The System Test Engineer is responsible for the development, maintenance, and execution of test cases to support Design Verification, Design Validation, and Usability Engineering activities for products designed and developed by the company. A System Test Engineer reads and interprets requirements documents and other design documentation and interacts with design engineers to ensure test cases properly verify the design requirements and support validation of applicable user needs and intended uses. A System Test Engineer also reads, understands, and executes plans for Design Verification, Design Validation, and Usability Engineering and contributes to associated reports summarizing the testing efforts. A System Test Engineer will become familiar with applicable international standards associated with medical device development and quality management (ISO 13485, ISO 14971, IEC 62304, and IEC 62366) and can also support the Quality department with other work when workload permits. About the Role * Develop and recommend verification and validation strategies, including test methods, test levels, sequencing, required environments, and appropriate use of analysis, inspection, demonstration, and testing. * Develop and maintain plans for Design Verification, Design Validation, and Usability Engineering activities for products under development. * Review and critique all architecture, requirements, and design documents associated with products under development. * Independently derive effective and efficient test cases to verify requirements and validate applicable user needs and intended uses for the products under development. * Execute test cases on assigned systems and accurately record the results. * Identify, document, and characterize defects discovered during test execution with sufficient technical detail and reproducibility information to assist in troubleshooting and allow further evaluation by the development team. * Establish and maintain bidirectional traceability between requirements, test cases, test results, and risk control measures. * Train to and adhere to all relevant SOPs, work instructions, and company policies as part of TAE Life Science's Quality Management System. * Create and maintain Quality Management System documents concerning Design Controls. * Coordinate with development teams to ensure current Design Controls procedures, work instructions, and templates are sufficient to meet their needs. * Represent the Quality department in meetings, design reviews, and/or discussions involving testing or design controls. ## Related Videos - [The Algorithm That Nearly Killed Me: When Testing Isn't Enough](https://www.wearedevelopers.com/videos/2110-the-algorithm-that-nearly-killed-me-when-testing-isn-t-enough) - [How To Test A Ball of Mud](https://www.wearedevelopers.com/videos/173-how-to-test-a-ball-of-mud) - [Introduction to Azure Machine Learning](https://www.wearedevelopers.com/videos/368-introduction-to-azure-machine-learning) - [Enabling intelligent logistics automation: home-grown Industrial IoT platform at Austrian Post](https://www.wearedevelopers.com/videos/2018-enabling-intelligent-logistics-automation-home-grown-industrial-iot-platform-at-austrian-post) - [How I Built QA from Scratch in a Scaling Startup - no fluff real life story](https://www.wearedevelopers.com/videos/2041-how-i-built-qa-from-scratch-in-a-scaling-startup-no-fluff-real-life-story) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [What is a Test Plan: Guide to Test Planning](https://www.wearedevelopers.com/magazine/191-what-is-a-test-plan-guide-to-test-planning) - [How to create a test plan for software testing](https://www.wearedevelopers.com/magazine/56-how-to-create-a-test-plan-for-software-testing) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard)
