Onsite Engineer (L2) at CDW

This role is ideal for a versatile, mid-level Systems Engineer who enjoys hands-on hardware work and has a deep interest in supporting critical infrastructure. Unlike standard "deskside" roles, this position focuses on high-stakes enterprise systems, requiring someone comfortable working with everything from modern servers to legacy mainframe and tape storage technology. Located onsite in Southampton at a client facility, you will be responsible for the reliability of air traffic control infrastructure. This is a unique opportunity to work with an incredibly diverse tech stack—including AIX, RedHat, and OS2 Warp—where your electro-mechanical skills and ability to troubleshoot bespoke equipment are just as important as your software knowledge. **You might be a good fit if you...** * Have experience supporting IBM Mainframes, DASD storage, or enterprise-level tape systems. * Are comfortable troubleshooting a mix of modern Linux/Windows environments and legacy systems like DOS or OS2. * Possess tactile technical skills, such as soldering and electro-mechanical repair for custom hardware. * Thrive in mission-critical environments where attention to detail and creative problem-solving are vital.
