Performance Test Engineer

Role Overview

We are looking for a strong Performance Testing Engineer to lead performance, load, stress, and endurance testing efforts across enterprise applications. The ideal candidate combines deep performance engineering expertise with hands-on API testing and UI automation skills, enabling end-to-end quality validation beyond tool execution.

Key Responsibilities

• Design, script, and execute performance, load, stress, and endurance tests using JMeter and/or LoadRunner.
• Analyze throughput, latency, response time, and TPS metrics to identify system bottlenecks and perform root cause analysis.
• Monitor and diagnose application performance under load, correlating results with system/application architecture behavior.
• Validate REST APIs as part of performance and functional testing engagements, ensuring request/response integrity and correct authentication handling.
• Build and maintain UI automation scripts/frameworks using Selenium WebDriver with TestNG/JUnit and Page Object Model design.
• Write, debug, and enhance automation scripts and frameworks independently using Java (and/or Python).
• Present performance test findings, bottleneck analysis, and automation framework architecture clearly to technical and business stakeholders.

Skills

• Performance Testing & Engineering – Strong hands-on expertise with JMeter and/or LoadRunner to design and execute performance, load, stress, and endurance tests, with deep understanding of throughput, latency, TPS, bottleneck identification, and root cause analysis.
• API Testing – Solid grasp of REST APIs, HTTP methods, status codes, and authentication mechanisms (OAuth, Bearer Token), with hands-on experience in Postman, REST Assured, and Swagger/OpenAPI for request/response validation.
• UI Automation Testing – Proficient in Selenium WebDriver with TestNG/JUnit, Page Object Model, and data-driven/keyword-driven framework design and best practices.
• Coding/Programming Proficiency – Intermediate-to-strong coding skills in Java (preferred) and/or Python, with the ability to write, debug, and enhance automation scripts and frameworks independently.
• Performance Diagnostics & Root Cause Analysis – Ability to analyze application architecture and system behavior under load, going beyond tool execution to troubleshoot bottlenecks end-to-end.
• Communication & Stakeholder Articulation – Strong ability to explain project experience, framework architecture, testing approach, and troubleshooting analysis clearly (minimum proficiency level 3/5).

Ideal Candidate Profile

• Strong Performance Testing Engineer (JMeter/LoadRunner)
• Hands-on API Testing experience
• Solid UI Automation knowledge (Selenium-based)
• Good coding skills (Java/Python)
• Able to analyze performance bottlenecks beyond tool execution
• Good communication and articulation skills
