• Strong hands-on experience with performance testing, including the ability to start performance testing for a component from scratch
• Strong understanding of system architecture and how application, infrastructure, cloud, and network components affect performance
• Expertise in performance analysis, including network latency tuning, caching strategies, and database connection pooling
• Experience with capacity planning and cost-vs-performance analysis, with FinOps awareness
• Strong analytical and problem-solving skills, with the ability to investigate performance issues and determine their root causes
• Programming or scripting skills, preferably with Python or Scala
• Hands-on experience with AWS or another major cloud platform
• Strong technical communication and collaboration skills

🧩Key responsibilities and your contribution

In this role, you'll lead performance testing for complex cloud-based systems, focusing on scalability, resilience, and deep performance analysis.

• Define and set up performance testing approaches for cloud-native components and architectures (microservices, serverless, containers)
• Test and validate cloud elasticity, auto-scaling policies, failover, and self-healing mechanisms under peak load
• Perform deep-dive root-cause analysis (heap dumps, thread dumps, memory leak identification, and database query optimization)
• Establish Non-Functional Requirements (NFRs), SLAs, SLOs, and Error Budgets with product managers
• Translate business and technical requirements into performance-testing plans, defining testing scope, test scenarios, and relevant metrics
• Analyze performance results and system behavior to identify bottlenecks, determine root causes, and recommend improvements
