- 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

- 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)

- 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.
