Senior Software Development Engineer in Test (SDET)
About The Position
Although the formal title is Senior Test Automation Engineer, this is a Senior Software Development Engineer in Test (SDET) role requiring hands-on software development expertise in JavaScript, TypeScript, and/or C#, plus working knowledge of SQL. The role treats test automation as a software engineering discipline and focuses on designing, building, and maintaining scalable automated testing frameworks for enterprise applications. The position establishes and owns automated quality engineering capabilities for the SPM Cloud platform. Initially, the role will learn the testing framework, release processes, validation approaches, and quality controls used during implementation while helping prepare STERIS to assume operational ownership. As the platform transitions to internal management, the role will define and execute its automated testing strategy, quality governance framework, release assurance processes, test automation architecture, and quality engineering standards. It will contribute to software quality, reliability, scalability, and delivery excellence across future platform initiatives. The position is located in Vernon Hills, Illinois, with an opportunity for a hybrid work schedule. Candidates currently within commuting distance are preferred.
Requirements
- Bachelor's degree in Computer Science, Engineering, Information Technology, or a related field.
- At least 8 years of professional software testing, quality engineering, test automation, or related software engineering experience.
- Experience building and maintaining automated test frameworks for enterprise software applications.
- Strong experience with Playwright, Cypress, Selenium, or equivalent modern test automation frameworks.
- Experience developing automated tests using TypeScript, JavaScript, C#, or similar programming languages.
- Experience testing REST APIs, web services, integrations, and distributed applications.
- Working knowledge of SQL, database validation techniques, and Git-based source control workflows.
- Experience integrating automated testing into CI/CD pipelines and Agile software delivery environments.
- Experience supporting production applications through defect triage, troubleshooting, release validation, and root cause analysis.
Nice To Haves
