Job description

As a Software QA Engineer for the advanced semiconductor packaging equipment team at Kulicke and Soffa, you will play a key role in ensuring the quality and reliability of complex real-time software systems. These systems coordinate motion control, pick-and-place processes, image acquisition, and object recognition.

You will work in a collaborative Agile (Scrum) environment alongside developers, system engineers, and global teams to validate new features, identify defects, and improve overall product quality. This role includes both manual and automated testing, with exposure to simulation environments as well as physical equipment.

Main Responsibilities

• Develop, execute, and maintain test plans, test cases, and test scripts for real-time control systems
• Collaborate with cross-functional and multi-site teams to review and refine software requirements
• Perform functional, integration, system, and regression testing on semiconductor equipment software
• Identify, document, and track defects through resolution using standard defect management tools
• Design and implement automated tests using Python for system and integration-level validation
• Validate software in both simulation environments and on actual equipment
• Support equipment demos, qualification, and customer acceptance testing (buyoff)
• Investigate system behavior, troubleshoot issues, and work closely with developers to resolve defects
• Contribute to improvements in test coverage, QA processes, and tooling

Desired Skills and Experience

• ~4-8+ years of experience in software quality assurance and testing (flexible based on level)
• Strong understanding of software testing methodologies, test design, and defect lifecycle
• Experience with python test automation frameworks or scripting
• Exposure to C++ codebases for debugging, test design, or system understanding
• Experience testing real-time, embedded, or hardware-integrated systems
• Demonstrated systems thinking ability to understand end-to-end workflows, component interactions, and failure scenarios across software and hardware layers
• Exposure to Agile/Scrum development practices
• Experience with defect tracking/test management tools (e.g., Jira)
• Strong analytical, troubleshooting, and communication skills
• Ability to quickly understand complex system behavior and existing software functionality

Required Education

• Bachelor in Computer Science, Computer Engineering, Software Engineering or related fields.
