Lead Performance Engineer

Job Purpose At Emirates, we believe in connecting the world, to and through, our global hub in Dubai; and in constantly innovating to ensure our customers ‘Fly Better’. Emirates Group IT thrives on the dynamic nature of technology. Being pioneers in aviation innovation, we're always at the forefront, pushing boundaries. We're on the lookout for exceptional IT professionals to fortify our position as leaders in the industry. Embark on a journey with the world’s largest international airline and become a vital part of our cutting-edge information and technology team as Lead Performance Engineer. Working within the Quality Engineering QE team as a Lead Performance Engineer LPE is responsible for ensuring the performance availability scalability and reliability of a suite of products within an agile release train. Collaborating with multiple stakeholders to develop a fit for purpose performance engineering and testing strategy that covers all aspects of the product including cross program dependencies The LPE drives a performance driven culture and enables the development community to test earlier and test faster thereby enabling faster time to market and built-in quality In this role you will: - Design and execute complex test scenarios to ensure optimal functional/code coverage, and identify performance regressions or other anomalies. Establish performance baselines and identify key areas for improvements. - Participate in all phases of the Performance Engineering lifecycle for the products within an agile release train. - Review and critique the design and architecture of the solutions, and suggest options to improve performance and reliability. - Collaborate with architects and product owners to ensure NFR backlogs are maintained for the products, while also ensuring that each features and epics have NFRs defined - Work with IT and business stakeholders to design workload models. Conduct frequent reviews and updates of the workload models, thereby ensuring the effectiveness of the non-functional tests. - Collaborate in investigating and resolving performance and/or availability issues to reduce defect leakages to production. - Establish appropriate performance gates within the Continuous Integration or Continuous deployment pipelines. - Implement fit for purpose performance testing frameworks for the products. Enable the developers and testers to use these frameworks, thereby increasing the autonomy within feature teams. - Provide timely feedback to the Senior Principal Performance Engineer to enhance and maintain the performance testing frameworks, so as to improve efficiency and productivity. - Conduct thorough performance testing result analysis, through statistical analysis of data from multiple sources. Qualification To be considered for this role, you must meet the below requirements: - 8+ years of hands-on experience in Performance Engineering, including performance testing, profiling, and tuning of highly available and scalable mission-critical applications. - 3+ years of experience leading performance engineering practices for a suite of products, including web, mobile, and desktop applications. - Proven expertise in performance tuning and optimization of applications and systems, including identifying bottlenecks and enhancing overall efficiency. Proficient with application profiling tools like YourKit and JProfiler - Extensive experience with commercial and open-source load testing tools such as LoadRunner, Gatling, JMeter, etc., as well as client-side performance analysis tools like Sitespeed.io, WebPageTest, and Lighthouse. - Strong ability to review application architecture and design principles, with a focus on recommending improvements to enhance system performance. Advanced knowledge of software architecture concepts, including current technology trends and best practices. - Proficient in monitoring and observability solutions, with a solid understanding of APM, infrastructure monitoring, Open Telemetry, logging, and tracing. - Skilled in building realistic and data-driven workload models for performance testing by analyzing application logs, APM data, system metrics, and user behavior patterns. Proficient in deriving concurrency levels, transaction mix, and traffic distribution based on production telemetry and historical usage data. - Comfortable working across cloud platforms (AWS, Azure, GCP), on-premises, or hybrid environments, with demonstrated expertise in Kubernetes, containerization, and orchestration tools. - In-depth understanding of both relational and NoSQL databases, with the ability to diagnose and resolve database performance issues. - Familiar with DevOps practices and experienced in setting up performance gates within CI/CD pipelines. Preferred skills - Familiarity with resiliency testing and chaos engineering, including exposure to commercial or open-source tools used to assess system behavior under failure scenarios. - Experience with capacity planning an
