Senior Performance Engineer

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

3. Tools & Frameworks

4. Governance & Best Practices

5. Parallel Run & Validation

6. Performance Labs & Simulation

7. Metrics & Reporting

8. Stakeholder Management

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.
