Senior Mobile Performance Tester

Senior Native Mobile Performance Testing Engineer

Primary Technologies: Apache JMeter | BlazeMeter | BrowserStack
Experience Required: 5–10 Years
Primary Specialization: Native Android and iOS Application Performance Engineering

Required Experience and Qualifications

• 5–10 years of overall experience in performance testing and performance engineering.
• Demonstrated hands-on performance testing experience with installed native Android and iOS applications, beyond mobile browser or mobile web testing.
• Advanced technical proficiency with Apache JMeter and BlazeMeter.
• Practical experience using BrowserStack for native mobile application testing on real devices.
• Hands-on experience developing Appium or equivalent native mobile automation scripts.
• Experience integrating protocol-level load testing with native application performance validation on physical devices.
• Ability to independently design, implement, and execute enterprise mobile performance testing solutions.
• Strong understanding of mobile application architecture, latency, throughput, concurrency, caching, asynchronous processing, and scalability.
• Experience working in Agile environments with cross-functional engineering teams.
• Excellent analytical, troubleshooting, documentation, and stakeholder communication skills.

Preferred Qualifications

• Traditional desktop or mobile web application performance testing, as a secondary skill.
• Experience with Tricentis NeoLoad or other commercial performance testing platforms.
• Android Studio Profiler, Apple Instruments, or equivalent native mobile profiling tools.
• Experience with Android/iOS application logs, crash diagnostics, and profiling.
• Experience with mobile network conditioning and network emulation.
• AWS or other enterprise cloud platforms.
• Service virtualization, production log analysis, and distributed systems.
• Familiarity with Android Kotlin/Java or iOS Swift/Objective-C development for performance diagnostics.

Web performance testing is a nice-to-have capability and must not substitute for native Android/iOS application performance engineering experience.

Expected Outcomes

The successful candidate will be expected to:

• Establish a repeatable and scalable native Android/iOS performance testing capability.
• Deliver reusable JMeter/BlazeMeter load-testing assets and BrowserStack native application automation scenarios.
• Enable coordinated backend load testing and real-device native application performance validation.
• Define meaningful native mobile performance benchmarks and acceptance criteria.
• Identify, isolate, and document application, device, network, and backend performance bottlenecks.
• Provide actionable recommendations to improve native application responsiveness, scalability, stability, and reliability.
• Integrate native mobile performance validation into Agile and CI/CD processes.
• Deliver evidence-based performance assessments supporting production release readiness.
