Principal Electrical Design Engineer

RxFunction•Eden Prairie, MN

About The Position

The Principal Electrical Design Engineer is a subject matter expert within the product development team, bringing deep technical expertise in mixed-signal electrical design. This role drives innovation by applying current best practices and emerging technologies to develop cutting-edge solutions and differentiated intellectual property. This is a high-impact, hands-on technical leadership role at the core of our product innovation. You will help define the next generation of our medical devices while strengthening the technical foundation needed to support a growing product portfolio. You will play a critical role in bridging early-stage innovation with scalable, reliable product development, directly influencing system architecture, product performance, and engineering processes as the organization grows. You thrive in a dynamic, fast-paced environment, balancing multiple priorities while independently driving complex projects from concept through production. You play a key role in defining system and hardware requirements, balancing speed with the rigor required for regulated medical devices.

Responsibilities

Drive key architectural decisions that impact current and future product platforms
Lead mixed-signal electrical design efforts across the full product lifecycle, from concept and development through launch and sustaining support
Translate user needs, clinical insights, and product requirements into robust system-level design solutions
Apply engineering analysis (analytical, simulation, and empirical testing) to ensure designs meet functional and reliability requirements
Define and implement system architecture and hardware design best practices
Evaluate and integrate new technologies (ICs, electromechanical systems, power circuits) with consideration for scalability, manufacturability, and supply chain constraints
Architect and develop automated test systems to support product validation, manufacturing, and continuous improvement
Lead products through regulatory compliance and testing (e.g., EMC, electrical safety), including standards such as FCC Part 15 and IEC 60601-1
Develop and maintain design control documentation (user needs, design inputs, verification/validation, DHF artifacts)
Mentor engineers and elevate technical standards across the team
Collaborate cross-functionally (mechanical, firmware, software, quality, and manufacturing) to translate product vision into robust, manufacturable solutions
