We are seeking a highly skilled and hands-on Senior Performance Engineer to join our Performance and Site Reliability Engineering (SRE) team. Our team is responsible for ensuring the high performance, scalability, and reliability of our systems and applications, and we are looking for an experienced engineer to lead these initiatives. As part of a small, dynamic team of five—including two DevOps engineers, two performance testers, and a performance analyst—you will play a critical role in optimizing software performance and developing in-house tools.
The ideal candidate will have a strong background in performance testing and development, capable of designing and executing performance testing frameworks, scripting automated tests, and contributing to the enhancement of our custom tooling, ASIACQ (Configuration Excellence). Given the nature of the role, project management skills are highly desirable, as the position requires a high degree of autonomy and self-direction to manage multiple initiatives effectively.

Join the S&A Engineer QA subdepartment as a Senior Performance Engineer, and this is some of what you’ll be doing:

• Design, develop, and execute performance test scripts to identify performance bottlenecks and optimize system performance.
• Analyse test results and performance metrics to identify bottlenecks, areas for optimization, and opportunities for improvement.
• Bring visibility to performance metrics and understand their effects on customers.
• Collaborate with development, QA, and operations teams to implement performance enhancements and ensure the scalability and reliability of our applications.
• Leverage your development background (Java, Python, or similar) to contribute to team tooling and infrastructure.
• Communicate performance testing outcomes, system optimizations, and potential risks to both technical and non-technical stakeholders.
• Contribute to the continuous improvement of our testing and quality assurance processes, tools, and methodologies.
• Identify project risks, potential bottlenecks, and mitigation strategies to ensure performance goals are met.
