DWYER INSTRUMENTS, LLC • Simi Valley, California, United States • 1w ago

Description:
• Altium CAD design

• Design, develop, and maintain low-power sensor modules for healthcare, regulatory and industrial monitoring applications.

• Implement embedded firmware on microcontrollers (e.g., STM32, Nordic nRF, Ambiq Apollo) using C, Zephyr RTOS, and other frameworks.

• Develop and optimize wireless communication protocols including BLE, LoRa, Wi-Fi, and cellular (LTE-M, NB-IoT).

• Perform power optimization for battery-operated devices, including hardware circuit design, firmware strategies, and energy harvesting techniques for ultra-low-power designs.

• Design multilayer printed circuit boards (6+ layers) with emphasis on signal integrity, EMC/EMI mitigation, and optimized power section management.

• Integrate environmental sensors (temperature, humidity, differential pressure, gas) and ensure accurate data acquisition.

• Conduct debugging, validation, and testing of hardware/software systems, including data analysis and signal processing algorithms.

• Collaborate with cross-functional teams to design scalable cloud connectivity solutions using REST, MQTT, FastAPI, Azure/AWS.

• Provide technical documentation, support production, and ensure compliance with quality and safety standards, including ISO-26262 for V-model development processes and ISO-17025 for sensor calibration and testing.

Requirements:
• Bachelor's degree (or foreign equivalent) in Electrical Engineering, Computer Engineering, or related field.

• At least 5 years of progressive experience in embedded systems development.

• At least 3 years of experience in wireless sensor network projects.

• Experience with microcontrollers (STM32, Nordic nRF, Ambiq Apollo) and embedded C (barebone) programming.

• Experience with wireless communication protocols (BLE, LoRa, Wi-Fi, Cellular).

• Experience with RTOS (Zephyr, FreeRTOS) and low-power system design.

• Experience with sensor integration (temperature, humidity, pressure, gas).

• Experience with PCB design (6+ layers) and use of industry-standard EDA tools such as Altium Designer and KiCad.

• Experience with Linux system programming, kernel modules, and custom device driver development.

• Experience with cloud-based data integration (MQTT, REST APIs, Azure/AWS).

• Knowledge of signal processing, FFT analysis, and data compression methods is preferred.

Equal employment opportunity, including veterans and individuals with disabilities.
