Experience

1. Embedded Firmware Test Engineer

   Abbott

   Jan 2025 — Present · Alameda, CA, US

   Specialized in comprehensive system testing for safety-critical handheld medical devices. Leveraged deep understanding of C and C++ embedded software design (Non-RTOS and RTOS) to develop and execute rigorous software integration test plans and protocols. Performed detailed requirement analysis, identified critical test scenarios, and managed hardware equipment selection. Conducted software code regression analysis and actively participated in design and code reviews, ensuring adherence to medical device software development processes.• Developed and executed test cases using Simulink Test and Simulink Real-Time to validate MATLAB/Simulink/Stateflow-based control algorithms for embedded medical devices, ensuring compliance with real-time constraints and FDA/IEC 62304 standards.• Performed Model-in-the-Loop (MIL) and Software-in-the-Loop (SIL) testing to verify algorithm correctness before hardware deployment, reducing defects in production.• Applied hardware-in-the-loop (HIL) testing to validate control loops, sensor feedback, and system state transitions in multi-therapy medical devices (e.g, PrisMax CRRT system, glucose monitors).• Utilized MATLAB scripting to automate test execution, data logging, and results visualization, improving testing efficiency by 30–40%.• Conducted ad hoc testing on real-time embedded systems (e.g, Green Hills Integrity OS) to evaluate concurrency, interrupt handling, and memory usage, uncovering timing-related defects.• Glucose Monitor Patch & Reader Testing• Developed and executed test protocols for a wireless glucose monitor patch & reader, validating real-time sensor accuracy, calibration algorithms, and hypo/hyperglycemia detection per FDA/ISO 13485 standards.
