Job summary

Nex is seeking a Software Engineer in Test to own stability and reliability testing for the Motion Development Kit, firmware, and hardware modules powering Nex Playground's motion-sensing device. You will build automated test frameworks, implement soak/stress testing, and create regression suites integrated into CI/CD.

You will collaborate with firmware, hardware, and framework teams to ensure testability across the Android stack, from sensor drivers to MDK APIs.

Qualifications

• 3+ years of professional experience in software test engineering, reliability engineering, or QA for embedded/firmware, Android, or hardware-integrated systems.
• Proficiency in Python, with experience in at least one systems language (C++, C#, Java, Rust, or Go)
• Hands-on experience with stability, stress, soak, or endurance testing methodologies.
• Experience testing Android/AOSP platforms, HAL, embedded firmware, device drivers, or hardware modules (sensors, motion tracking, cameras, or similar)
• Strong debugging skills across hardware, firmware, and software layers, including logcat, kernel logs, bug reports, logic analyzers, or serial/hardware diagnostics
• Experience building or maintaining CI/CD pipelines and automated regression suites

Responsibilities

• Design and build automated stability and reliability test frameworks for the Motion Development Kit (MDK), firmware, and hardware modules on an AOSP-based platform
• Develop soak testing, stress testing, and endurance testing pipelines to surface memory leaks, crashes, thermal issues, ANRs, and long-running failures
• Build test harnesses and hardware-in-the-loop (HIL) rigs to validate sensor, camera, and motion-tracking hardware under real and simulated conditions
• Create regression suites for firmware, HAL, and MDK releases, integrated into CI/CD to catch stability issues pre-release
• Investigate, reproduce, and drive root-cause analysis of field failures, crashes, kernel panics, and intermittent hardware/firmware defects using Android bug reports, logcat, and kernel logs
• Define and track reliability metrics such as MTBF, crash rates, ANR rates, and failure recurrence across hardware revisions and firmware/AOSP builds
• Partner with firmware, hardware, and platform engineers to define quality gates and exit criteria for new hardware/firmware/AOSP releases
• Write clean, well-tested test code and tooling that raises the engineering bar across the team
• Build dashboards and reporting for test coverage, defect trends, and release stability
• Participate in code reviews and contribute to shared tools, infrastructure, and cross-role projects (20% Time)
• Work with the dual-leadership model (Engineering Manager and Tech Lead) to align on quality priorities and technical direction
• Document test strategies, systems, and findings to support team knowledge sharing
