Senior DevOps Engineer (REF4863S)

The Public Transport (ÖPNV) department provides innovative, full-service solutions for the public transport sector, supporting partners in their journey towards digitalization. With expertise in Digital Infrastructure, Digital Transport Operation, and Digital Passenger Experience, we enable public transport providers to deliver safe, efficient, and passenger-focused mobility solutions.

Our areas include the OBU (On-Board Unit) development, which is an integrated software and hardware solutions designed for public transport vehicles, such as buses and trams, to enhance operational efficiency and connectivity for Bochum-Gelsenkirchener Straßenbahnen AG (BOGESTRA) who is member of the KÖR (Kooperation östliches Ruhrgebiet: Eastern Ruhr Area Cooperation). The solution is used in hundreds of vehicles across Germany and is used by thousands. Heavily relying on the T-Systems own TETRA and ITCS solutions, we are developing everything in close contact with the customer to fit users needs.

By combining technological innovation with comprehensive consulting and project management expertise, we provide end-to-end solutions that modernize public transport systems, enhance operational performance, and improve passenger experience.
