Performance Tester

Vertere Global Solutions, Inc.; Taguig; Ibrido; PHP 600.000 - 1.000.000; Tempo pieno

Descrizione del lavoro

Vertere Global Solutions, Inc. is seeking a Performance Tester to join a small, cross-functional quality team embedded with a development squad. You will specialize in speed, scalability, and stability, ensuring applications hold up under real-world load before release.

You will work with QA Lead, Manual/Functional Testers, QA Automation Engineers, and API Testers to bring a performance lens to every release and help catch bottlenecks early rather than in production.

Competenze

• Bachelor's degree in Computer Science, IT, Engineering, or equivalent experience.
• 3–5 years of software testing experience, with at least 2 years focused on performance testing.
• Hands-on experience with at least one major load testing tool (JMeter, k6, Gatling, or LoadRunner).
• Scripting skills in Java, JavaScript/TypeScript, Python, Groovy, or Scala.
• Solid understanding of HTTP/HTTPS, REST APIs, web architecture, and client-server systems.
• Working knowledge of SQL and database performance basics.
• Experience reading performance metrics: response time percentiles, throughput, error rates, CPU, memory, and I/O.
• Familiarity with Agile/Scrum and the software development lifecycle.
• Experience with APM and observability tools (Dynatrace, New Relic, AppDynamics, Datadog, Grafana).
• Exposure to cloud platforms (AWS, Azure, or GCP) and distributed or cloud-based load generation.
• Knowledge of containers and orchestration (Docker, Kubernetes).
• Experience testing microservices, message queues, or mobile backends.
• Basic understanding of front-end performance (Core Web Vitals, Lighthouse).
• ISTQB Performance Testing or related certification

Mansioni

• Gather non-functional requirements (response times, throughput, concurrency, SLAs) from product owners and the QA Lead.
• Design performance test strategies and plans covering load, stress, spike, soak/endurance, and scalability testing.
• Build realistic workload models based on production usage patterns and business scenarios.
• Develop, maintain, and parameterize performance test scripts using tools such as JMeter, k6, Gatling, or LoadRunner.
• Prepare and manage test data and test environments for performance runs.
• Execute performance tests and monitor system behavior during runs.
• Analyze results to identify bottlenecks across application, database, network, and infrastructure layers.
• Use monitoring and APM tools (e.g., Grafana, Prometheus, Dynatrace, New Relic, Datadog) to correlate metrics and pinpoint root causes.
• Produce clear reports with findings, risks, and recommendations for both technical and non-technical stakeholders.
• Integrate performance tests into CI/CD pipelines (e.g., Jenkins, GitHub Actions, Azure DevOps) with the Automation Engineers.

Descrizione del lavoro

Summary

We are looking for a Performance Tester to join in our team: a small, cross-functional quality team embedded with a development squad. You will be a specialist for speed, scalability, and stability, making sure our applications hold up under real-world load before they reach users. You will work alongside the QA Lead, Manual/Functional Testers, QA Automation Engineers, and API Testers, bringing a performance lens to every release and helping the team catch bottlenecks early rather than in production.

Key responsibilities

• Gather non-functional requirements (response times, throughput, concurrency, SLAs) from product owners and the QA Lead.
