Performance Engineer - Performance Testing, JMeter, Load Runner, API Performance & Java/JVM

Scope: We provide 3PL customers with the integrated supply chain solution for planning, TMS, OMS & WMS. The 3PL PSR team works closely with QA, Development, DevOps, DBA, Solution Architect and Infrastructure teams to ensure applications meet performance and scalability requirements. The role requires both hands-on performance engineering and architectural understanding, ensuring scalable and future-ready implementations. The individual will be responsible for designing, planning, and executing performance, load, stress, endurance, and scalability testing for enterprise applications. Also, the individual will be responsible for analysing application behaviour and identify performance bottlenecks across application, database, infrastructure, and network layers.

Technical Environment: Performance Testing Tools: Jmeter API/Application: REST APIs, JSON/XML, HTTP/HTTPS, Web applications, Microservices, Postman Scripting & Development: JavaScript, Groovy, Python, Shell scripting Databases: Oracle, MariaDb; SQL query analysis and database performance analysis Database Performance: Oracle AWR/ASH, execution plans, SQL tuning, database CPU/memory/I/O analysis Application & JVM Monitoring: JVM, Garbage Collection (GC), Heap/Thread Dumps, JProfiler, Eclipse MAT or equivalent tools Infrastructure & Monitoring: Linux, Kubernetes, Docker, OCI/Azure, CPU/Memory/Disk/Network monitoring, Grafana, OEM DevOps/Agile: Git, Jenkins Cloud: OCI/Azure integrations Others: RDP/SSH, Linux command-line utilities, log analysis, performance profiling, capacity planning, and production performance monitoring.

What you’ll do: Design and execute performance, load, stress, endurance, and scalability tests for enterprise applications. Develop and maintain JMeter/API performance test scripts, workload models, test data, and execution scenarios. Analyse application performance across application, database, JVM, infrastructure, and network layers. Monitor system behaviour during load tests and identify CPU, memory, database, JVM, I/O, and response-time bottlenecks. Perform root-cause analysis of performance issues using application logs, monitoring tools, AWR/ASH reports, thread dumps, heap dumps, and GC logs. Work closely with Developers, QA, DBAs, DevOps, and Infrastructure teams to troubleshoot and resolve performance issues. Analyse test results and prepare performance reports, dashboards, and recommendations for stakeholders. Support capacity planning, scalability assessment, and production-readiness reviews. Identify opportunities to automate performance testing, monitoring, and reporting to improve efficiency and repeatability. Participate in release planning and provide performance assessment and recommendations for production deployment. Communicate performance findings, risks, and recommendations clearly to both technical and business stakeholders.

What we are looking for: Bachelor’s degree in computer science, IT, or related field. 1-3 years of experience in Performance Testing / Performance Engineering. Strong hands-on experience with JMeter and performance test scripting. Good understanding of load, stress, endurance, scalability, and volume testing . Strong experience in API performance testing using REST/HTTP, JSON/XML, and Postman. Good understanding of Java/JVM , including heap, threads, GC, and JVM tuning. Experience with JProfiler, Eclipse MAT, thread/heap dumps, and GC logs . Experience with Linux/Unix, shell scripting, and application/log analysis . Good knowledge of SQL and database performance , preferably Oracle, including AWR/ASH and execution plan analysis on OEM. Experience with Grafana, Prometheus, InfluxDB , or equivalent monitoring tools. Understanding of Kubernetes/containerized environments and exposure to OCI/Azure is preferred. Strong performance troubleshooting, root-cause analysis, analytical, and communication skills. Ability to work independently and manage multiple performance testing activities within timelines.
