What are the responsibilities and job description for the Sensor Test Engineer position at Quest Global?
We are looking for a Sensor Test Engineer to join the hardware team. This role is responsible for end-to-end sensor validation, capacitive touch (captouch) modelling, and testing on next-generation wearable platforms. You will work closely with cross-functional teams—including manufacturing, firmware, systems integration, and product design engineering—to ensure sensor subsystems meet performance, reliability, and production-readiness requirements..
Key Responsibilities
Sensor Validation
- Develop and execute validation test plans for sensors integrated into wearable hardware (e.g., proximity, ambient light, IMU, captouch)
- Prototyping of new hardware/sensors.
- Characterize sensor performance across environmental conditions (temperature, humidity, mechanical stress)
- Analyze data sensor data to identify discrepancies and root-cause failures
- Define pass/fail criteria and contribute to sensor specifications
Captouch Modelling & Testing
- Build and maintain capacitive touch sensor models (FEM/analytical) to predict performance across design variations
- Conduct captouch sensitivity, linearity, and noise characterization
- Collaborate with firmware teams for sensor development
Manufacturing Interface
- Previous experience in a fast-paced hardware development environment (EVT/DVT/PVT cycles) - must have
- Partner with manufacturing and NPI (New Product Introduction) teams to define sensor test procedures for production lines
- Support manufacturing yield analysis and troubleshoot sensor-related production issues
- Develop and document sensor calibration procedures for factory deployment
- Communicate with manufacturing teams in China to troubleshoot sensor-related test fixture bring up.
Cross-Functional Collaboration
- Work with Product Design Engineers, Systems Integration Engineers, and Electrical Engineers
- Coordinate with firmware/software teams on sensor driver integration and tuning
- Provide sensor performance data and recommendations to support system-level trade-off decisions
- Contribute to design reviews and risk assessments
Required Qualifications
- B.S. or M.S. in Electrical Engineering, Mechanical Engineering, Physics, or related field
- 3 years of experience in sensor characterization, validation, or test development
- Experience with FEM simulation tools — COMSOL and/or Ansys (Mechanical & Electronics Desktop)
- Proficiency with lab equipment (oscilloscopes, LCR meters, environmental chambers, data acquisition systems)
- Experience with data analysis tools (Python, MATLAB, or similar)
- Strong understanding of sensor physics (capacitive, optical, inertial)
- Experience interfacing with manufacturing or NPI teams
Preferred Skill
- 5 yrs of experience.
- Experience in capacitance extraction and electrode simulation
- Familiarity with consumer electronics or wearable device development
- Experience with embedded systems and sensor firmware debugging
- Knowledge of touch controller ICs (CSD/CSX sensing methods) and their configuration/tuning
- Strong communication skills for cross-site and cross-functional collaboration
