Hardware QA Engineer (manual)

Neybo is an AI companion device for kids. Unimatch Lab is an AI-agent-run venture builder with seven products across Future of Work, Longevity, Kids Universe, and Education.

• Run functional and regression tests on every new firmware build
• Test devices across hardware versions, from bare boards to units close to production samples
• Run full test cycles on vendor development boards as the application layer is integrated into a unified firmware image
• Benchmark CPU performance, thermal stability and throttling, memory use and throughput, and Wi-Fi stability across frequencies and channels
• Localize defects to hardware or firmware before handing them to the appropriate team
• Test hardware codec performance across application scenarios
• Test and validate speech interaction scenarios involving wake-word, voice quality enhancement algorithms, and speech recognition running alongside other applications
• Record test results in a structured, repeatable format
• Reflash boards and operate test equipment as part of the daily testing cycle
• Use hardware debug tools and protocols, including UART, ADB, SSH, Telnet, and TFTP
• Keep pace with the firmware team's release cadence and validate each new build quickly
• Analyze running Linux processes and identify the most CPU- and memory-intensive processes under different conditions

• 2–3+ Years of hands-on hardware QA or embedded device testing experience
• Experience testing physical boards and finished devices across build iterations
• Experience regression testing firmware on real hardware
• Working knowledge of CPU, thermal, memory, and Wi-Fi benchmarks
• Comfortable with regularly reflashing boards and working directly with hardware
• Experience with headless Linux interfaces, including terminal and tmux
• Familiarity with system benchmarking tools such as top, htop, and tinymembench
• Basic skills with measurement and diagnostic equipment, including multimeters, oscilloscopes, thermal cameras, and bench power supplies
• Experience using a serial console or JTAG to retrieve device logs and debug output
• English B2+, written and spoken
• Будет плюсом: experience writing structured defect reports with reproduction steps, environment, expected and actual results; basic electronics knowledge for localizing issues at the hardware/firmware boundary; experience testing voice-interface or similar consumer IoT devices

• Paid in USDT
• Full-time, remote B2B contract
• Remote work is possible with an equivalent hardware bench at the candidate's location; Moldova is preferred
