Note: The job is a remote job and is open to candidates in USA. Noctrix Health is redefining the treatment of chronic neurological disorders with clinically validated therapeutic wearables. They are seeking an experienced and innovative Principal Electrical Engineer to lead the architecture, design, and development of electrical systems for next-generation therapeutic wearable devices.

Responsibilities

• 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

Skills

• 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
• 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
• M.S. in Electrical Engineering or a related technical field
• Experience developing wearable medical devices or compact battery-powered consumer electronics
• Experience designing low-power embedded systems for continuous or wearable operation
• Experience working within medical device quality systems and regulated product development processes (e.g., FDA design controls, ISO 13485)
• Demonstrated success leading complex h
