SoC Firmware Engineer

Overview

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things solutions. We are building a low Earth orbit space system that will change how satellite and terrestrial IoT systems are designed, manufactured, and served. We need an Embedded Software Engineer to design, develop, and optimize low-level software with a strong emphasis on software/hardware co‑operation.

• Embedded Software Development:
  Plan, implement, and verify low-level software for embedded systems—including BSP, firmware drivers, and ROM code.
• RTOS Application and Driver Development:
  Develop device drivers for accelerators and heterogeneous multi‑processor applications, and provide system services for Zephyr, FreeRTOS, or similar.
• Software/Hardware Co‑design:
  Plan hardware accelerator usage models and software interfaces, including register definitions, task orchestration, and data flows.
• System Verification:
  Perform verification tasks related to firmware and hardware interactions—data‑flow profiling and hardware benchmarking.
• Embedded Security:
  Design and implement security mechanisms at the firmware level: secure boot, trusted execution environments (TEE), and control‑flow integrity.
• Hardware Simulation and Emulation:
  Verify software functionality and hardware interactions using simulation, hardware‑in‑the‑loop setups, and debugging tools.
• Continuous Integration and Test Frameworks:
  Develop and maintain test frameworks and vectors, integrate automated testing pipelines with CI/CD tools such as Jenkins, Git Lab CI, or Azure Dev Ops.
• Hardware Interaction & Documentation:
  Collaborate with hardware teams for seamless integration; prepare technical documentation and testing reports.

• Embedded C programming (experience in Rust a plus).
• Proficiency in scripting languages:
  Bash, awk, Python, Makefiles, and Tcl.
• Experience with ARM Corstone reference designs, ARM Cortex processors and associated tool chains.
• Understanding of low‑power design principles and power profiling.
• Debugging expertise with JTAG, GDB, and serial debuggers.
• Experience with CI/CD pipelines, Jenkins or Git Lab CI.
• Version control expertise with Git.

• Trusted Firmware‑M and MCUboot experience.
• PSA certification processes and requirements familiarity.
• Secure firmware updates (OTA) and boot loader development.
• AMBA interconnect protocols (AXI, AHB, APB).
• Hardware protocols: SPI, I2C, UART, GPIO.
• Hardware simulation tools and mock environments.
• Embedded security and cryptographic algorithms, including post‑quantum cryptography.
• 3
  
  GPP network protocols familiarity.
• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering or a related field.
