How to write an embedded software engineer resume

By , founder of ResumeForDev · Updated

Short answer

An embedded software engineer resume should show the devices you shipped firmware for and the constraints you worked within: memory, power, real-time deadlines, safety. Name the microcontroller family, the RTOS or embedded Linux, and the protocols (SPI, I2C, CAN) in each bullet, and quantify results like boot time, power draw, memory footprint and field defects. List C and C++ first, then hardware tools such as oscilloscopes and logic analyzers.

Key points

  • Name the hardware: MCU family, RTOS, bus protocols.
  • Constraint numbers are your metrics: RAM, flash, power, latency.
  • Mention shipped products and volumes where you can.
  • Safety standards (ISO 26262, IEC 62304) are strong keywords if you've worked under them.

What embedded hiring managers look for

Embedded roles care about whether you can make software work on real hardware under tight limits. Reviewers look for the platforms you know, your debugging skill at the hardware level, and evidence that your code shipped in a product. General software resume advice still applies (results, numbers, one page), but the vocabulary is different.

Before and after

Before:Developed firmware for embedded devices in C.

After:Wrote FreeRTOS firmware in C for an STM32-based sensor node (256KB flash), cutting average power draw 38% to extend battery life from 9 to 14 months across 50k shipped units.

Example embedded bullets

  • Brought up a custom ARM Cortex-M4 board, writing SPI, I2C and UART drivers and a bootloader with secure firmware updates over BLE.
  • Reduced boot time on an embedded Linux (Yocto) device from 28 to 9 seconds by trimming services and parallelising init.
  • Implemented CAN bus communication for an automotive ECU under ISO 26262 ASIL-B processes, with MISRA C compliance checked in CI.
  • Tracked down an intermittent watchdog reset using a logic analyzer and trace logs, fixing a race condition that caused 2% of field returns.
  • Built a hardware-in-the-loop test rig in Python that runs 300 firmware tests per commit on real boards.

Embedded systems skills

  • Languages: C, C++, Python (test and tooling), Rust (if used), assembly
  • Platforms: ARM Cortex-M, STM32, ESP32, Nordic nRF, embedded Linux (Yocto, Buildroot)
  • RTOS: FreeRTOS, Zephyr, ThreadX
  • Protocols: SPI, I2C, UART, CAN, BLE, Modbus
  • Tools: JTAG/SWD debuggers, oscilloscope, logic analyzer, GDB, Git, Jenkins

On ResumeForDev, set your target role to “Embedded Software Engineer”. Without a job post, the keyword check falls back to a general software vocabulary, so for this role it's worth pasting the job description. Paste a job description and the keyword check uses that post's terms instead; on Pro, the writer also tailors the bullets to it. Before writing, it asks follow-up questions about the numbers above, and it removes any number or skill you never gave it. Your first resume is free.

Frequently asked questions

What skills should an embedded software engineer list?
C and C++, the microcontroller families and RTOS you've used, bus protocols like SPI, I2C and CAN, embedded Linux if relevant, and hardware debugging tools.
How do I quantify embedded systems work?
Power draw, battery life, memory footprint, boot time, latency, units shipped, field defect rates and test coverage on hardware.
Should I include hardware projects on an embedded resume?
Yes, especially early in your career. Name the board, the peripherals you wrote drivers for and the problem you solved.
