## Description

Take on a new challenge and apply your engineering expertise in a cutting-edge field. You'll work alongside collaborative and dedicated teammates.

You'll play a critical role in supporting the deployment and continuous improvement of mainline signalling systems. Day-to-day, you'll work closely with teams across the business (deployment teams, engineers, project teams, and customers), conduct root cause analyses, and help define best practices for continuous improvement.

You'll specifically take care of providing technical hotline support for trackside signalling solutions, but also contribute to knowledge sharing and the creation of reusable troubleshooting resources.

We'll look to you for:

 * Serving as the technical point of reference for hotline support on trackside signalling solutions
 * Reviewing issues raised by deployment teams, identifying recurring trends, and providing clear answers or escalation inputs when needed
 * Carrying out root cause analysis and fault diagnosis using structured methods
 * Recording issues, solutions, lessons learned, and troubleshooting steps in a clear, concise, and rigorous way
 * Collaborating with engineers, stakeholders, project teams, and customers to ensure reliable support and professional communication
 * Supporting continuous improvement through post-incident reviews, knowledge sharing, and the definition of best practices
