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

Overview

• 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.
• 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.
