The Integration Developer role works at the point where Operational Technology systems need to connect safely and perform in the real world. Day to day, you could be supporting OT integration across public transport projects, including rail control systems, communications, passenger information, safety systems and supporting digital infrastructure. The work includes integration specifications, interface control documents, technical designs, FAT, SAT, end-to-end testing, commissioning support, supplier engagement and risk monitoring. It is a strong fit for developers or engineers who understand OT and IT integration, like safety-critical environments, and can work closely with operational, engineering, safety and technology teams.
