Sr Software Testing Engineer Jobs in California (NOW HIRING)

Position Summary:

Responsibilities:

• Design, develop, and maintain automated test frameworks for web, mobile, API, service-level, integration, and end-to-end testing.
• Build reliable, reusable, scalable, and maintainable automated tests using modern engineering practices.
• Develop automation strategies that improve test coverage, reduce manual testing dependency, and increase release confidence.
• Create and maintain automated regression, smoke, functional, integration, and workflow validation suites.
• Analyze automation failures, identify root causes, reduce test flakiness, and improve automation reliability.
• Evaluate and recommend commercial and open-source testing tools, frameworks, and libraries based on project needs.
• Use AI-assisted engineering tools where appropriate to accelerate test creation, framework development, defect analysis, and productivity.

• Design and implement automated tests for APIs, services, databases, third-party integrations, and complex business workflows.
• Validate application behavior beyond the user interface, including service responses, data transformations, event flows, and downstream system impacts.
• Use SQL and other validation techniques to confirm data accuracy, consistency, and integrity across systems.
• Create test data strategies to support automation, regression testing, integration testing, and production-like validation.
• Partner with Engineering and Architecture teams to identify quality risks in system design, data flows, and integration patterns.

• Integrate automated tests into CI/CD pipelines and ensure test results provide meaningful feedback for build, deployment, and release decisions.
• Collaborate with DevOps and Engineering teams to define quality gates, pipeline validation, and environment promotion criteria.
• Support release-level validation by ensuring automated tests reflect actual release scope, dependencies, integrations, and business workflows.
• Participate in release readiness activities by providing clear test results, risk indicators, defect analysis, and quality recommendations.
• Support planned production releases and critical off-hours deployments as needed, in alignment with team release schedules.

• Investigate complex application, automation, data, integration, and environment issues.
• Use logs, metrics, traces, monitoring tools, and application telemetry to troubleshoot failures and improve test coverage.
• Partner with Engineering, DevOps, QA, and business teams to diagnose defects and validate fixes.
• Contribute to root cause analysis and identify opportunities to prevent similar issues in future releases.
• Validate application behavior under realistic conditions, including dependency failures, latency, service degradation, and recovery scenarios.

• Work with business and technical stakeholders to understand requirements and ensure functional and technical validation is built into the delivery process.
• Review requirements, designs, user stories, acceptance criteria, and technical changes to identify testing needs and quality risks.
• Coach and mentor QA engineers, SDETs, and development teams on test automation, testability, framework usage, and quality engineering practices.
• Promote engineering practices that make applications more testable, observable, reliable, and maintainable.
• Proactively identify automation gaps, process improvements, quality risks, and opportunities to improve delivery outcomes.
• Maintain strong responsiveness and dependability when supporting team needs, stakeholder questions, release validation, and urgent quality issues.

Requirements:

• Minimum seven (7)+ years of experience in software testing, test automation, software development, or quality engineering.
• Strong hands-on experience designing and developing automated tests and test frameworks.

• Experience with modern automation tools and frameworks such as Selenium, Playwright, Cypress, Appium, NUnit, xUnit, JUnit, TestNG, SpecFlow, Cucumber, Postman/Newman, REST Assured, or similar.
• Strong experience with API testing, service-level validation, integration testing, and end-to-end workflow validation.
• Strong SQL and data validation experience.
• Experience integrating automated tests into CI/CD pipelines using tools such as Azure DevOps, GitHub Actions, Jenkins, TeamCity, or similar.
• Experience analyzing test failures, troubleshooting complex defects, and improving automation reliability.
• Experience with test management, defect tracking, and collaboration tools such as JIRA, Azure DevOps, Confluence, or similar.
• Strong understanding of software development lifecycle practices, agile delivery, release validation, and quality engineering principles.
• Ability to work collaboratively in a team environment and communicate clearly with technical and non-technical stakeholders.
• Strong sense of ownership, accountability, and commitment to delivering a reliable user experience.
