As a Software Engineer in Test at Nex, you will own stability and reliability testing for the Motion Development Kit (MDK), firmware, and hardware modules that power Nex Playground's AOSP-based motion-sensing device. You will build automated test frameworks, stress/soak testing infrastructure, and validation tools that catch instability, regressions, and hardware-integration failures before they reach production. You will work closely with the Framework Engineering and firmware/hardware teams to embed testability across the full Android stack, from low-level sensor drivers and HAL layers up through the MDK APIs that game developers build on .
This role sits within a small, highly technical team that values both specialization and collaboration, with clear ownership of quality across core technology areas .
You are drawn to solving hard reliability problems in systems where hardware, firmware, and Android software all have to work together flawlessly, day after day. You care deeply about long-run stability, not just passing a test once, but proving a system holds up under sustained load, edge cases, and real-world conditions. You thrive in environments where deep systems debugging, Android/AOSP internals knowledge, and rigorous testing discipline directly shape what the platform can confidently ship .
