Embedded Validation & Test Engineer(Sensors, Android HAL)

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).
• 27 years of experience in sensors testing, embedded validation, or Android HAL testing.
