Senior Performance Engineer

Job Description 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 and stress conditions. Simulate critical TPF transaction volumes, API latencies, and throughput benchmarks for accurate validation. 7. Metrics & Reporting Define quantitative KPIs and analytical measures to assess performance maturity and stability. Build performance dashboards and reports to communicate metrics to senior stakeholders and leadership. 8. Stakeholder Management Partner with enterprise architects, DevOps leaders, and product managers to align performance strategies with overall transformation goals. Present regular updates, bottleneck findings, and improvement recommendations to steering committees and executives. Required Skills and Experience The ideal candidate should have deep expertise in TPF systems, airline transaction processing, and GCP cloud performance optimization. Hands-on experience in performance tuning, profiling, and root cause analysis across distributed environments is essential. Proficiency with tools such as AppDynamics, Dynatrace, JMeter, or Gatling is required, alongside familiarity with Terraform, Kubernetes, and CI/CD-based automation. Experience designing GCP performance architectures involving Cloud Run, Compute Engine, Pub/Sub, and Cloud Monitoring is highly preferred. The candidate should be capable of driving modernization initiatives, defining acceptance criteria within agile sprints, and mentoring technical teams on performance excellence. Qualifications Bachelor's or master's degree in computer science, Information Systems, or related field. 20+ years experience professional, with a minimum of 12 years of experience in performance engineering, with at least 5 years at an architect level in large-scale transformation programs. Experience in Airlines or Travel domain preferred. Certifications in GCP, Performance Engineering, or DevOps will be advantageous. Location Bangalore Employment Type Full-time | Long-term engagement (3+ years) Assumptions Made The position is part of a global airline's Mainframe to GCP cloud transformation program involving more than 90 scrum teams. The architect will lead performance governance during the parallel-run phase between mainframe and cloud, focusing on response time optimization and tool-based automation. Tools such as AppDynamics, JMeter, and Terraform will be part of the ecosystem. The project demands near real-time response times critical to airline operational systems.
