Hardware-in-the-Loop Test Engineer - AI Device QA

Hark; San Jose, Northern (CA, KY); Hybrid; USD 150,000 - 350,000; Full time

Job summary

Hark is seeking a Software Test Engineer to design and build hardware-in-the-loop test benches for our device software. You will create test infrastructure in Python, design tests from product requirements, and convert results into actionable insights used by hardware, firmware, and software teams.

You'll automate end-to-end tests for radios, audio, cameras and sensors, integrate tests with CI/CD, and help ensure high-quality performance on real devices across wireless and multimedia workloads.

Qualifications

• 5+ years of experience testing software on hardware devices.
• Hands-on experience building HIL test benches for automated software testing on devices.
• Proficiency in Python for building test cases and test infrastructure with CI/CD.
• Experience designing test strategies and test cases from product requirements.
• Testing experience with Wi-Fi, LTE, 5G, Bluetooth, GPS/GNSS.
• Experience testing devices with multimedia inputs and outputs, such as audio and cameras.
• Ability to root-cause failures across hardware, firmware, and software, and communicate findings clearly.

Responsibilities

• Build physical test systems and HIL benches for software verification, starting from zero.
• Develop the test infrastructure and libraries, mostly in Python, that let any engineer run develop and run automated tests on hardware devices.
• Design test strategies from product requirements and build the test cases that produce the quality signals necessary for rapid deployment.
• Automate end-to-end tests that verify radios and sensors such as Wi-Fi, LTE, 5G, Bluetooth, GPS/GNSS, audio, camera and video input and output.
• Interpret test results, root-cause and document failures, and fix issues in the product when it makes sense.
• Integrate test runners with CI/CD so builds are tested automatically on real devices.
• Partner with device software, backend, audio, radio, and ML teams so their work can be tested on shared benches.
