Embedded Firmware Engineer

Pay: 60,000.00-65,000.00 per year

Job description:

Primary Objective

The Embedded Firmware Engineer is responsible for designing, developing, and testing firmware for advanced embedded systems used in high-power conversion and control applications. This role involves working with microcontrollers and SoCs (STM32H747, Texas Instruments J721E), implementing real-time operating systems (RTOS), and developing communication protocols (TCP/IP, Modbus, SPI, I2C, RS485, CAN).

The engineer will integrate control engineering techniques such as PID controllers, collaborate on system-level software in Python, and contribute to simulation and testing using Typhoon HIL. A strong understanding of electronics, power systems (e.g., inverters, battery management), and safe practices in high-power environments is essential. The role also includes developing PC-based test tools and participating actively in team meetings and agile workflows.

Key Responsibilities

The key responsibilities of this role include but are not limited to the following tasks:

• Firmware Development
• Develop embedded firmware in C and C++.
• Work with bare-metal and RTOS environments (MBED RTOS, FreeRTOS).
• Target platforms include STM32H747 microcontroller and Texas Instruments J721E SoC.
• System Integration
• Implement communication interfaces and protocols: Ethernet (TCP/IP, Modbus TCP), SPI, I2C, RS485 (Modbus RTU), CAN bus.
• Integrate control engineering techniques such as PID controllers for power control.
• Hardware Interaction
• Apply electronics knowledge and use test equipment to support embedded development.
• Work safely in high-power test environments (on-site and off-site).
• Power Systems
• Understand and work with grid-connected high-power conversion systems (e.g., inverters, battery management systems).
• Software Development
• Develop PC-based test tools using C# and Python.
• Contribute to system-level software development in Python.
• Simulation & Testing
• Use Typhoon HIL for model-based development and Hardware-in-the-Loop testing.
• Documentation & Collaboration
• Document code and development processes.
• Participate in team meetings and daily stand-ups, contributing technical insights.
