Performance Engineering & Optimization
- Identify, analyse, and resolve performance bottlenecks across application, middleware, and infrastructure layers.
- Conduct deep-dive analysis into CPU, memory, I/O, network, and latency issues.
- Drive performance tuning initiatives for high-throughput and low-latency systems.
- Establish performance benchmarks and define SLAs/SLOs for critical services.

Debugging & Troubleshooting at Scale
- Lead root cause analysis for production performance issues and outages.
- Debug complex issues in distributed environments involving multiple services and dependencies.
- Analyse thread dumps, heap dumps, GC logs, and profiling data to diagnose issues.
- Work closely with DevOps and Arch teams for arriving at Scalable Solutions/Fix.





System Design & Architecture
- Provide design recommendations with a robust focus on Performance, Scalability and Resilience.
- Evaluate trade-offs in distributed system design (e.g., consistency vs availability, throughput vs latency).
- Influence architecture decisions for microservices, event-driven systems, and data pipelines.
- Ensure systems are designed to handle large-scale workloads efficiently.

Benchmarking & Capacity Planning
- Design and execute performance tests (load, stress, endurance, spike testing).
- Build benchmarking frameworks for new and existing features.
- Perform capacity planning and forecasting for infrastructure and application growth.
- Validate system behaviour under peak and failure scenarios.

Feature Development at Scale
- Contribute to development of new features with performance considerations from design to implementation.
- Ensure efficient resource
