Key Responsibilities

1. Functionality Testing

• Verify that all existing features perform as expected after each software update.
• Conduct testing across

  LEDs, LCD, MQTT, boot-up/shutdown times, facial recognition, VWD, ticketing

  , and other core functionalities.
• Perform

  hands-on testing

  directly at the cell, including multiple

  test walks

  to validate system behavior and feature stability.

2. New Feature Validation

• Identify new features introduced in each software release.
• Design and execute

  test cases

  specific to these features.
• Example: For VWD, test LED behavior, toggle functionality on the LCD, and remote enable/disable operations via MQTT.
• Conduct

  physical walk-through tests

  to ensure complete feature validation.

3. Lab Performance Testing

• Deploy new software versions to 50% of lab cells for a

  one-week observation period

  .
• Monitor

  AI (Torso)

  and

  Magnetometer (Ankle)

  detection performance.
• Compare data against baseline performance from previously approved versions.
• Identify anomalies such as

  error codes, crashes, or performance degradation

  .

4. Field Performance Testing

• Deploy and test new versions on a limited number of

  field cells (typically two at REH)

  .
• Evaluate

  real-world AI and Magnetometer performance

  and overall system stability.
• Report irregularities or deviations relative to prior versions.

5. Update Process Validation

• After successful validation, oversee the

  software update process

  across all remaining lab machines.
• Ensure updates complete successfully without interruptions or errors across multiple cells.

Primary Skills

• Functional and regression testing
• Test case design and execution
• Hardware and embedded system testing (LEDs, LCDs, sensors, etc.)
• Understanding of

  MQTT protocol

• Data monitoring and anomaly detection

Secondary Skills (Preferred)

• Experience with

  AI-based systems

  or

  sensor testing

• Familiarity with

  field testing

  and

  performance benchmarking

Preferred Industry / Domain

• Hardware-integrated software testing
• AI or IoT-driven environments.
