• Experience with Linux OS testing and embedded Linux environments.
• Good understanding of communication protocols and ability to validate protocol implementation.
• Hands-on experience with RS485 interface tools and communication/network sniffing tools.
• Exposure to test automation using Python.
• Experience with automation/testing frameworks such as Selenium or Playwright is preferred.
• Experience testing physical access controllers, access control devices, and readers is highly desirable.
• Strong analytical, troubleshooting, and debugging skills.
• Good verbal and written communication skills.

Key Responsibilities

• Perform manual and functional testing of physical access controllers and readers.
• Set up and configure test environments involving physical access controllers, readers, and embedded devices.
• Execute detailed test plans, test cases, test scripts, and test scenarios.
• Validate communication between devices using UART, RS485, SPI, and related interfaces.
• Validate implementation of communication protocols and identify protocol-level issues.
• Use RS485 interface tools, protocol analyzers, sniffing tools, and debugging utilities for troubleshooting.
• Identify, document, track, and verify defects using appropriate defect-tracking tools.
• Develop and maintain automated test scripts, preferably using Python.
• Execute regression, stress, load, performance, integration, and system testing.
• Analyze test results and provide detailed test reports and defect documentation.
• Collaborate with firmware developers, hardware engineers, and other QA teams to troubleshoot and resolve issues.
• Participate in test planning, test case reviews, and continuous improvement of testing processes.
• Ensure firmware releases meet defined quality, reliability, performance, and functional requirements.
