Your work will directly impact global transit networks, ensuring the highest stability, interoperability, and long-term maintainability for mission-critical operations.
You’ll make a difference by
• Analyse customer, system, product, and cybersecurity requirements and translate them into platform architectures, technical specifications, bills of materials, equipment layouts, network and storage designs, redundancy concepts, and verifiable design decisions. • Design robust, reliable, resilient, and maintainable infrastructure platforms for critical railway solutions, primarily across physical and virtualised environments and, where applicable, integrate containerised components delivered by specialist teams. • Select, size, configure, integrate, and administer enterprise and industrial equipment, including rack-mounted and specialised hardware, servers, operator workstations, network devices, SAN and NAS storage, Linux and Windows operating systems, virtualisation platforms, middleware, and SQL databases. • Develop reliable, repeatable, appropriately automated, and version-controlled mechanisms for platform installation, configuration, deployment, updating, backup, and recovery, suited to long-lifecycle industrial systems. • Build and maintain representative pre-production and validation environments, and apply platform security practices including operating-system hardening, SELinux, firewalling, secure communications, certificate and key management, vulnerability management, antimalware protection, identity integration, and security patching. • Optimise capacity, performance, availability, monitoring, and resource utilisation, and diagnose complex issues across hardware, operating-system, network, storage, middleware, database, and application layers. • Plan and execute implementation, integration, testing, commissioning, migration, upgrading, and troubleshooting activities in laboratory and customer environments, providing technical support through project execution, warranty, and maintenance. • Produce and maintain architecture documents, detailed designs, drawings, test specifications and evidence, commissioning procedures, operational manuals, training materials, and reusable engineering knowledge, in accordance with project, quality, configuration, change-control, and scheduling requirements. • Collaborate with systems, hardware, software, cybersecurity, validation, operations, procurement, project, supplier, and customer teams to deliver coherent end-to-end solutions and provide customer-facing troubleshooting or training when required. • Contribute to the controlled evolution, standardisation, automation, and cost-effectiveness of the platform portfolio. Modernisation may include virtualisation and improved engineering practices; containerisation or cloud-native technologies may be incorporated where required in coordination with specialist profiles.
Your success is grounded in
