Position Introduction/Key Duties
Cimarron is seeking a
Firmware Engineer to support our partnership with a commercial aerospace company at their rocket production facility in Briggs, TX. 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.
Key Duties:- 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.
Required/Desired Skills, Experience, and Education
Required Skills, Experience, and Education:- Due to facility security requirements, only U.S. citizens or permanent residents are eligible for consideration at this time.
- 5 or more years of professional experience in embedded firmware development in Linux environments.
- 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.
- Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
Desired Skills, Experience, and Education:- 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.
Resumes should list employment dates in month/year format (e.g., January 2020 - March 2024) for each position to meet customer and contract documentation requirements.
