• Serve as the technical owner of the embedded software and firmware architecture for Zepto's GMR diagnostic platform.
• Design, develop, test, and maintain embedded firmware supporting instrument operation and control.
• Develop low-level device drivers and hardware abstraction layers (HAL) for sensors, processors, peripherals, and communication interfaces.
• Design firmware architecture that is scalable, maintainable, and compliant with medical device software development practices.
• Define and implement instrument workflows, operational sequences, state machines, and timing logic.
• Develop firmware supporting system startup, initialization, calibration, diagnostics, assay execution, error handling, and shutdown.
• Design and optimize data acquisition, data buffering, data validation, and communication between embedded firmware and application software.
• Collaborate with software engineering teams to define APIs, communication protocols, command structures, and software interfaces.
• Collaborate closely with the Senior Electrical Systems Engineer during hardware bring-up, board validation, and system integration.
• Implement firmware supporting GMR sensor data acquisition and signal processing algorithms.
• Troubleshoot embedded software, firmware, and hardware integration issues using oscilloscopes, logic analyzers, debuggers, and other engineering tools.
• Perform root cause analysis and implement corrective actions for software and system-level issues.
• Develop and execute unit testing, integration testing, system testing, and software verification activities.
• Develop and maintain software design documentation, architecture documents, software requirements, verification protocols, and technical records.
• Support software risk management activities including Software FMEA, hazard analysis, and cybersecurity risk assessments where applicable.
• Support FDA submissions by preparing software documentation required for Design Controls, Design History Files (DHF), and software lifecycle documentation.
• Collaborate with Quality Assurance and Regulatory Affairs to ensure compliance with FDA Quality Management System Regulation and other applicable standards.
• Participate in design reviews and provide technical leadership for embedded software architecture and best practices.
• Perform other duties and special projects as assigned.
