Firmware Test Engineer

Role Overview

We are looking for a Firmware Test Engineer with 2-3 years of hands-on experience in firmware or embedded systems, who is passionate about understanding how devices behave in the real world. This role is ideal for engineers who enjoy working with real hardware, running systems in long loops, and investigating failures to understand not just what broke, but why.

You will work closely with firmware engineers to test device functionality, identify regressions, and improve system reliability. Over time, you will grow into building test automation, hardware-in-the-loop (HIL) setups, and firmware CI/CD pipelines.

If you are a firmware engineer—or come from a related embedded background—and are curious, motivated, and eager to expand your skill set into testing, automation, and reliability engineering, you are welcome to apply.

Why This Role Exists

 

As our devices and firmware scale, informal or manual testing is no longer sufficient. Devices must behave correctly not only in ideal conditions, but also across resets, power cycles, degraded communication, and long-running field scenarios.

 

This role exists to ensure that firmware failures are found early, in the lab—not in the field. By investing in firmware test engineering, we aim to improve observability, reduce deployment risk, and increase confidence in every firmware release.

 

 

 

• Understanding of black-box and white-box testing for firmware

• Ability to design tests based on:

  • External behavior and interfaces (black-box)

  • Firmware internals, state transitions, and logs (white-box)

  • Familiarity with structured and unstructured logging

  • Exposure to RTOS-based systems (Zephyr, FreeRTOS, or similar)

  • Familiarity with firmware upgrade or OTA/DFU workflows

  • Experience with or interest in hardware-in-the-loop (HIL) testing

  • Exposure to CI/CD pipelines for embedded or firmware projects

  • Experience running long-duration, loop-based, or stress tests

• 2-3 years of experience in firmware, embedded systems, or a related field

• Basic understanding of embedded systems and firmware behavior

• Ability to work hands-on with hardware systems

• Programming experience in Python (for tests and tooling)

• Basic familiarity with C or C++ to understand firmware behavior and logs

• Experience working with UART/USB/BLE or similar device interfaces

• Experience working in a Linux development environment

• Ability to analyze logs and identify abnormal or unexpected behavior

• Basic knowledge of Git or version control systems

• Strong curiosity and a willingness to learn
