Firmware Engineer

abra R&D is seeking a Firmware Software Engineer!

In this position, you will design and develop embedded software components, work closely with hardware interfaces, and take ownership of features from concept to deployment.

You will be part of a highly skilled engineering team, contributing to system-level architecture, performance optimization, and robust real-time functionality.

Key Responsibilities:

• Validate a custom ARM-based MCU on a customer board post electrical bring-up, developing bare-metal C/C++ firmware to verify all subsystems (peripherals, memory, clocks, power, interrupts, DMA).
• Work closely with custom coprocessors, including non-standard assembly and specialized toolchains.
• Perform hardware-level debugging using oscilloscopes, logic analyzers, and JTAG/SWD, while analyzing datasheets and schematics.
• Automate validation flows with Python/Bash and document test results, defects, and coverage.
  
  

• B.Sc. in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• 5+ years of experience in embedded / firmware development.
• Strong programming skills in C, including low-level or real-time development.
• Experience bringing up or validating silicon, SoCs, or custom MCUs
• Ability to read and work from schematics and hardware documentation
• Solid understanding of ARM architecture (exception model, memory map, boot sequence, registers)
• Experience with cross-compilation toolchains and linker scripts
• Familiarity with lab equipment (oscilloscope, logic analyzer, JTAG/SWD probes)
  
  

• C++ in embedded context (low-level, no STL bloat)
• Python/Bash scripting for test automation
• Exposure to CI/CD or DevOps concepts applied to hardware validation
