(Senior) Test and DevOps Engineer
You want to implement test automation not only but fundamentally – with CI/CD pipelines, HIL integration and freedom to anchor quality systemically Do you know the feeling when tests are manually clicked through, even though you know exactly that a sophisticated test infrastructure with automated workflows would create real security? If hardware-in-the-loop tests remain in the laboratory island solutions instead of being integrated in CI/CD pipelines? If Jenkins pipelines are missing and container deployments are future music? Stop it! We at TWK have been developing and producing customer-specific sensors for plant and mechanical engineering for over 60 years in the growth market of measurement and automation technology. Functional safety for man and machine is our requirement – and right there you come into play. As a (Senior) test engineer and DevOps engineerin, we get exactly what is often missing elsewhere: the free space, a test automation infrastructure for embedded systems to develop and design from scratch. An interdisciplinary development team waiting to benefit from your DevOps expert. You build CI/CD pipelines with Jenkins and Gerrit, integrierst HIL test systems in automated workflows and managstly containerized test environments – not as a secondary task, but as your core responsibility. At the next time, we will look for you in full time to strengthen our site in Wedel. About the place We are looking for an (Senior) test and DevOps engineer*in that guides the design, development and maintenance of an advanced test automation infrastructure for embedded devices.
