## About the Role Do you want to help ensure that the railways of the future function safely and reliably, and work with safety-critical systems that affect thousands of people every day? We are now looking for a Development Test Engineer to join one of Sweden's most advanced technical fields. The railway industry is facing major investments and extensive technical development. We are looking for a Development Test Engineer who wants to verify software that controls everything from interlockings and switches to barriers and signaling systems – solutions that contribute daily to safer, more efficient, and more sustainable railway traffic. Here you get the opportunity to work with complex technical systems in an industry that plays a central role in the green transition. As a Development Test Engineer, you will become part of a team responsible for verification and testing of software within the railway's signaling systems. The team works with safety-critical systems where quality and reliability are crucial. The role is broad and combines technical analysis with the development of test environments and automated tests. ## Responsibilities You will work in an environment with simulators, communication interfaces, and internal test tools used to verify that complex railway systems function according to requirements and safety standards. You will have the opportunity to work with technology that makes a real difference. The railway industry is growing rapidly and plays a central role in future sustainable transport systems. You will work with large, complex, and society-critical systems where software, hardware, and automation interact.
