Day 1 on the Embedded Systems Engineer path.

What a Embedded Systems Engineer does

Builds and tests software that runs inside devices so products work safely, reliably, and on time.

  • Design firmware for microcontrollers and connected devices
  • Write and review C or C++ code for real-time behavior
  • Bring up new hardware by testing boards, sensors, and interfaces
  • Debug crashes and timing issues using logs and hardware tools
  • Integrate drivers, communication stacks, and device protocols
  • Optimize memory, power use, and performance on limited hardware
  • Document designs and support manufacturing and field issues

A day in the life

  1. Plan tasks with the team, then pick a bug or feature to ship
  2. Write code, run unit tests, and flash builds onto a device
  3. Use a debugger or logic analyzer to trace a hardware-software issue
  4. Review changes, update docs, and sync with hardware and QA teams

Tools you will use

Languages: C, C++, PythonVersion control: GitDebugging: GDB, JTAGBuild systems: Make, CMakeTest tools: Unit testing frameworksHardware tools: Oscilloscope, Logic analyzerRTOS: FreeRTOS, Zephyr
