About the role

Key responsibilities & impact

help design, develop, test, and integrate the embedded flight software for Firefly spacecraft
work in a group of software engineers through all stages of spacecraft software development processes
collaborate with other engineering teams
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.

Requirements

What you’ll need

Bachelors or Masters degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field
3+ 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
