* Undertake or review protection coordination and settings activities, including fault studies and justification of protection performance, using recognised power-system analysis tools where required.
* Design and review substation control, automation and communication architectures, including bay-level and station-level systems.
* Apply IEC 61850 engineering principles, including data modelling, GOOSE messaging, MMS, Sampled Values where applicable, SCL files and multi-vendor system integration.
* Develop and review resilient station-bus and process-bus architectures, time synchronisation, network redundancy and segregation in accordance with applicable National Grid requirements, British Standards, BS EN/IEC standards and project procedures.
* Coordinate protection and control interfaces with primary plant, SCADA, telecommunications, metering, auxiliary systems, cybersecurity requirements and other substation disciplines.
* Take technical ownership of allocated P&C design packages and deliver them to the agreed quality, programme and budget requirements.
