Job Overview :

We are seeking a talented and experienced Performance Test Lead to join our dynamic team. The ideal candidate will have a strong background in performance testing, automation frameworks, and modern testing methodologies, including expertise in Cypress, K6, and BDD. As a Performance Test Lead, you will be responsible for defining, designing, and executing performance tests across web and API applications, with a focus on automation, scalability, and system reliability.

This role offers an exciting opportunity to lead a team of testers while driving the performance testing strategy and ensuring high-quality software releases.

Key Responsibilities :

Test Strategy & Leadership :

- Define and implement performance testing strategies and best practices across multiple projects.

- Lead and mentor a team of performance engineers and testers, providing guidance on test execution, troubleshooting, and results interpretation.

- Collaborate with developers, DevOps, and product teams to define test requirements and integrate performance testing into the CI/CD pipeline.

Performance Testing :

- Design and execute performance, load, stress, and scalability tests for web applications, APIs, and microservices.

- Use K6 for performance testing of APIs and microservices, ensuring that load, stress, and endurance testing are conducted effectively.

- Implement Cypress for integration testing with a focus on end-to-end automated testing to ensure smooth performance during normal and peak load conditions.

Automation and Tools :

- Develop and maintain automated performance test scripts using K6, Cypress, and other related tools.

- Integrate performance tests into the CI/CD pipeline using automation tools like Jenkins, GitLab CI, or Azure DevOps.

- Leverage BDD frameworks (e.g., Cucumber, SpecFlow) to write performance test cases that are readable and maintainable by both technical and non-technical stakeholders.

Performance Analysis & Reporting :

- Analyze test results to identify performance bottlenecks, scalability issues, and areas for improvement.

- Provide detailed, actionable reports with recommendations for optimizing performance, including insights on load distribution, throughput, response times, and resource utilization.

- Work with the development team to debug and resolve performance issues and defects.

Collaboration and Continuous Improvement :

- Collaborate with product managers, engineers, and stakeholders to understand performance requirements and ensure that testing is aligned with business objectives.

- Keep up to date with the latest trends and best practices in performance testing, automation, and related technologies.

- Drive a culture of continuous improvement by promoting performance testing early in the development lifecycle.

Required Qualifications :

- Experience : 8+ years of experience in performance testing and test automation.

- Proven experience with Cypress for end-to-end and UI performance testing.

- Expertise in K6 or similar tools (e.g., JMeter, Gatling) for API and load testing.

- Strong experience with BDD frameworks such as Cucumber, SpecFlow, or Behave for writing performance test cases.

Technical Skills :

- Solid knowledge of JavaScript, Node.js, and TypeScript for test automation and scripting.

- Familiarity with performance testing tools and scripting languages (e.g., K6 scripting, JavaScript, JSON).

- Experience with test automation frameworks like Jest, Mocha, or Chai for functional and performance testing.

- Understanding of web technologies such as HTTP, WebSockets, REST APIs, JSON, etc.

- Familiarity with CI/CD tools (e.g., Jenkins, GitLab CI, Azure DevOps) and their integration with performance testing frameworks.

Soft Skills :

- Strong analytical and problem-solving skills with the ability to identify root causes and propose solutions.

- Excellent communication skills with the ability to explain technical issues to both technical and non-technical stakeholders.

- Experience working in an Agile environment with cross-functional teams.

- Ability to lead and mentor a team of performance testers.

Desired Qualifications :

- Experience with cloud-based testing platforms (e.g., AWS, Azure, Google Cloud).

- Familiarity with containerization and orchestration tools (e.g., Docker, Kubernetes).

- Knowledge of distributed systems and microservices architectures.

- Certifications in performance testing (e.g., LoadRunner, K6 certifications) or BDD frameworks.
