  • 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.

QUALIFICATIONS

Required
  • Bachelor's or Master's 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.
  • 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.

Firefly offers outstanding benefits for our employees, including generous health, dental and vision plans with low plan deductibles, parental leave, educational reimbursement, short term disability, and flexible PTO options.
