Junior Automation Testing Using Selenium Jobs in Chicago, IL

PDF Solutions is redefining the way the semiconductor industry approaches data, analytics, and experience design. As part of our journey, we’re building Next gen platform — a modern, human-centered analytics platform. We believe design systems aren’t just about consistency — they’re about scalability, collaboration, and performance.

The Senior QA Automation Engineer will play a critical role in ensuring the accuracy, reliability, security, and performance of our AI-enabled integration platform.

This role goes beyond traditional UI testing. You will design and implement automation frameworks for backend services, cloud-native deployments, and machine learning–driven applications. You will be deeply involved in validating data pipelines, testing ML forecasts against historical datasets, and ensuring platform readiness across multi-cloud and containerized environments.

The ideal candidate brings a strong automation-first mindset, hands-on experience with ML application testing, and the ability to work closely with engineering, data science, and DevOps teams to embed quality throughout the SDLC.

• Design, develop, and maintain scalable automation frameworks using Python, Java, Selenium, and API testing tools.
• Implement automated testing for backend services, data pipelines, and cloud-native microservices.
• Build reusable test components for regression, integration, and performance testing.

AI / ML Application Validation

• Validate machine learning models by evaluating prediction accuracy against historical and real-world datasets.
• Design test strategies for forecasting, anomaly detection, and analytics pipelines used in integration platforms.

Cloud, Container & DevOps Testing

• Test applications deployed as Docker containers across multiple cloud environments.
• Contribute to Helm charts, deployment pipelines, and test environments.
• Integrate automated tests into CI/CD pipelines and DevOps workflows.

Security, Reliability & Observability

• Perform security testing using tools such as SQLMap, OWASP ZAP, and vulnerability scanners.
• Validate system reliability, fault tolerance, and recovery scenarios.
• Support observability testing using logs, metrics, and monitoring tools (e.g., Prometheus, Grafana).

Quality Leadership

• Advocate for quality-driven engineering practices and shift-left testing strategies.
• Collaborate with cross-functional teams to define test strategies aligned with product and business goals.
• Mentor junior QA engineers and contribute to continuous improvement of QA standards.

Must-Have Skills & Experience
