About This Role

iRhythm is seeking a Senior Electrical Engineer with extensive experience in electrical testing, failure analysis, manufacturing support, and quality-driven problem solving within a regulated medical device environment. This role is responsible for leading complex investigations, developing and validating test methods, supporting manufacturing operations, and driving product quality and reliability improvements. The ideal candidate possesses strong expertise in PCBA troubleshooting, root cause analysis, test system development, process validation, and cross-functional collaboration within a Quality Management System (QMS).

Essential Duties And Responsibilities

• Lead electrical, functional, and failure analysis investigations across prototype, verification, validation, and production phases to ensure compliance with design, quality, and regulatory requirements.
• Perform root cause analysis and troubleshooting of PCBAs, electronic assemblies, and medical device systems related to manufacturing failures, reliability testing, nonconformances, customer complaints, and field returns.
• Develop, maintain, and improve electrical test methods, fixtures, automated test systems, and diagnostic processes to ensure accurate, repeatable, and traceable testing.
• Conduct board-level debugging and fault isolation using laboratory equipment including oscilloscopes, logic analyzers, digital multimeters, thermal imaging systems, and power analyzers.
• Identify electrical, component, manufacturing, and design-related failure mechanisms and drive effective corrective and preventive actions to improve product quality and reliability.
• Support disposition of nonconforming material through technical investigations and recommendations for rework, repair, containment, or scrap.
• Lead and support process validation (IQ/OQ/PQ) and test method validation activities for manufacturing and test systems.
• Participate in CAPA, nonconformance, complaint investigations, and risk assessments (FMEA) to identify root causes and implement corrective actions.
• Analyze manufacturing, reliability, and field performance data to identify trends, recurring failure modes, and opportunities for quality, yield, and reliability improvement.
• Collaborate with Manufacturing, Quality, Reliability, Supplier Quality, Operations, and Design Engineering teams to support product transfer, production readiness, and continuous improvement initiatives.
• Partner with suppliers, contract manufacturers, and external laboratories to support advanced failure analysis activities, including X-ray, cross-sectioning, microscopy, and material characterization.
• Develop and maintain SOPs, work instructions, and investigation procedures that support effective testing, troubleshooting, and manufacturing operations.
• Drive initiatives focused on test automation, process efficiency, defect reduction, yield improvement, and enhanced product reliability.
• Ensure compliance with FDA, ISO 13485, IEC 60601, and applicable Quality Management System requirements.
• Prepare clear, data-driven technical reports documenting investigation methods, findings, root cause conclusions, risk assessments, and corrective actions.
• Provide technical leadership and mentorship to engineers and technicians, promoting best practices in testing, troubleshooting, and failure analysis.
