Role: Embedded Systems Engineer

Dear Hiring Manager,

I am writing to express my interest in the Embedded Systems Engineer position, as advertised. With over 20 years of experience in embedded systems and a strong background in developing remote terminal units (RTUs) for electrical substations, I am excited about the opportunity to contribute to your team.

During last 2 years in Embedded Systems Inc. I have participated in development of devices built on GD32 MCU (stm32 equivalent) like ventilators and incubator temperature sensing monitors. And I was using I2C/UART/SPI/ADC protocols In C language.

I have also implemented bootloaders for different devices built on GD32 MCUs and on PIC MCUs.

In C++ and in C# I have written a serial terminal on desktop side for loading of HEX files into MCUs.

In G&W Canada I wrote different protocols for RTUs (DNP, Modbus, IEC101 to name a few). Leveraging my skills in HTML, CSS, JavaScript, and C language, I designed intuitive user interfaces that provided insights into voltage, current, power, and other critical parameters.

I am particularly drawn to this opportunity because of your commitment to innovation and excellence in the field of embedded systems. I am confident that my extensive experience and dedication to delivering high-quality solutions align well with the goals of your organization.

Thank you for considering my application. I am eager to further discuss how my skills and expertise can contribute to the continued success of your company. Please feel free to contact me at your earliest convenience to schedule an interview.

Warm regards,

Alexandre Arandorenko
