Embedded Firmware Engineer at CALCULEX, Inc

We are seeking a skilled Embedded Software/Firmware Engineer to design, develop, and optimize firmware and low-level software for our embedded systems. The ideal candidate will have experience working with hardware interfaces, writing efficient, reliable code in C/C++, and a strong understanding of computer architecture and hardware-level programming. This role will also involve developing and maintaining the Board Support Package (BSP) for new hardware platforms, including bootloaders, peripheral drivers, and low-level system initialization.

• Design, develop, and maintain firmware for embedded systems, microcontrollers, and Linux applications.
• Develop and maintain BSPs
  for custom hardware, including initialization routines, device tree configurations, and hardware abstraction layers.
• Write and optimize low-level code
  in C/C++ for performance, reliability, and scalability on resource-constrained environments.
• Interface with hardware
  through device drivers and manage communications with peripherals (I2C, SPI, UART, etc.).
• Collaborate with hardware engineers
  to understand hardware specifications, timing constraints, and ensure firmware compatibility.
• Debug and troubleshoot firmware
  and BSP issues at the hardware level, using oscilloscopes, logic analyzers, and other debugging tools.
• Develop and execute tests
  to validate BSP and firmware functionality, reliability, and performance in real-time embedded systems.
• Maintain technical documentation
  for BSP, firmware design, implementation, and debugging processes.
• Perform code reviews
  and contribute to firmware architecture and process improvements.

• Bachelor’s degree
  in Computer Science, Electrical Engineering, or related field
• 2+ years
  of experience in low-level software/firmware development for embedded systems.
• Proficiency in C/C++programming with experience in low-level debugging and optimization.
• Experience with BSP development
  for embedded hardware, including system initialization and device tree configuration.
• Hands-on experience with hardware debugging tools
  such as oscilloscopes, multimeters, and logic analyzers.
• Familiarity with version control systems like Git
  .
• Experience with communication protocols such as I2C, SPI, UART, CAN, and USB.
• Knowledge of assembly language, ARM or similar microcontroller architecture is a plus.
• Strong problem-solving skills
  and the ability to work independently as well as in a collaborative team environment.
• Familiarity with scripting languages (e.g., Python) for test automation.
