Software Engineer in Test, Core Technology (12-month contract)

What You'll Do 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 What You Bring 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 Preferred Experience with AOSP build systems (Soong/Make), Android Test Harness, or Vendor Test Suite (VTS)/Compatibility Test Suite (CTS) Experience with hardware-in-the-loop (HIL) test rig design and automation Familiarity with embedded Linux, Android kernel internals, and Treble/HAL architecture Knowledge of communication protocols (I2C, SPI, UART, BLE) used in sensor and firmware integration Experience with reliability metrics and frameworks (MTBF, FMEA, fault injection testing) Familiarity with motion sensing, IMUs, computer vision, or signal processing validation Experience working in small, high-performance technical teams Background in consumer electronics, robotics, or Android-based hardware products Passion for pushing reliability standards and deep root-cause problem-solving We Offer Competitive compensation package.
