Senior QA Engineer – Embedded Software Quality

Daily tasks

• Test the embedded SDK on real devices: latency, memory, CPU/NPU/DSP load, power consumption, thermal behaviour and long-run stability.
• Audio or speech product testing.
• Design and maintain regression suites that catch performance and stability changes between releases.
• Build automated test tooling in Python and integrate it into CI.
• Profile on-device behaviour with adb, Perfetto and similar tools, and turn findings into clear, reproducible bug reports.
• Set up and run hardware-in-the-loop tests and device-farm executions.
• Work closely with SDK developers to investigate issues down to C/C++ level.

Requirements

• Several years of experience in QA / test engineering for embedded or mobile software.
• Strong Python for test automation and tooling.
• Hands-on experience with adb, Perfetto (or systrace) and on-device profiling.
• Ability to read and debug C/C++ code.
• Experience measuring latency, memory, CPU usage, power and thermal behaviour on real hardware.
• Experience with CI pipelines and automated regression testing.
• Fluent English
• Hardware-in-the-loop setups and device farms.
• Experience with NPU/DSP workloads or ML inference on edge devices.
