In this role you will help design, develop, test, and integrate the embedded flight software for Firefly spacecraft. You will work in a group of software engineers through all stages of spacecraft software development processes and collaborate with other engineering teams.
RESPONSIBILITIES
Design, develop, and test embedded firmware for microcontrollers and microprocessors in bare-metal or RTOS environments.
Architect and implement low-level drivers, communication protocols (I2C, SPI, UART, CAN, etc.), and system-level firmware for real-time applications.
Collaborate with hardware engineers to define system architecture, debug hardware/firmware interactions, and ensure seamless integration.
Optimize firmware for power efficiency, performance, and memory constraints in resource-limited embedded systems.
Participate in code reviews, maintain high-quality code standards, and document firmware designs and processes.
Contribute to system-level debugging, performance profiling, and validation of embedded systems.
Optionally, support FPGA integration, including firmware interfacing with FPGA designs, or contribute to custom OS builds using tools like Yocto or Buildroot.

Proven track record of delivering real-world industry projects involving embedded firmware developed as bare-metal or RTOS applications (e.g., FreeRTOS, Zephyr, or similar).
Strong programming skills in C/C++ for embedded systems, with experience in assembly language as a plus.
Experience with communication protocols (I2C, SPI, UART, CAN, USB, Ethernet, etc.) and real-time system constraints.
Familiarity with debugging tools (JTAG, SWD, oscilloscopes, logic analyzers) and embedded development environments.
Desired
Experience developing C++ applications for embedded systems.
Proficiency in CI/CD workflow development for embedded firmware projects (e.g., Teamcity, GitLab CI, or similar).
Experience with FPGA development, including firmware integration with FPGA designs.
Familiarity with custom OS builds using Yocto, Buildroot, or similar embedded Linux build systems.
