The **Arizona Center for Telemedicine and Digital Health** invites applications for a **Post‑Doctoral Fellow in Biomedical Internet of Things (IoT) and AI** to design and develop IoT interfaces for biomedical sensors and embedded microcontrollers used with vital‑sign monitors. This is a hands‑on research and development role combining embedded firmware, sensor electronics, secure data pipelines, digital signal processing, AI, and clinical validation to accelerate next‑generation remote monitoring solutions. **Key Responsibilities** - **Design and implement embedded firmware** for microcontrollers (ARM Cortex‑M, ESP32, etc.) to acquire, preprocess, and transmit physiological signals. - **Integrate biomedical sensors** (ECG, PPG, SpO₂, temperature, respiration, accelerometers) with analog front ends and ADCs. - **Develop low‑power IoT interfaces** using BLE, Wi‑Fi, LoRa, and MQTT/HTTP for reliable, secure data transfer to cloud and edge systems. - **Prototype hardware and electronics** including sensor interfacing, signal conditioning, and basic PCB bring‑up. - **Build end‑to‑end data pipelines**: embedded → gateway → cloud; implement data serialization, buffering, and fault tolerance. - **Validate performance** through bench testing and clinical pilot studies with vital‑sign monitors; collaborate with clinicians and clinical engineers. - **Ensure security and compliance**: implement encryption, authentication, and HIPAA‑aware data handling practices. - **Document and disseminate** results via technical reports, peer‑reviewed publications, and presentations. - **Mentor students and collaborate** across multidisciplinary teams (clinicians, software engineers, regulatory specialists). **Required Qualifications** - **PhD in Electrical Engineering, Computer Engineering, Biomedical Engineering, or related field** completed within the last 5 years. - **Strong embedded systems experience**: C/C++, RTOS, device drivers, low‑level peripheral control (ADC, DMA, I2C, SPI, UART).
