• Develop and execute performance, load, and stress test scenarios, ensuring integration into CI/CD pipelines for continuous performance validation.
• Collaborate with developers, QA teams, and operations to embed performance testing and optimization practices into daily workflows.
• Analyze system behavior under varying conditions, identify bottlenecks, and provide actionable recommendations for improvement.
• Troubleshoot and enhance existing performance test scripts and frameworks to improve efficiency, maintainability, and accuracy.
• Promote best practices in performance engineering and contribute to overall quality and system optimization across the organization.

Qualifications

• Strong experience in performance testing and software quality assurance – you understand different levels of performance validation and what it takes to ensure scalability and responsiveness.
• Previous experience in performance testing within a product development organization, with a strong appreciation for customer experience and the ability to translate real‑world performance issues into effective test strategies.
• Hands‑on experience with performance testing tools such as Robot Framework, JMeter, Ranorex, Gatling, or LoadRunner, and familiarity with monitoring and profiling tools (e.g., Application Insights, Grafana, Prometheus).
• Experience in scripting languages like JavaScript or Python, and solid understanding of Git and CI/CD tools such as Azure DevOps or Jenkins.
• Ability to analyze system behavior under load, identify bottlenecks, and provide actionable recommendations for optimization.
• Interest and motivation to work in agile software development, collaborating closely with developers, QA, and operations teams.
• Good communication skills and fluent language skills in Finnish and English, enabling clear reporting and customer‑focused discussions.

Beneficial Experience

• Seasoned professional looking for new challenges.
• Experience in testing large‑scale, business‑critical systems, especially in regulated environments.
• Familiarity with healthcare and welfare sector regulations and how they impact software testing and compliance.
• Strong willingness to deepen technical expertise in performance testing, continuously improve as a QA professional, and collaborate effectively as a team player.
