Embedded Validation & Test Engineer(Sensors, Android HAL)

Job Description

Sensors Key Responsibilities Perform validation and characterization of sensor subsystem components: Accelerometer Gyroscope Magnetometer Barometer Proximity / Light Sensor fusion (6-axis / 9-axis) Context detection (pedometer, activity recognition) Always-On DSP (SLPI/QDSP6) Validate the complete sensor pipeline across: Linux/Android sensor framework Sensors HAL CHRE DSP firmware SMD/SMGR interactions Execute tests for: Calibration accuracy Drift, noise and bias Responsiveness, sampling rate stability Latency/jitter Power/thermal behavior Concurrency and stress Debug and analyze issues using: logcat, bugreport QXDM/QDSS Sensors Diag tools perfetto/systrace Work with HW/FW teams to provide actionable root-cause analysis for sensor data issues. Validate Android sensor APIs , HAL behaviors, and custom OEM use cases. Use automation tools (Python, adb, sensor-test frameworks) for regression and continuous validation. Support sensor validation during BSP bring-up, OEM integration, and feature commercialization . Required Skills Strong understanding of: Sensor fundamentals (noise, drift, bias, sensitivity) Sensor fusion algorithms (Kalman filter, quaternion, AHRS) Android sensor framework & HAL architecture DSP-side sensor processing (SLPI/QDSP6) Experience with: Sensor logging/debug tools Characterization methods Automated test execution (Python) ADB/Android internals Ability to analyze complex system interactions (Sensors + Location + Camera + Display). Good to Have Experience with CHRE (Context Hub Runtime Environment) . Knowledge of low-power architectures and Always-On sensing. Familiarity with Machine Learning-based activity recognition . Exposure to: Location fusion (GNSS + sensors) AR/VR use cases Navigation-grade sensor accuracy OEM product launch or SoC bring-up experience. Education & Experience B.E/B.Tech/M.Tech (ECE, CS, EE). 2?7 years of experience in sensors testing, embedded validation, or Android HAL testing.
