Explore Test Engineer II jobs and discover a pivotal career at the intersection of software development, quality assurance, and systems validation. A Test Engineer II is a mid-level professional responsible for ensuring the functionality, reliability, and performance of products, which can range from software applications to complex hardware-software integrated systems. This role moves beyond basic execution to involve strategic planning, design, and implementation of sophisticated testing solutions. Professionals in these jobs typically own the end-to-end quality process for components or subsystems. Common responsibilities include designing and developing detailed test plans, cases, and strategies based on product specifications. A core duty is the creation and maintenance of robust automated test frameworks and scripts using languages like Python, Java, JavaScript, or TypeScript, and tools such as Selenium, Playwright, or Appium. They build and utilize specialized testing tooling, fixtures, and apparatuses. Integrating these automated tests into Continuous Integration and Continuous Deployment (CI/CD) pipelines using tools like Jenkins, GitLab CI, or Azure DevOps is standard practice to enable early and frequent validation. They execute a mix of automated and manual tests, including functional, regression, integration, and performance testing. Collaboration is key; Test Engineers II work closely with development, product, and other cross-functional teams to identify defects early, participate in design reviews, and advocate for quality throughout the development lifecycle. They also analyze test results, report on metrics like test coverage and defect trends, and provide actionable insights to stakeholders. Typical skills and requirements for Test Engineer II jobs include a bachelor’s degree in Computer Science, Electrical Engineering, or a related field, coupled with 2-5 years of hands-on experience in testing or development. Strong analytical and problem-solving skills are essential. Proficiency in at least one programming language for automation and scripting is a must, alongside a solid understanding of software testing methodologies, SDLC, and Agile/Scrum practices. Experience with version control systems like Git is expected. Desirable knowledge areas often include API testing, basic security testing concepts, performance benchmarking, and an understanding of system architecture. Excellent communication skills are vital for documenting processes, reporting defects clearly, and collaborating effectively within teams. For those seeking a challenging and technical career focused on building quality into products, Test Engineer II jobs offer a perfect blend of hands-on technical work, strategic planning, and collaborative problem-solving in a dynamic engineering environment.
