Performance Testing Consultant (Mid Level)

As a seasoned Consultant in performance testing, you will be at the heart of ensuring our customers’ most critical applications are fast, stable, and ready to scale. You will collaborate closely with architects, developers, platform, infrastructure, and business stakeholders to transform performance requirements into actionable test strategies and engineering solutions. This role offers the opportunity to work on diverse, cloud native and enterprise systems, using leading tools like LoadRunner, Dynatrace, AppDynamics, and Splunk to uncover bottlenecks and drive measurable improvements. You will be expected to lead performance strategy discussions, clarify ambiguous requirements, and translate them into measurable workloads, SLAs/SLOs, KPIs, and success criteria. You’ll be encouraged to share your insights, mentor others, and continuously refine best practices. If you enjoy solving complex performance challenges, influencing technical direction, and partnering with teams to deliver reliable, high performing applications across the full technology stack, this role will give you both impact and room to grow.

Responsibilities

Design, plan, and execute end to end performance test strategies (load, stress, endurance, scalability) for complex enterprise and cloud based applications.

Develop, parameterize, and maintain robust LoadRunner scripts, scenarios, and workloads aligned with business usage patterns, including advanced correlation, parameterization, think time modeling, error handling, custom logic, and data driven frameworks.

Perform in depth performance analysis using Dynatrace and other monitoring tools to identify bottlenecks across application, database, network, and infrastructure layers.

Collaborate with architects, developers, platform, infrastructure, and operations teams to define performance scope, SLAs/SLOs, KPIs, and success criteria, interpret performance results, diagnose root causes, and recommend tuning and optimization strategies.

Lead performance engineering activities, including capacity planning, sizing, and performance modeling for on premise and cloud environments, with a strong focus on microservices, REST APIs, async workflows, and batch processing.

Conduct cloud performance testing across major platforms (e.g., autoscaling, elasticity, resilience), validating SLAs and non functional requirements, and evaluating limits/requests, node saturation, and cluster level constraints.

Prepare clear, data driven performance reports, dashboards, and presentations for technical and business stakeholders, communicating complex technical findings in a concise and business relevant manner.

Guide project teams on performance best practices throughout the SDLC and support shift left performance testing approaches, including early requirements clarification and performance risk identification.

Mentor junior team members in performance testing techniques, tools usage, and analysis methods, fostering a self driven, ownership mindset within the team.

Independently identify performance work items, define approaches, and execute performance engagements end to end, including test plan creation, scenario design, data modeling, and dashboard setup.

Drive performance analysis and bottleneck identification across the full stack (application, JVM/GC, database, infrastructure, and container platforms) without waiting for direction, providing concrete tuning recommendations.

Technical requirements

Education: Graduation in Computer Science, Information Technology, Engineering, or a related discipline.

3-5 years of hands on experience in performance testing and performance engineering for web or enterprise applications.

Strong expertise in LoadRunner for scripting, scenario design, execution, and analysis.

Proven experience in end to end Performance Testing (load, stress, endurance, spike) including test planning and execution.

Solid background in Performance Engineering, including bottleneck identification, tuning recommendations, and capacity considerations.

Practical experience using Dynatrace (or similar APM tools) for monitoring, tracing, and root cause analysis during performance tests.

Hands on experience with Cloud Performance Testing for applications hosted on public or private cloud environments.

Effective verbal and written communication skills to interact with cross functional and client teams.
