GCP Architect (Airline Domain)

Job Description: Performance Engineering Architect Mainframe to GCP Cloud Transformation (Airlines Domain) Position Overview We are seeking an accomplished Performance Engineering Architect to lead the performance strategy for a large-scale Mainframe TPF and underlying tech stack, data files, services, business logic to Google Cloud Platform (GCP) transformation within the Airlines domain. The role demands a deep understanding of high-performance systems that require millisecond-level response accuracy, while collaborating with diverse teams to establish consistent frameworks, tools, and best practices that drive reliability and scalability across the transformation journey. Key Responsibilities 1. Performance Strategy & Architecture • Define the end-to-end performance engineering strategy for the Mainframe to GCP transformation initiative. • Ensure airline applications meet stringent response time SLAs in the millisecond range. • Architect scalable and high-performing cloud-native solutions capable of handling concurrent workloads typical in airline systems. 2. Collaboration & Leadership • Work collaboratively with more than 90 agile teams, including architects, tech leads, product owners, and performance engineers. • Act as the primary advisor for integrating performance best practices into the agile delivery lifecycle. • Conduct regular sprint-level reviews to ensure that performance benchmarks are consistently achieved. 3. Tools & Frameworks • Design, implement, and standardize the use of performance testing and monitoring frameworks. • Utilize tools such as AppDynamics, JMeter, LoadRunner, and GCP-native APM for automated performance assessments. • Develop and maintain CI/CD-integrated automation pipelines for continuous performance validation. 4. Governance & Best Practices • Establish governance models and performance assessment frameworks to ensure uniform quality across all sprints. • Define and implement verification protocols and sprint-level performance gates to track improvements. • Promote ‘shift-left’ testing culture by embedding performance validation early in the development cycle. 5. Parallel Run & Validation • Lead the validation process between Mainframe and GCP systems to ensure performance parity and SLA compliance. • Plan, execute, and monitor performance during the parallel run phase to guarantee business continuity. 6. Performance Labs & Simulation • Design and manage dedicated performance labs that replicate airline workloads
