing and developing complex electrical systems, preferably in medical devices or other regulated industries (e.g., aerospace, automotive, industrial safety systems)
• Deep expertise in analog, digital, and mixed-signal circuit design, including schematic capture, PCB layout guidance, and component selection
• Strong proficiency with Altium Designer or similar professional PCB design tools
• Demonstrated experience architecting and delivering battery-powered embedded systems, including power management, DC-DC conversion, Li-ion battery management, and charging circuitry
• Experience designing systems using microcontrollers and embedded firmware interfaces, with working knowledge of C-based firmware development
• Strong understanding of common embedded communication protocols including USB, I²C, SPI, UART, and BLE
• Experience performing electrical analysis and simulation, including signal integrity, power integrity, and noise mitigation in compact electronic systems
• Experience designing for and supporting EMC/EMI compliance and testing, including familiarity with IEC 60601, EN 61326, or comparable standards
• Demonstrated experience delivering hardware–software integrated products from early concept through verification, validation, and commercialization
• Experience working within regulated development environments, including familiarity with FDA design controls, design history files (DHF), and traceable engineering documentation
• Exceptional hands-on engineering capability, with a proven ability to troubleshoot complex electrical and system-level issues
• Ability to produce clear, rigorous engineering documentation including design analysis, test reports, verification protocols, and design rationale
• Strong communication and collaboration skills across multidisciplinary teams including firmware, mechanical engineering, product management, clinical, and manufacturing teams
• Ability to communicate complex technical concepts clearly to both engineering peers and executive leadership.
