Job Description

Job Summary:

We are seeking a skilled and self-driven Performance Tester to join our team in Telco domain. The Performance Tester will be responsible for designing, executing, and analyzing performance tests using tools such as JMeter to ensure that systems can handle high traffic, meet performance benchmarks, and remain stable under load. This role requires working independently, proactively identifying performance bottlenecks, and collaborating with cross-functional teams to optimize system performance. The ideal candidate has prior experience working on large-scale projects involving complex system integrations.

Requirements

Key Responsibilities:

Design and execute performance tests (load, stress, endurance) using JMeter, LoadRunner, and IBM Rational Performance Tester. Analyse test results to identify performance bottlenecks (CPU, memory, network, database, APIs). Establish performance benchmarks and validate system behavior under peak load. Collaborate with development, QA, infrastructure, and DevOps teams to support performance optimisation. Prepare clear performance test reports with findings and recommendations. Support performance testing across integrated systems (APIs, middleware, third-party services, databases).

Qualifications:

Educational Background:

Bachelor's degree in Computer Science, Information Technology, or a related discipline.

Experience:

At least 2 years of hands-on experience in performance testing, specifically using JMeter in complex and integrated Telco systems or similarly large-scale environments.
