We are looking for a Performance Engineer to contribute to the implementation and execution of the performance engineering approach for our applications and supporting services.

In this role, you will validate Non-Functional Requirements (NFRs), including response time, throughput, scalability, stability, and resource engineer will work closely with development, Dev

SecOps, architecture, and product teams to help identify performance risks early, build automated performance testing capabilities, analyze system behavior under realistic workloads, and ensure applications meet agreed performance and scalability targets before production release.

Responsibilities

Contribute to the performance testing and performance engineering strategy based on application architecture, business usage patterns, and NFRsHelp translate business and technical NFRs into measurable performance acceptance criteria, test scenarios, workload models, and success thresholds

Execute load, stress, spike, endurance/soak, scalability, and capacity tests across web applications, APIs, and backend services

Develop and maintain automated performance test scripts using existing performance testing frameworks

Test the performance of HTTP/REST and gRPC-based APIs and services

Build workload models based on expected user volumes, concurrency, transaction patterns, and production-like behavior

Analyze performance across the application stack, including frontend, APIs, services, databases, caching layers, infrastructure, and third-party dependencies

Identify performance bottlenecks and participate in root-cause analysis using application, infrastructure, database, and observability data

Validate application behavior under normal, peak, and sustained workloads

Measure key performance indicators such as response time, latency, throughput, error rate, concurrency, CPU,



memory, network utilization, and database performance

Integrate performance tests into CI/CD pipelines to support continuous performance validation and detect regressions early

Help establish performance baselines and track performance trends across releases

Collaborate with software engineers and Dev

SecOps teams to validate performance optimizations

Produce clear performance test reports, highlight risks, and communicate whether agreed NFRs and release criteria have been met
